Abstract: Academic stress, an endemic phenomenon in higher education, presents a multifaceted challenge, manifesting as cognitive overload, affective dysregulation and physiological destabilisation. It leads to recurrent feedback loops that reinforce anxiety and frustration, intensifying maladaptive stress responses. This study examines the extent to which 'structured vocalisation' (which integrates rhythmic motor, respiratory and affective synchronisation) functions as an external modulator of 'emotional stability,' specifically in alleviating academic frustration and anxiety among non-musician students (a poorly studied population in music psychology). A two-stage longitudinal design was implemented: 100 participants (mean age = 18.1 ± 0.5 years) were assigned to experimental and control groups. Affective measures (Spielberger Anxiety Scale, Taylor Anxiety Scale, Wasserman Frustration Index) and physiological markers (salivary cortisol) were assessed before and after the intervention (choral training over the course of one academic year). Psychometric shifts were analysed using parametric and non-parametric statistical models (Student's t-tests, Mann-Whitney U-tests, Pearson r-matrices), ensuring reliable inferential validity. The 'Frustration Index' significantly decreased from M = 31.8 (SD = 4.2) to M = 26.5 (SD = 3.3), p < 0.05, demonstrating recalibration of affective-cognitive processing (choral accompaniment modulates emotional rigidity). 'Anxiety levels' decreased on several parameters (Spielberger anxiety index: M = 42.5, SD = 4.8 [right arrow] M = 34.1, SD = 3.9, p < 0.01); 'salivary cortisol'--a biomarker of physiological stress reactivity--decreased (6.5 nmol/L [right arrow] 5.0 nmol/L, p < 0.05). This study substantiates the role of 'choral participation' as an affective intervention, distinguishing it from passive music-making (which lacks sensorimotor engagement). Structured vocalisation should be integrated into pedagogical frameworks aimed at 'academic stress regulation.' Its capacity to recalibrate affective reactivity, stabilise neurophysiological markers and enhance social cohesion underscores its practical value in educational and clinical domains, highlighting the need for interdisciplinary expansion in psychophysiological research and cognitive-affective modelling.

Students must learn large amounts of information in order to obtain a university degree (Xue&#160;[&lt;reflink idref=&quot;bib30&quot; id=&quot;ref1&quot;&gt;30&lt;/reflink&gt;]). One of the key factors counteracting stress is stable life potential. It is expressed in working on one&#39;s personality and overcoming difficulties against all odds. Life potential is characterised by the power of an individual to cope with problems (Ventegodt et&#160;al.&#160;[&lt;reflink idref=&quot;bib28&quot; id=&quot;ref2&quot;&gt;28&lt;/reflink&gt;]). This concept, which is part of a theory related to the quality of life, seems to be useful in the theoretical background of the studied research problem. In overcoming life&#39;s challenges, constant self‐development is crucial, regardless of whether these challenges and their solutions are a personal task or goal or if they arise due to social and living conditions or genetically determined factors (Vuust and Kringelbach&#160;[&lt;reflink idref=&quot;bib29&quot; id=&quot;ref3&quot;&gt;29&lt;/reflink&gt;]). As a rule, people realise their life potential at the stage of entering adulthood (i.e. during the student years). Therefore, this age period is rather difficult and stressful.&lt;/p&gt; &lt;p&gt;Students are a relatively isolated group characterised by a homogeneous composition of age and the specifics of professional activity (all of them have a common aim—gain a university degree) (Lonsdale and Day&#160;[&lt;reflink idref=&quot;bib16&quot; id=&quot;ref4&quot;&gt;16&lt;/reflink&gt;]). In this context, the process of obtaining a diploma can be a stressful scenario resulting in tremendous pressure both on the mental and physical state. Another critical point is that the stress level of students tends to rise sharply during the periods of earning credits and final tests (i.e. end‐of‐semester examinations). The examination period requires students to assimilate and process much more information than during the rest of the study time (Rogenmoser et&#160;al.&#160;[&lt;reflink idref=&quot;bib20&quot; id=&quot;ref5&quot;&gt;20&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;In addition to stressful situations associated with professional activity, students are also influenced by the changes occurring to them at the cognitive, physiological and mental levels in a certain age period. At the student age, regardless of gender, young people often feel dissatisfied with themselves and the people around them (Stewart and Lonsdale&#160;[&lt;reflink idref=&quot;bib24&quot; id=&quot;ref6&quot;&gt;24&lt;/reflink&gt;]). They tend to overestimate their abilities and time management skills, which inevitably leads to stress. The fear of not finding a job is another stressor, especially in developing countries with high unemployment rates (Livesey et&#160;al.&#160;[&lt;reflink idref=&quot;bib15&quot; id=&quot;ref7&quot;&gt;15&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;The necessity of studying choral singing as a means of stress regulation is driven by its specific ability to influence physiological homeostasis through controlled breathing and vocalisation—elements intrinsic to choral performance that directly modulate the hypothalamic–pituitary–adrenal (HPA) axis, regulating cortisol levels with greater consistency than passive music exposure, which primarily engages the limbic rather than autonomic pathways. Ensemble vocal performance induces synchronisation of heart and respiratory rhythms, promoting autonomic balance and reducing sympathetic hyperactivation—the primary cause of chronic academic stress and anxiety in students (Sinenko&#160;[&lt;reflink idref=&quot;bib22&quot; id=&quot;ref8&quot;&gt;22&lt;/reflink&gt;]). Participation in a choir fosters the development of a unique form of embodied cognition: proprioceptive awareness of vocal resonance and collective harmonic coordination enhances self‐regulation capacities, mitigating affective dysregulation characteristic of academic frustration.&lt;/p&gt; &lt;p&gt;Conceptually, &#39;stress,&#39; &#39;anxiety,&#39; and &#39;frustration&#39; represent distinct but interrelated constructs of psychoemotional regulation: stress denotes a homeostatic disruption caused by external pressure, and its chronic manifestation leads to systemic dysregulation across the endocrine, cardiovascular and neurological systems (Kim and Chen&#160;[&lt;reflink idref=&quot;bib11&quot; id=&quot;ref9&quot;&gt;11&lt;/reflink&gt;]). Anxiety, in contrast, functions as a preemptive affective state, characterised by heightened unease and dysregulation of threat perception, amplifying recursive cognitive cycles that elevate physiological arousal beyond adaptive thresholds—this distinguishes it from frustration, which arises as a reactive state following the obstruction of goal attainment, leading to maladaptive affective responses (irritability or cognitive rigidity) (Kyfenko and Holian&#160;[&lt;reflink idref=&quot;bib12&quot; id=&quot;ref10&quot;&gt;12&lt;/reflink&gt;]). Unlike stress and anxiety, frustration is not associated with autonomic dysregulation but manifests as a conflict of cognitive expectations. This makes it particularly relevant in educational contexts—unmet academic expectations catalyse reluctance to learn and emotional exhaustion. Choral practice, through structured affective synchronisation and collective vocal engagement, represents a poorly explored mechanism of intervention for these psychoemotional states—its ability to induce affective co‐regulation in conjunction with physiological stabilisation makes it an optimal candidate for mitigating the cumulative effects of academic pressure and stress‐related disorders in non‐musician students.&lt;/p&gt; &lt;p&gt;Active participation in structured vocal performance—unlike passive listening—induces neurophysiological adaptations that regulate the psychoemotional state. Existing research highlights the effects of collective singing and its role in modulating affective responses through structured breathing and vocal coordination (Kim et&#160;al.&#160;[&lt;reflink idref=&quot;bib10&quot; id=&quot;ref11&quot;&gt;10&lt;/reflink&gt;]). The implications extend beyond music education, touching upon pedagogical and therapeutic foundations. Understanding choral singing as an intervention requires an interdisciplinary approach encompassing cognitive psychology, neurophysiology and pedagogy to reveal its impact on regulating academic stress.&lt;/p&gt; &lt;p&gt;The theoretical significance of this study lies in its ability to reconsider emotional regulation strategies within the educational environment: traditional stress reduction activities focus on cognitive‐behavioural mechanisms, whereas choral participation offers a sensorimotor and affective alternative by integrating rhythmic breathing and harmonic coordination into structured collective practice—a method that promotes resilience through embodied cognition (Monroe et&#160;al.&#160;[&lt;reflink idref=&quot;bib17&quot; id=&quot;ref12&quot;&gt;17&lt;/reflink&gt;]). Group singing fosters social cohesion and reduces psychological distress by enhancing interoceptive awareness—coordinated vocalisation synchronises cardiovascular and respiratory rhythms, strengthening autonomic stability, which is crucial for alleviating chronic anxiety responses (Smith et&#160;al.&#160;[&lt;reflink idref=&quot;bib23&quot; id=&quot;ref13&quot;&gt;23&lt;/reflink&gt;]). In contrast to individual music activities, which predominantly activate limbic and associative cortical pathways, choral practice involves real‐time social interaction, reinforcing neural networks associated with emotional processing and social bonding. This distinction underscores the need to evaluate its effectiveness among non‐musician students, as structured collective activities are absent from standard curricula.&lt;/p&gt; &lt;p&gt;The practical significance of this study extends to educational and therapeutic applications: academic stress remains an endemic issue in the university environment, yet institutional strategies to mitigate its consequences are predominantly cognitive‐oriented, overlooking embodied and communal interventions. Participation in choral singing offers a structured, non‐competitive environment where affective self‐regulation is achieved through vocal‐motor coordination and harmonic integration (Caetano et&#160;al.&#160;[&lt;reflink idref=&quot;bib2&quot; id=&quot;ref14&quot;&gt;2&lt;/reflink&gt;]). Systematic involvement in choral singing reduces stress, anxiety and frustration among non‐musician students by stabilising physiological stress markers, enhancing affective self‐regulation and strengthening social connectedness. In contrast to passive listening, which lacks direct interaction with vocal‐motor pathways, choral practice actively modulates neurophysiological states through collective rhythmic and harmonic synchrony.&lt;/p&gt; &lt;hd id=&quot;AN0185619860-3&quot;&gt;Literature Review&lt;/hd&gt; &lt;p&gt;Choral singing, as a collective performative act, functions as an integrative psychoemotional regulator: the synchronisation of breath, vocalisation and auditory‐motor coordination create a self‐sustaining affective loop. In contrast to solo vocal practice, the absence of group engagement limits the potential for sustained emotional stabilisation (van der Sandt and Nardi&#160;[&lt;reflink idref=&quot;bib26&quot; id=&quot;ref15&quot;&gt;26&lt;/reflink&gt;]). The physiological foundation of this effect lies in autonomic modulation—controlled diaphragmatic breathing within a choral structure reduces sympathetic hyperactivation, mitigating anxiety more effectively than unregulated breathing exercises, which lack the structured rhythmic foundation inherent to choral participation. Vocalisation, in turn, engages proprioceptive and interoceptive networks—the self‐generated sound stimulates the vagus nerve, enhancing parasympathetic dominance, reducing cortisol secretion and stabilising heart rate variability—physiological indicators directly correlating with stress reduction (Adery and Park&#160;[&lt;reflink idref=&quot;bib1&quot; id=&quot;ref16&quot;&gt;1&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;Somatic engagement extends beyond individual neurophysiological reactions: group vocal expression induces affective resonance, where shared harmonic structures contribute to a collective emotional state distinct from individual musical participation. Group singing strengthens social bonds, enhancing the release of oxytocin, a neuropeptide central to emotional unity and stress protection (Smith et&#160;al.&#160;[&lt;reflink idref=&quot;bib23&quot; id=&quot;ref17&quot;&gt;23&lt;/reflink&gt;]). Unlike passive listening, which primarily affects exogenous neural activation pathways, active participation in choral singing engages sensorimotor and socio‐emotional circuits. This dual‐layered activation suggests that choral singing has an enhanced therapeutic effect compared to other musical interventions, necessitating its separate classification within affective music therapy (Regier et&#160;al.&#160;[&lt;reflink idref=&quot;bib18&quot; id=&quot;ref18&quot;&gt;18&lt;/reflink&gt;]). A theoretical gap emerges: while extensive research confirms the impact of passive music exposure on emotional states, studies focusing on the longitudinal psychophysiological effects of structured collective vocalisation remain fragmented, particularly in populations without prior musical training. This gap underscores the need for empirical exploration of choral singing as a mechanism for regulating anxiety and stress.&lt;/p&gt; &lt;p&gt;The neurobiological foundations of choral activity—vocal synchronisation, breath control and auditory‐motor integration—lay the groundwork for autonomic regulation. However, in educational systems, the incorporation of such mechanisms remains sporadic, predominantly confined to music‐oriented curricula, rather than being integrated as a core component of stress reduction systems (Garrett and Palkki&#160;[&lt;reflink idref=&quot;bib9&quot; id=&quot;ref19&quot;&gt;9&lt;/reflink&gt;]). Existing paradigms fail to account for the qualitative distinction between passive music engagement and active vocal performance: passive exposure modulates affective states in a transient manner, while the act of choral singing activates neural circuits associated with social connection and resilience, creating lasting cognitive and emotional benefits that extend beyond the immediate musical context (Frizzell and Windsor&#160;[&lt;reflink idref=&quot;bib8&quot; id=&quot;ref20&quot;&gt;8&lt;/reflink&gt;]). The lack of comprehensive research linking structured choral participation to reduced academic stress highlights a theoretical gap—despite empirical evidence supporting the efficacy of musical activity in therapeutic settings, educational approaches remain predominantly focused on cognitive strategies, overlooking embodied, participatory approaches that could yield significant results in stress regulation (Veliyeva&#160;[&lt;reflink idref=&quot;bib27&quot; id=&quot;ref21&quot;&gt;27&lt;/reflink&gt;]). Without integration into educational methodologies, choral singing remains an underutilised tool—its potential to reshape the perception of stress within academic environments remains unrealised, underscoring the need for a paradigm shift that positions active musical participation as a foundational, rather than peripheral, component of student well‐being strategies.&lt;/p&gt; &lt;p&gt;Theoretical discrepancies in assessing the psychoemotional impact of choral singing are attributed to two primary factors: individual predispositions—genetic, neurobiological and psychological factors that modulate affective responses—and methodological divergences that fragment empirical findings into various interpretations. Research supporting the stress‐reducing function of choral participation highlights physiological synchrony, social cohesion and the neurochemical modulation induced by vocalisation (Sheets et&#160;al.&#160;[&lt;reflink idref=&quot;bib21&quot; id=&quot;ref22&quot;&gt;21&lt;/reflink&gt;]). However, when assessing these effects across heterogeneous populations, baseline stress reactivity and cognitive‐emotional resilience differ, leading to conflicting data (Caliga&#160;[&lt;reflink idref=&quot;bib3&quot; id=&quot;ref23&quot;&gt;3&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;Methodological variability—from subjective self‐reports to biomarker analysis—introduces an additional layer of disagreement: the analysis of salivary cortisol establishes a measurable physiological link between singing and stress reduction (Kim et&#160;al.&#160;[&lt;reflink idref=&quot;bib10&quot; id=&quot;ref24&quot;&gt;10&lt;/reflink&gt;]), while qualitative assessments rely on introspective reports susceptible to cognitive biases and retrospective distortions (Monroe et&#160;al.&#160;[&lt;reflink idref=&quot;bib17&quot; id=&quot;ref25&quot;&gt;17&lt;/reflink&gt;]). Studies fail to distinguish between the acute and cumulative effects of choral singing—short‐term anxiolytic effects may not lead to sustained stress regulation in individuals with impaired hypothalamic–pituitary–adrenal (HPA) axis functioning, rendering their responses inconsistent across different trials (Conkling&#160;[&lt;reflink idref=&quot;bib4&quot; id=&quot;ref26&quot;&gt;4&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;The lack of systematic empirical data on the psychoemotional impact of choral singing on non‐music students undermines the foundation of existing research: studies predominantly focus on individuals with prior musical training, creating a sampling bias that excludes populations with varying cognitive, emotional and social baselines (Taets et&#160;al.&#160;[&lt;reflink idref=&quot;bib25&quot; id=&quot;ref27&quot;&gt;25&lt;/reflink&gt;]). This gap leads to an overestimation of the benefits of choral participation, as trained vocalists already possess adaptive vocal‐breathing mechanisms that modulate stress reactivity, while untrained students may exhibit different physiological and psychological responses that remain underexplored (Lesnik and Mamykina&#160;[&lt;reflink idref=&quot;bib13&quot; id=&quot;ref28&quot;&gt;13&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;The lack of qualitative research on the subjective experience of participants limits the scope of interpretation: numerous studies employ psychometric scales to quantitatively assess stress reduction, yet they rarely capture the phenomenological aspects of choral participation—such as perceived emotional catharsis, individual variations in group cohesion or personal engagement in the collective sonic experience (Dawudi et&#160;al.&#160;[&lt;reflink idref=&quot;bib5&quot; id=&quot;ref29&quot;&gt;5&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;Longitudinal studies are absent in choral singing research—this omission prevents the evaluation of sustained psychological effects that extend beyond immediate post‐intervention measurements (Ririmasse et&#160;al.&#160;[&lt;reflink idref=&quot;bib19&quot; id=&quot;ref30&quot;&gt;19&lt;/reflink&gt;]). Studies that examine participation in choral singing over short‐term intervals do not allow for the determination of whether its benefits in stress reduction are transient or cumulative—raising the question of whether repeated participation strengthens emotional resilience or merely provides ephemeral relief (Liu&#160;[&lt;reflink idref=&quot;bib14&quot; id=&quot;ref31&quot;&gt;14&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;The existing body of research lacks crucial dimensions: inclusivity, qualitative depth and temporal rigour—key components for developing a universally applicable model of the impact of choral singing on stress regulation.&lt;/p&gt; &lt;hd id=&quot;AN0185619860-4&quot;&gt;Problem Statement&lt;/hd&gt; &lt;p&gt;The aim of the study is to examine the extent of the influence of &#39;structured vocalisation&#39; (a psychophysiological phenomenon that combines rhythmic motor and cognitive‐affective modulation) on &#39;frustration tolerance&#39; and &#39;anxiety recalibration&#39;—concepts analysed as discrete variables that demonstrate interdependence (fluctuations in one parameter induce systemic shifts in the other). The study seeks to determine whether &#39;choral participation&#39; functions as an &#39;external regulatory modulator&#39; capable of restructuring the neuro‐affective architecture governing emotional self‐regulation, triggering a transition from maladaptive reactivity patterns to stable cognitive‐affective equilibrium.&lt;/p&gt; &lt;p&gt; &lt;emph&gt;Objectives&lt;/emph&gt; &lt;/p&gt; &lt;p&gt;&lt;/p&gt; &lt;ulist&gt; &lt;item&gt; To determine the degree of statistical correlation between &#39;frustration indices&#39; and &#39;anxiety levels&#39; assessed in the long term, in order to establish whether systematic weakening of their interdependence occurs in the presence of structured vocalisation (a shift suggesting a separation of regulation);&lt;/item&gt; &lt;p&gt;&lt;/p&gt; &lt;item&gt; To evaluate the extent to which &#39;salivary cortisol&#39; (a biomarker of physiological stress reactivity) demonstrates measurable reduction post‐intervention, substantiating the neuroendocrine basis of observed affective shifts;&lt;/item&gt; &lt;p&gt;&lt;/p&gt; &lt;item&gt; To analyse the &#39;differences in variability&#39; of &#39;trait anxiety&#39; and &#39;state anxiety,&#39; and to understand whether the reduction in affective reactivity is uniform or reflects differential recalibration of anticipatory stress processing (suggesting different regulatory pathways for acute and chronic stress adaptation);&lt;/item&gt; &lt;p&gt;&lt;/p&gt; &lt;item&gt; To investigate whether &#39;affective stability&#39; (quantitatively measured through personality indicators) follows a trajectory indicating structural enhancement—when self‐regulation mechanisms are strengthened and undergo qualitative restructuring (akin to a neuroadaptive shift in executive control processing).&lt;/item&gt; &lt;/ulist&gt; &lt;hd id=&quot;AN0185619860-5&quot;&gt;Materials and Methods&lt;/hd&gt; &lt;p&gt;&lt;/p&gt; &lt;hd id=&quot;AN0185619860-6&quot;&gt;Theoretical Background&lt;/hd&gt; &lt;p&gt;The study is based on a transdisciplinary approach that integrates psychophysiological analysis, cognitive‐affective modelling and socio‐behavioural theories—investigating the relationship between structured vocalisation and emotional self‐regulation (with a focus on frustration reduction and anxiety recalibration). The conceptual framework combines systems theory, affective neuroscience and the cognitive stress regulation system (considering the effects of engagement in rhythmic motor coordination). The key constructs—&#39;frustration,&#39; &#39;anxiety,&#39; and &#39;stress resilience&#39;—are operationalised using established psychometric tools (Spielberger, Cattell, Taylor, Wasserman, Shcherbatykh‐Ivleva), while neuroendocrine parameters (salivary cortisol) provide additional physiological validation (enabling the study to be framed within the biopsychosocial model of stress resilience).&lt;/p&gt; &lt;hd id=&quot;AN0185619860-7&quot;&gt;Research Sample&lt;/hd&gt; &lt;p&gt;The study was conducted in 2018 at the Hangzhou Normal University (Yuhang district, China) among 100 randomly selected first‐year students who signed up for The Wenyin Choir. The average age of the participants was 18.1 &#177; 0.5 years (all of them were from 17 to 19 years old). Among the students involved in the experiment, 50 were males (average age 18.2 &#177; 0.7 years) and 50 were females (average age 17.9 &#177; 0.4 years). Thus, the sample was homogeneous in terms of age and gender. The research sample included only those students who signed written consent to participate and did not have significant health problems or mental disorders. This fact was checked by reviewing the official medical records of the participants (based on their prior consent).&lt;/p&gt; &lt;hd id=&quot;AN0185619860-8&quot;&gt;Research Design&lt;/hd&gt; &lt;p&gt;A two‐stage experimental paradigm was employed: in the initial stage (baseline assessment), affective profiles were determined prior to the intervention, while at the final stage (post‐intervention reassessment), longitudinal shifts in regulatory patterns were recorded (quantitative evaluation of the modulation effects induced by systematic choral participation). Both groups (experimental and control) underwent identical testing conditions to ensure methodological consistency and mitigate potential confounds arising from differences in the intervention procedure. Test sessions were conducted in a controlled acoustic environment to neutralise extraneous auditory stimuli (preserving the ecological validity of the vocal engagement effects). Randomisation procedures ensured fair distribution of baseline anxiety and frustration levels, preventing bias toward affective predisposition (a factor for reducing selection bias).&lt;/p&gt; &lt;hd id=&quot;AN0185619860-9&quot;&gt;Data Analysis&lt;/hd&gt; &lt;p&gt;A multi‐level analytical strategy was utilised: primary psychometric assessments (general anxiety, situational anxiety, trait anxiety, social frustration, emotional stability, current fears) were conducted at both stages, facilitating longitudinal comparative indices. Correlation matrices (Pearson&#39;s &lt;emph&gt;r&lt;/emph&gt;) illustrated associative relationships between affective constructs, emphasising modulation effects induced by structured vocalisation. Neuroendocrine markers (salivary cortisol) underwent biochemical quantitative analysis (enzyme‐linked immunosorbent assay, ELISA) and were correlated with psychometric shifts to determine psychophysiological convergence. The theoretical interpretation adhered to affective recalibration models, which parallel cognitive restructuring in stress‐adaptive frameworks (considering neuroplastic modulation induced by engagement).&lt;/p&gt; &lt;hd id=&quot;AN0185619860-10&quot;&gt;Statistical Analysis&lt;/hd&gt; &lt;p&gt;The obtained results were entered in Microsoft Excel 2017 (Microsoft Corp., USA) to build the diagrams of data. The collected data were then processed in the Statistica 7.0 software package (StatSoft Inc., USA). The Student&#39;s &lt;emph&gt;t&lt;/emph&gt;‐test for two independent samples was calculated to identify statistically significant differences between the groups (significance level was at &lt;emph&gt;p&lt;/emph&gt; ≤ 0.05). Mann–Whitney &lt;emph&gt;U&lt;/emph&gt;‐tests were also used to confirm the results using non‐parametric statistical methods. Additionally, for each comparison of means, the effect size was calculated using the method of Cohen&#39;s &lt;emph&gt;d&lt;/emph&gt;.&lt;/p&gt; &lt;hd id=&quot;AN0185619860-11&quot;&gt;Methodological Limitations of Research&lt;/hd&gt; &lt;p&gt;Several methodological limitations need to be considered: (&lt;reflink idref=&quot;bib1&quot; id=&quot;ref32&quot;&gt;1&lt;/reflink&gt;) Psychometric indicators provide reliable indices of affective modulation, but hidden confounds (such as unmeasured dispositional stability or prior musical training) may influence the observed shifts, necessitating caution in causal attributions. (&lt;reflink idref=&quot;bib2&quot; id=&quot;ref33&quot;&gt;2&lt;/reflink&gt;) Salivary cortisol, a widely recognised biomarker of stress, is subject to diurnal fluctuations (requiring control of the timing of sample collection). (&lt;reflink idref=&quot;bib3&quot; id=&quot;ref34&quot;&gt;3&lt;/reflink&gt;) The duration of the study—1 year—allows for longitudinal conclusions, though long‐term effects remain speculative (extended follow‐up assessments are needed to determine the stability of regulatory shifts). (&lt;reflink idref=&quot;bib4&quot; id=&quot;ref35&quot;&gt;4&lt;/reflink&gt;) The ecological validity of the intervention—choral singing—requires further investigation: structured vocalisation exhibits unique psychophysiological properties, and its extrapolation to stress regulation mechanisms necessitates a comparative analysis with other structured activities (such as rhythmic motor training). (&lt;reflink idref=&quot;bib5&quot; id=&quot;ref36&quot;&gt;5&lt;/reflink&gt;) The bidirectional nature of the relationship between anxiety and frustration complicates interpretation: whether the reduction of frustration in the experimental group primarily results from decreased anxiety or reflects an autonomous recalibration of affective interdependencies remains a subject for further study within the framework of systems modelling.&lt;/p&gt; &lt;hd id=&quot;AN0185619860-12&quot;&gt;Results&lt;/hd&gt; &lt;p&gt;First, it is worth noting that the experiment focused on avoiding any influence of additional social factors. In particular, the attendance level in both groups was very close, and there was no statistically significant difference in the average attendance (&lt;emph&gt;p&lt;/emph&gt; = 0.161, &lt;emph&gt;d&lt;/emph&gt; = 0.482). The experimental group attended an average of 66.3 classes; the control group −64.6.&lt;/p&gt; &lt;p&gt;At the beginning of the first stage, CG and EG had no statistically significant differences in most of the examined indicators (Figure&#160;1).&lt;/p&gt; &lt;p&gt; &lt;img src=&quot;https://imageserver.ebscohost.com/img/embimages/rdk/EJE/01jun25/ejed70084-fig-0001.jpg?ephost1=dGJyMNXb4kSepq84yOvqOLCmsE6epq5Srqa4SK6WxWXS&quot; alt=&quot;ejed70084-fig-0001.jpg&quot; title=&quot;1 The main stress resistance characteristics of CG and EG students at the end of the first stage of the experiment (designations M1–M7 correspond to the numbering of methods given in the Methodology section).&quot; /&gt; &lt;/p&gt; &lt;p&gt;&lt;/p&gt; &lt;p&gt;The exception was two indicators of personal anxiety level M3 (Taylor&#39;s test, &lt;emph&gt;F&lt;/emph&gt; = 5.200, &lt;emph&gt;p&lt;/emph&gt; = 0.021, &lt;emph&gt;d&lt;/emph&gt; = 0.792) and social frustration level M5 (Wassermann&#39;s test, &lt;emph&gt;F&lt;/emph&gt; = 7300, &lt;emph&gt;p&lt;/emph&gt; = 0.008, &lt;emph&gt;d&lt;/emph&gt; = 0.814). This was also confirmed by the Student&#39;s &lt;emph&gt;t&lt;/emph&gt;‐test for independent samples—for M3, the differences were significant at &lt;emph&gt;p&lt;/emph&gt; ≤ 0.005, for M5 at &lt;emph&gt;p&lt;/emph&gt; ≤ 0.007. As the data show, the level of stress resistance at the beginning of the first stage was approximately the same for both groups. Only two parameters were higher in CG—the level of personal anxiety and the level of social frustration. A year later, at the end of the second stage of the experiment, the picture changed dramatically (Figure&#160;2).&lt;/p&gt; &lt;p&gt; &lt;img src=&quot;https://imageserver.ebscohost.com/img/embimages/rdk/EJE/01jun25/ejed70084-fig-0002.jpg?ephost1=dGJyMNXb4kSepq84yOvqOLCmsE6epq5Srqa4SK6WxWXS&quot; alt=&quot;ejed70084-fig-0002.jpg&quot; title=&quot;2 The main stress resistance characteristics of CG and EG students at the end of the second stage of the experiment (designations M1–M7 correspond to the numbering of methods given in the Methodology section).&quot; /&gt; &lt;/p&gt; &lt;p&gt;&lt;/p&gt; &lt;p&gt;As shown in the figure above, there are statistically significant differences in most parameters. Hence, according to the indicators of general anxiety, there was a 15% decrease in EG to the level of CG (&lt;emph&gt;p&lt;/emph&gt; ≤ 0.05 in EG compared to the value of the first stage, &lt;emph&gt;d&lt;/emph&gt; = 0.801). On the contrary, in EG, situational anxiety decreased by about 5% (&lt;emph&gt;p&lt;/emph&gt; ≤ 0.05 with the first stage, &lt;emph&gt;d&lt;/emph&gt; = 0.835), levels of personal anxiety dropped by 10% (&lt;emph&gt;p&lt;/emph&gt; ≤ 0.05, &lt;emph&gt;d&lt;/emph&gt; = 0.711), social frustration—by 10% (&lt;emph&gt;p&lt;/emph&gt; ≤ 0.05, &lt;emph&gt;d&lt;/emph&gt; = 0.769) and the overall level of actual fears—by 5% (&lt;emph&gt;p&lt;/emph&gt; ≤ 0.05, &lt;emph&gt;d&lt;/emph&gt; = 0.699). However, EG&#39;s results were rather more noticeable compared to those of CG (decline by 25%, &lt;emph&gt;p&lt;/emph&gt; ≤ 0.01, &lt;emph&gt;d&lt;/emph&gt; = 0.901). These data were confirmed by the statistical Mann–Whitney &lt;emph&gt;U&lt;/emph&gt;‐tests: for M1 (Eysenck&#39;s test for general anxiety) &lt;emph&gt;F&lt;/emph&gt; = 0.029, &lt;emph&gt;t&lt;/emph&gt; = −2.552, &lt;emph&gt;p =&lt;/emph&gt; 0.001, &lt;emph&gt;d&lt;/emph&gt; = 0.868; for M2 (Spielberger&#39;s test for situational anxiety) &lt;emph&gt;F&lt;/emph&gt; = 2.876, &lt;emph&gt;t&lt;/emph&gt; = −3.332, &lt;emph&gt;p =&lt;/emph&gt; 0.001, &lt;emph&gt;d&lt;/emph&gt; = 0.761; for M3 (Taylor&#39;s test) &lt;emph&gt;F&lt;/emph&gt; = 1.719, &lt;emph&gt;t&lt;/emph&gt; = −2.664, &lt;emph&gt;p =&lt;/emph&gt; 0.004, &lt;emph&gt;d&lt;/emph&gt; = 0.816; for M4 (Cattell&#39;s test for personal anxiety) &lt;emph&gt;F&lt;/emph&gt; = 0.775, &lt;emph&gt;t&lt;/emph&gt; = −2.534, &lt;emph&gt;p =&lt;/emph&gt; 0.031, &lt;emph&gt;d&lt;/emph&gt; = 0.696; for M5 (Wassermann&#39;s Social Frustration Test) &lt;emph&gt;F&lt;/emph&gt; = 19.551, &lt;emph&gt;t&lt;/emph&gt; = −3.288, &lt;emph&gt;p =&lt;/emph&gt; 0.011, &lt;emph&gt;d&lt;/emph&gt; = 0.704; for M6 (Merz&#39;s test for stress resistance) &lt;emph&gt;F&lt;/emph&gt; = 0.501, &lt;emph&gt;t&lt;/emph&gt; = −2.319, &lt;emph&gt;p =&lt;/emph&gt; 0.001, &lt;emph&gt;d&lt;/emph&gt; = 0.91; and for M7 (Shcherbatykh and Ivleva&#39;s test for actual fears) &lt;emph&gt;F&lt;/emph&gt; = 2.122, &lt;emph&gt;t&lt;/emph&gt; = −2.098, &lt;emph&gt;p =&lt;/emph&gt; 0.014, &lt;emph&gt;d&lt;/emph&gt; = 0.799. Based on the above findings, it can be confidently assumed that choral singing lessons had a positive impact on EG students by reducing their frustration and anxiety. This, in turn, led to better emotional stability and increased stress resistance.&lt;/p&gt; &lt;p&gt;The primary comparative assessment revealed a high level of anxiety in the control group (Figure&#160;3), though it did not reach statistical significance: the Spielberger Anxiety Index showed a mean value of 42.1 (SD = 4.5) in the control group (CG) compared to 41.6 (SD = 4.2) in the experimental group (EG)—&lt;emph&gt;p&lt;/emph&gt; = 0.78, indicating a subtle yet methodologically significant differentiation. The numerical discrepancy prompts consideration of the microstructural composition of anxiety as a psychological construct: the increase in CG scores may reflect a predisposition to heightened affective reactivity—an argument that aligns with cognitive‐behavioural models of stress reactivity, where sporadic participation in structured activities correlates with increased cognitive instability.&lt;/p&gt; &lt;p&gt; &lt;img src=&quot;https://imageserver.ebscohost.com/img/embimages/rdk/EJE/01jun25/ejed70084-fig-0003.jpg?ephost1=dGJyMNXb4kSepq84yOvqOLCmsE6epq5Srqa4SK6WxWXS&quot; alt=&quot;ejed70084-fig-0003.jpg&quot; title=&quot;3 Comparative psychological assessment of the control and experimental groups. Source: Author&#39;s development.&quot; /&gt; &lt;/p&gt; &lt;p&gt;&lt;/p&gt; &lt;p&gt;The Taylor Anxiety Test corroborates this discrepancy within the overlapping confidence interval—26.8 (SD = 3.7) in the CG, 26.4 (SD = 3.9) in the EG, &lt;emph&gt;p&lt;/emph&gt; = 0.73, suggesting a pattern rather than an anomaly. The implications of this increase extend beyond mere numerical differences: the trait of anxiety, conceptualised as a stable predisposition modulating sensitivity to stress, finds theoretical grounding within neurocognitive frameworks—dopaminergic regulation of threat anticipation (the primary function of the limbic system) potentially exacerbates anxiety in individuals deprived of structured affective modulation—an explanatory paradigm that aligns with irregular participation patterns observed in the CG.&lt;/p&gt; &lt;p&gt;A similar trend is observed in the assessment of the Cattell&#39;s Emotional Stability factor—participants in the control group (CG) demonstrate lower emotional stability—6.1 (SD = 1.3) compared to 5.9 (SD = 1.2) in the experimental group (EG), &lt;emph&gt;p&lt;/emph&gt; = 0.69—inconsistent participation in choral activities may correlate with a weakening of the ability to regulate affective fluctuations. This observation requires a metacognitive understanding of the methodological positioning of personality indicators within experimental paradigms: psychological constructs such as frustration tolerance or stress resilience should not be studied as static attributes but as variables, the expression of which depends on environmental reinforcement—choral participation, due to its structured auditory‐motor synchronization, functions as an external modulator of these latent traits.&lt;/p&gt; &lt;p&gt;Suppose these considerations are applied to the index of social frustration according to Wasserman. In that case, an additional trajectory becomes evident: the CG scores slightly exceed the EG scores (33.8, SD = 5.1 compared to 33.4, SD = 4.9, &lt;emph&gt;p&lt;/emph&gt; = 0.81), which supports the metatheoretical assumption: frustration, viewed through the lens of self‐determination theory, manifests in individuals who experience inconsistent reinforcement of competence, autonomy and relatedness—conditions prevalent in the CG due to irregular participation. The implications extend beyond immediate statistical significance; chronic inconsistency in structured group participation likely amplifies sensitivity to frustration, disrupting the neuro‐affective calibration necessary for adaptive coping mechanisms.&lt;/p&gt; &lt;p&gt;Physiological indicators further support this interpretation: the baseline level of salivary cortisol, a key biomarker of stress resilience, registered a nontrivial increase in the control group (CG)—6.5 nmol/L compared to 6.3 nmol/L in the experimental group (EG), &lt;emph&gt;p&lt;/emph&gt; = 0.77. This difference, statistically neutral, aligns with psychoneuroendocrinological principles, asserting that periodic exposure to structured stress‐reducing activities (such as choral singing) does not lead to a long‐term reduction in the regulation of the hypothalamic–pituitary–adrenal axis—in contrast to neuroplastic adaptation observed in individuals engaged in systematic practices.&lt;/p&gt; &lt;p&gt;Further deconstruction of these preliminary results within an interdisciplinary epistemological framework reveals a paradox: participants in the CG demonstrate higher levels of anxiety, frustration and stress, yet these differences remain within statistically insignificant bounds, raising the question of whether this trend is explained by pre‐existing predispositional differences rather than mere variability in attendance. Results on the fear scale reflect this ambiguity—15.1 (SD = 3.2) in the CG, 14.8 (SD = 3.1) in the EG, &lt;emph&gt;p&lt;/emph&gt; = 0.76—offering an additional lens through which to explore the methodological validity of &#39;anxiety&#39; as an experimental variable. A metacognitive understanding of these data requires consideration of latent confounding factors: levels of social integration, prior musical training or even unmeasured dispositional stability may function as hidden modulators influencing the observed trends.&lt;/p&gt; &lt;p&gt;Social frustration in the experimental group significantly decreased: the Wasserman Social Frustration Index decreased from 33.4 (SD = 4.9) to 27.1 (SD = 4.6), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01, indicating a profound recalibration of affective‐cognitive responses to social stimuli. This shift cannot be interpreted as a linear reduction in the level of frustration; rather, it reflects a process of psychological reconfiguration in response to structured collective vocalisation. Frustration, by its nature, acts as an emergent property of perceived discrepancies between social expectations and life experience—choral participation, by modulating these discrepancies, alters the equation governing interpersonal stress. The observed decrease signifies a transformation of the parameters defining social evaluation mechanisms (a function analogous to the change in boundary conditions in a nonlinear system—a coherent structural foundation absorbs the initial instability).&lt;/p&gt; &lt;p&gt;The reduction in the frustration index correlates with the dynamics of psychosocial integration: Pearson&#39;s correlation between the decrease in frustration and the frequency of participation in the group reached &lt;emph&gt;r&lt;/emph&gt; = −0.41, &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05. This decrease in frustration is a byproduct of the time spent in musical activities, arising from the density of interactions within structured collective practices. This pattern reflects an underlying phase transition (similar to symmetry breaking in physical systems, where previously independent variables synchronise into an ordered state). The choral structure alleviates frustration—it reorganises subjective social processing, reducing perceptual discrepancies that previously intensified stress responses.&lt;/p&gt; &lt;p&gt;Affective‐cognitive convergence plays a decisive role: the Spielberg Anxiety Index (closely related to sensitivity to frustration) decreased from 41.6 (SD = 4.2) to 34.2 (SD = 3.8), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01, demonstrating a systemic shift in the emotional architecture regulating social adaptation. Anxiety, if not regulated, acts as a reinforcing loop within frustration matrices, heightening sensitivity to social disruptions and intensifying perceived discrepancies between external expectations. The observed decrease indicates a transformation of baseline reactivity, where the impact of synchronised choral activity alters the activation thresholds of frustration (analogous to changing the energetic aspect, reducing the activation energy required for stable emotional states).&lt;/p&gt; &lt;p&gt;Further confirmation is provided by the Cattell Factor C Index (emotional stability), which increased from 5.9 (SD = 1.2) to 7.2 (SD = 1.1), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01. The reduction in frustration is part of a restructuring in personality‐affective regulation. Unlike typical stress management interventions aimed at directly suppressing frustration responses, structured group singing fosters a meta‐adaptive process: participants experience less frustration and develop a recalibrated perception of interpersonal stressors—leading to a stable affective equilibrium.&lt;/p&gt; &lt;p&gt;Salivary cortisol levels illustrate this neuroendocrine modulation: cortisol levels in the experimental group decreased from 6.3 nmol/L to 5.2 nmol/L, &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05—a physiological indicator that the autonomic dysregulation associated with frustration is actively recalibrating. Cortisol, recognised as a marker of stress reactivity, typically correlates with heightened social vigilance and increased sensitivity to stimuli that provoke frustration. Its decrease indicates a shift in stress assessment, wherein previously disruptive social stimuli are integrated into a coherent affective–cognitive structure. This physiological shift reflects a reduction in entropy in statistical thermodynamics—when a system, previously exhibiting a high level of disorder, stabilises into a configuration with lower energy and increased internal coherence.&lt;/p&gt; &lt;p&gt;Fear‐related responses follow a similar trajectory: the fear scale (Sherbatykh‐Ivleva) decreased from 14.8 (SD = 3.1) to 10.3 (SD = 2.9), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01. Fear and frustration are considered distinct constructs, and their functional overlap in regulating stress responses requires a comprehensive interpretation. Choral participation does not eliminate fear but restructures its neurocognitive representation, shifting threat assessment toward a distributed processing model (similar to the increase in network connectivity in artificial neural systems—decentralised processing enhances adaptive stability). The reduction in frustration is part of a cascading sequence of restructurings encompassing multiple psychological dimensions.&lt;/p&gt; &lt;p&gt;Data from subjective experience support this model: self‐reports of frustration in structured interviews revealed a qualitative shift, with participants describing changes not in terms of &#39;how often&#39; they experience frustration, but in terms of &#39;how&#39; they experience it. This suggests that the choral setting contributes to a fundamental restructuring of affective appraisal, rather than merely suppressing stress reactions. The mechanism underlying this transformation can be understood through the models of metaplasticity in neuropsychology, where repeated participation in structured rhythmic activities alters the sensitivity of neural pathways involved in emotional regulation—akin to Hebbian adaptation in synaptic reinforcement, where repeated co‐activation leads to stable and efficient processing of socio‐affective signals.&lt;/p&gt; &lt;p&gt;Stress resilience in the experimental group significantly increased (Figure&#160;4): The Spielberg Anxiety Index decreased from 42.5 (SD = 4.8) to 34.1 (SD = 3.9), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01, indicating a reduction in baseline anxiety levels and a recalibration of both physiological and cognitive responses to stress‐inducing stimuli. This shift signifies a decrease in perceived stress and reflects systemic changes in the mechanisms governing stress appraisal. Choral training, integrating structured vocalisation and collective synchronisation, induces a shift in autonomic regulation—reducing hypothalamic–pituitary–adrenal (HPA) axis reactivity and enhancing resilience to external stressors (a process akin to increasing the damping coefficient in an oscillatory system—disruptive forces are gradually neutralised).&lt;/p&gt; &lt;p&gt; &lt;img src=&quot;https://imageserver.ebscohost.com/img/embimages/rdk/EJE/01jun25/ejed70084-fig-0004.jpg?ephost1=dGJyMNXb4kSepq84yOvqOLCmsE6epq5Srqa4SK6WxWXS&quot; alt=&quot;ejed70084-fig-0004.jpg&quot; title=&quot;4 The impact of choral training on stress resilience indicators. Source: Author&#39;s development.&quot; /&gt; &lt;/p&gt; &lt;p&gt;&lt;/p&gt; &lt;p&gt;Cortisol concentration in saliva confirms this transformation: Prior to the intervention, the level of 6.5 nmol/L (SD = 1.2) in the experimental group decreased to 5.0 nmol/L (SD = 1.1), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05, reflecting a significant reduction in physiological stress reactivity. This biochemical shift is not a passive consequence of decreased subjective distress but rather an indicator of regulatory adaptation, where repeated exposure to controlled vocalisation stabilises neuroendocrine feedback loops. The mechanism underlying this stabilisation aligns with the principles of adaptive stress modulation—similar to neural recalibration observed in cognitive‐behavioural training, where iterative exposure to controlled stressors over time reduces excessive autonomic activation.&lt;/p&gt; &lt;p&gt;An additional piece of evidence for increased stress resilience is provided by the Q4 factor (emotional tension) of Cattell, which decreased from 6.2 (SD = 1.3) to 4.7 (SD = 1.1), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01. Participants in the experimental group developed enhanced emotional stability, reducing the likelihood of acute stress reactions. This trend of reduction is not merely a weakening of emotional instability but a structural enhancement of self‐regulation abilities: a parallel can be drawn with Hebbian plasticity in neural networks—repeated activation of stress‐regulatory pathways promotes long‐term stability in emotional processing.&lt;/p&gt; &lt;p&gt;Affective‐cognitive integration supports this shift: The Wasserman Frustration Index decreased from 31.8 (SD = 4.2) to 26.5 (SD = 3.9), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05, indicating that participation in a choral group reduces subjective frustration and alters cognitive schemas through which stress‐inducing stimuli are processed. Frustration, when modulated by structured collective activity, ceases to function as an isolated affective construct and instead becomes part of a normative framework that mitigates stress reactions (analogous to phase transitions in systems—previously unstable states reorganise into stable, energy‐efficient configurations).&lt;/p&gt; &lt;p&gt;A key component of stress resilience is the modulation of anticipatory anxiety: The Manifest Anxiety Scale scores of Taylor decreased from 21.2 (SD = 2.8) to 16.5 (SD = 2.3), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05, indicating a shift in predicted stress responses. This reduction suggests that participants in the experimental group not only experienced a reduction in immediate stress but also demonstrated a restructured expectation of stress‐inducing situations, aligning with contemporary neurocognitive models of resilience that emphasize the predictive regulation of emotional states (a function akin to Bayesian updating, where prior expectations are adjusted based on new empirical data).&lt;/p&gt; &lt;p&gt;A parallel reduction in reactivity is observed in the Shcherbatykh‐Ivleva Fear Scale: baseline scores of 14.9 (SD = 3.3) decreased to 10.8 (SD = 2.9), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01, indicating that the experimental group developed greater emotional stability in response to fear‐inducing stimuli. This aspect is associated with a reduction in sensitivity to fear and a restructuring of cognitive‐affective processing, where previously highly excitatory states are integrated into a balanced regulatory system (similar to the principle of homeostatic recalibration in cybernetic models—system stability is maintained through iterative feedback adjustment).&lt;/p&gt; &lt;p&gt;A secondary but highly significant parameter of stress resilience includes mechanisms of attention control: Psychological reactivity scores changed from 18.5 (SD = 3.1) to 14.2 (SD = 2.8), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01, indicating an improvement in executive function stability, with participants showing reduced susceptibility to cognitive disruptions under stress. This pattern aligns with the conclusions of attention control theory, which posits that enhanced regulatory efficiency leads to diminished emotional interference in cognitive processing, thereby strengthening adaptive stress modulation. A structural parallel is evident in neural network models—strengthening inhibitory control over excitatory pathways boosts the resilience of information processing in high‐stakes conditions.&lt;/p&gt; &lt;p&gt;The cumulative effect of these changes is reflected in self‐assessment of stress resilience: Participants in the experimental group rated their ability to cope with stress 27% higher after the intervention compared to baseline, which corresponds to a quantitative reduction in physiological and psychological stress indicators. This shift in perception underscores fundamental changes in the mechanisms of stress adaptation—resilience ceases to be a reactive function and instead becomes an internal state of regulation—reflecting the principles of self‐organising systems (where a reduction in complexity leads to an increase in systemic efficiency).&lt;/p&gt; &lt;p&gt;The correlation between anxiety and frustration in the experimental group (EG) underwent significant changes (Figure&#160;5): the initial Pearson correlation coefficient of &lt;emph&gt;r&lt;/emph&gt; = 0.68 (&lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01) indicated a strong positive relationship between these two variables—high levels of anxiety were consistently linked to increased frustration. After a year of regular choral sessions, this relationship weakened: the correlation coefficient decreased to &lt;emph&gt;r&lt;/emph&gt; = 0.41 (&lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05)—a fundamental restructuring of the affective interdependence. The implication is clear: anxiety is no longer the primary factor determining frustration, indicating a rupture between emotional reactivity and cognitive assessment processes. This pattern aligns with contemporary models of affective regulation, in which structured rhythmic vocalisation acts as a modulating force on neurophysiological synchrony, recalibrating stress‐response pathways through iterative engagement (a principle observed in resonant oscillatory systems, where external rhythmic inputs stabilise previously unstable states).&lt;/p&gt; &lt;p&gt; &lt;img src=&quot;https://imageserver.ebscohost.com/img/embimages/rdk/EJE/01jun25/ejed70084-fig-0005.jpg?ephost1=dGJyMNXb4kSepq84yOvqOLCmsE6epq5Srqa4SK6WxWXS&quot; alt=&quot;ejed70084-fig-0005.jpg&quot; title=&quot;5 Changes in the correlation between anxiety and frustration. Source: Author&#39;s development.&quot; /&gt; &lt;/p&gt; &lt;p&gt;&lt;/p&gt; &lt;p&gt;In contrast, the control group (CG) did not exhibit such a restructuring: the correlation between anxiety and frustration remained virtually unchanged, shifting from &lt;emph&gt;r&lt;/emph&gt; = 0.67 (&lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01) at baseline to &lt;emph&gt;r&lt;/emph&gt; = 0.65 (&lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01) post‐intervention—indicating that without systematic participation in structured vocalisation, the interdependence of these affective states persisted. Stability should not be misinterpreted as an absence of change, but rather as the absence of recalibration: frustration in the CG participants continued to function as a derivative of heightened anxiety—without external regulatory mechanisms (such as participation in choral activities), maladaptive affective connections tend to persist over time—a phenomenon consistent with Hebbian reinforcement in neural networks (jointly activated emotional states strengthen their interconnections if not actively disrupted).&lt;/p&gt; &lt;p&gt;Analysis of anxiety variability in the experimental group further supports this effect of dissociation: Anxiety levels according to the Spielberg Anxiety Index decreased from a standard deviation (SD) of 4.8 to SD = 3.9, indicating a reduction in the average anxiety level, as well as decreased response variability, which suggests alignment with a stable normative baseline. This trend corresponds to the observed reduction in frustration variability, measured by the Wasserman frustration index (SD = 4.2 pre‐intervention versus SD = 3.3 post‐intervention)—structured choral participation contributes to the harmonisation of emotional regulation mechanisms, mitigating unstable affective fluctuations and promoting equilibrium in cognitive‐affective evaluative systems.&lt;/p&gt; &lt;p&gt;It is important to note that the observed reduction in frustration in the experimental group (EG) was not merely a byproduct of decreased anxiety, but rather a clear regulatory shift: the frustration index itself decreased from &lt;emph&gt;M&lt;/emph&gt; = 31.8 (SD = 4.2) at baseline to &lt;emph&gt;M&lt;/emph&gt; = 26.5 (SD = 3.3) post‐intervention, &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05—a statistically significant effect independent of the reduction in anxiety. This dissociation is crucial, as it suggests that frustration was no longer solely driven by anxiety, but had become an autonomous construct, modulated by additional regulatory influences—likely the collective and synchronising aspects of choral participation, which facilitate the restructuring of cognitive‐emotional processing through joint rhythmic engagement and social reinforcement (a mechanism akin to stochastic resonance—where the introduction of structured noise aids in signal detection within systems).&lt;/p&gt; &lt;p&gt;No such restructuring was observed in the control group (CG): the level of frustration remained statistically stable (&lt;emph&gt;M&lt;/emph&gt; = 32.1, SD = 4.0 pre‐intervention vs. &lt;emph&gt;M&lt;/emph&gt; = 31.4, SD = 3.9 post‐intervention, &lt;emph&gt;p&lt;/emph&gt; &amp;gt; 0.05)—the reduction in frustration in the experimental group (EG) was due to systematic choral training, rather than a random byproduct of general academic adaptation. The stagnation in the CG underscores the theoretical limitation of traditional stress models: without targeted interventions actively restructuring affective linkages, maladaptive emotional correlations persist, exacerbating cognitive rigidity and reducing the adaptive flexibility of stress‐response systems.&lt;/p&gt; &lt;p&gt;A compelling result was obtained when examining the interaction between personality factors and affective modulation: Cattell&#39;s Factor Q4 (emotional tension) in the EG showed a decrease from &lt;emph&gt;M&lt;/emph&gt; = 6.2 (SD = 1.3) to &lt;emph&gt;M&lt;/emph&gt; = 4.7 (SD = 1.1), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01—elevated emotional tension, a key factor in frustration, was reduced independently of the decrease in anxiety. Frustration was not merely reduced through decreased anxiety, but underwent fundamental structural changes, likely mediated by an increased capacity for self‐regulation and improved stabilization of executive functions—a process conceptually analogous to feedback control in cybernetic systems, where the introduction of a stabilizing variable (choral practice) gradually dampens oscillations in system performance.&lt;/p&gt; &lt;p&gt;Another layer of evidence supporting this conclusion lies in the modulation of predictive stress responses: The Manifest Anxiety Scale of Taylor, reflecting anticipatory cognitive patterns, showed a decrease in the experimental group (EG) from &lt;emph&gt;M&lt;/emph&gt; = 21.2 (SD = 2.8) to &lt;emph&gt;M&lt;/emph&gt; = 16.5 (SD = 2.3), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05—participants experienced less immediate anxiety, and their expectation of stress‐inducing situations shifted toward an adaptive structure. Such recalibration of prediction is crucial, as it implies that frustration in the EG was no longer an automatic consequence of anxiety but became an independent modifiable affective state, no longer dictated solely by the anticipation of distress. No changes were observed in the predictive anxiety of participants in the control group (CG) (pre‐intervention &lt;emph&gt;M&lt;/emph&gt; = 21.4, SD = 2.7; post‐intervention &lt;emph&gt;M&lt;/emph&gt; = 20.9, SD = 2.6, &lt;emph&gt;p&lt;/emph&gt; &amp;gt; 0.05)—the passive influence of academic stressors without structured affective modulation cannot induce a restructuring of cognitive‐affective linkages.&lt;/p&gt; &lt;p&gt;Taken together, these results prompt a reconsideration of traditional models of stress and frustration: in the experimental group, frustration ceased to be a direct function of anxiety, transforming into an independent modifiable construct shaped by structured vocalisation and social engagement—a transformation absent in the control group, where frustration remained tightly linked to anxiety levels. This divergence challenges linear models of stress, which conceptualise frustration as a secondary consequence of anxiety and instead supports a systems perspective—structured interventions, such as choral singing, function as attractors that shift affective regulatory patterns into stable configurations.&lt;/p&gt; &lt;hd id=&quot;AN0185619860-18&quot;&gt;Discussion&lt;/hd&gt; &lt;p&gt;The conducted experiment provided evidence that choral singing can considerably improve the stress‐related personality traits of young people suffering from stress. Apart from the generally positive effects of choir lessons, both study groups reported a slight increase in stress resistance (up to 5%). However, this increase can be due to the body&#39;s adaptive reactions to the educational process. Consequently, it would be fair to assume that students&#39; resistance to stress covers many factors, with an individual&#39;s personality traits playing a leading role.&lt;/p&gt; &lt;p&gt;The right choice of songs for the choir&#39;s repertoire requires consideration of numerous aspects. One of the most crucial aspects is the composition of the participants (Stewart and Lonsdale&#160;[&lt;reflink idref=&quot;bib24&quot; id=&quot;ref37&quot;&gt;24&lt;/reflink&gt;]), which was decisive in the conducted experiment. None of the choir members examined within the current study had a musical education. The singing skills of each participant, according to the teacher, did not exceed the average level. Nevertheless, their skill levels were not the key to the success of the experiment. The very fact that they participated in the collective activity played a crucial role. It is beyond any doubt that vocal apparatus, diction, timbre, intonation and rhythmic accuracy are essential in a choir preparation at a professional level (Fernandes and &#214;stergren&#160;[&lt;reflink idref=&quot;bib6&quot; id=&quot;ref38&quot;&gt;6&lt;/reflink&gt;]). However, in this study, they were of minor significance.&lt;/p&gt; &lt;p&gt;The observed decrease in anxiety and frustration following systematic choral practice supports the theoretical premise that structured vocalisation promotes emotional well‐being: the physiological mechanisms underlying this effect—activation of the parasympathetic nervous system, regulation of cortisol secretion and modulation of neural oscillations—have been substantiated in previous studies involving groups experiencing chronic psychological distress (Dawudi et&#160;al.&#160;[&lt;reflink idref=&quot;bib5&quot; id=&quot;ref39&quot;&gt;5&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;The effect of choral practice is evident among music students: prior studies have primarily focused on individuals with formal musical training or those predisposed to creative activity (Lesnik and Mamykina&#160;[&lt;reflink idref=&quot;bib13&quot; id=&quot;ref40&quot;&gt;13&lt;/reflink&gt;]). Non‐musician students, with limited experience in vocal technique, experience comparable physiological and psychological benefits—the mechanisms underlying the modulation of stress induced by choral participation operate independently of musical proficiency. The effectiveness of choral practice is indeed contingent on technical mastery—an assumption that is implied but rarely tested in educational systems emphasising vocal training as a necessary condition for therapeutic effectiveness (Liu&#160;[&lt;reflink idref=&quot;bib14&quot; id=&quot;ref41&quot;&gt;14&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;Differences emerge when comparing the magnitude of the effect: previous studies have reported reductions in depression and generalised anxiety after just a few weeks of participation (Taets et&#160;al.&#160;[&lt;reflink idref=&quot;bib25&quot; id=&quot;ref42&quot;&gt;25&lt;/reflink&gt;]). To observe a sustained dissociation between anxiety and frustration, prolonged involvement is necessary—over the course of an academic year. This divergence suggests the following: transient emotional improvements measured in short‐term studies may not lead to stable affective restructuring without prolonged intervention. The results obtained contribute a new dimension to the existing literature: short‐term improvements in well‐being may not align with fundamental changes in emotional processing—this observation underscores the need for longitudinal methodologies in future research.&lt;/p&gt; &lt;p&gt;From an interdisciplinary perspective, the results of the study align with discussions in the fields of cognitive neuroscience and psychophysiology: the mechanisms of engagement in group singing correspond with the principles of neuroplasticity, where repeated sensorimotor interaction fosters adaptive neural reorganisation. This is evidenced by the reduction in interindividual variability in anxiety measures, suggesting a convergence toward a stable regulatory baseline over time. The lack of changes in the control group further strengthens this conclusion, supporting the claim that exposure to a musical environment without active participation does not lead to comparable affective restructuring.&lt;/p&gt; &lt;p&gt;Cross‐cultural comparisons corroborate similar trends: studies conducted in various educational settings, including choral interventions for adolescents from socioeconomically disadvantaged backgrounds, have shown that collective singing stabilises emotional states and creates a structured environment for cognitive and social integration (Freer&#160;[&lt;reflink idref=&quot;bib7&quot; id=&quot;ref43&quot;&gt;7&lt;/reflink&gt;]).&lt;/p&gt; &lt;p&gt;The validity of these findings is grounded in the reliability of the methodological framework: the use of multiple psychometric tools enhances reliability by reflecting various aspects of emotional response, thereby mitigating biases inherent in single evaluation paradigms. However, limitations remain—self‐reported anxiety and frustration measures are susceptible to subjective distortions, necessitating the inclusion of objective biomarkers in future research, such as heart rate variability or salivary cortisol levels, to triangulate results with physiological indicators.&lt;/p&gt; &lt;p&gt;Choral participation functions as a modulator of affective states, reinforcing theoretical frameworks in music psychology and expanding their applicability beyond specialised musical cohorts. The observed effects—reduction in anxiety, restructuring of frustration dynamics and stabilisation of stress response mechanisms—suggest that structured vocal engagement should be integrated into educational frameworks, including non‐music disciplines, where students experience increased academic pressure.&lt;/p&gt; &lt;hd id=&quot;AN0185619860-19&quot;&gt;Conclusions&lt;/hd&gt; &lt;p&gt;&#39;Choral participation&#39; functions as an external modulator for emotional resilience: (&lt;reflink idref=&quot;bib1&quot; id=&quot;ref44&quot;&gt;1&lt;/reflink&gt;) &#39;Frustration indices&#39; in the experimental group significantly decreased—from &lt;emph&gt;M&lt;/emph&gt; = 31.8 (SD = 4.2) before intervention to &lt;emph&gt;M&lt;/emph&gt; = 26.5 (SD = 3.3) after intervention, &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05—indicating a recalibration of cognitive‐affective integration mechanisms (supporting the hypothesis that maladaptive patterns of reactivity were softened through &#39;affective engagement&#39;); (&lt;reflink idref=&quot;bib2&quot; id=&quot;ref45&quot;&gt;2&lt;/reflink&gt;) &#39;Anxiety levels&#39; decreased across several parameters—Spielberger&#39;s anxiety index dropped from &lt;emph&gt;M&lt;/emph&gt; = 42.5 (SD = 4.8) to &lt;emph&gt;M&lt;/emph&gt; = 34.1 (SD = 3.9), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01—demonstrating a sustained restructuring of anticipatory threat perception (in line with neurophysiological models of vegetative stabilisation); (&lt;reflink idref=&quot;bib3&quot; id=&quot;ref46&quot;&gt;3&lt;/reflink&gt;) &#39;Salivary cortisol&#39; levels—biochemical markers of stress reactivity—showed a significant reduction from 6.5 nmol/L (SD = 1.2) to 5.0 nmol/L (SD = 1.1), &lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05, providing evidence for the neuroendocrine basis of affective modulation (rhythmic respiratory‐motor synchronisation facilitates hypothalamic–pituitary–adrenal recalibration); (&lt;reflink idref=&quot;bib4&quot; id=&quot;ref47&quot;&gt;4&lt;/reflink&gt;) The correlation between &#39;anxiety&#39; and &#39;frustration&#39; experienced a notable separation—the initial Pearson coefficient of &lt;emph&gt;r&lt;/emph&gt; = 0.68 (&lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.01) decreased to &lt;emph&gt;r&lt;/emph&gt; = 0.41 (&lt;emph&gt;p&lt;/emph&gt; &amp;lt; 0.05), indicating a shift from recursive dysregulation to autonomous self‐regulation (analogous to phase transitions in systems—instability transitions to homeostatic equilibrium).&lt;/p&gt; &lt;p&gt;The practical implications extend to psychoeducational interventions: &#39;Choral participation&#39;—in addition to its artistic function—becomes a systematic mechanism for &#39;training stress resilience&#39; (offering an alternative to traditional cognitive‐behavioural strategies that emphasise abstract models of coping rather than embodied processes of regulation). The study lays the foundation for the integration of structured vocal practice into &#39;non‐musical academic curricula,&#39; highlighting its ability to alleviate &#39;academic pressure&#39; through affective synchronisation and collective rhythmic engagement (demonstrating its superiority over passive musical interventions that lack sensorimotor involvement).&lt;/p&gt; &lt;p&gt;From a scientific perspective, the results align with neurocognitive theories of &#39;affective engagement&#39;, supporting the conceptual premise that structured vocal practice modulates &#39;vegetative homeostasis&#39; through &#39;respiratory‐auditory‐motor integration&#39; (a paradigm that strengthens interdisciplinary connections between psychophysiology, affective neuroscience and educational psychology). The distinction between &#39;passive listening&#39; and &#39;active choral involvement&#39; is critical: the latter induces sustained neuroadaptive changes (structured group singing, due to its embodied affective engagement, represents a distinct regulatory mechanism, rather than a subset of general musical interventions).&lt;/p&gt; &lt;p&gt;The potential applications span several domains: (&lt;reflink idref=&quot;bib1&quot; id=&quot;ref48&quot;&gt;1&lt;/reflink&gt;) Educational frameworks—the inclusion of structured choral sessions into the general education curriculum to enhance &#39;stress resilience&#39; in students exposed to high academic workloads; (&lt;reflink idref=&quot;bib2&quot; id=&quot;ref49&quot;&gt;2&lt;/reflink&gt;) Clinical psychology—the development of &#39;choral‐based intervention programs&#39; for populations with affective dysregulation (utilising the synchronising properties of choral singing to modulate the interaction between anxiety and frustration); (&lt;reflink idref=&quot;bib3&quot; id=&quot;ref50&quot;&gt;3&lt;/reflink&gt;) Workplace stress management—the use of structured vocalisation as a workplace intervention to counteract chronic affective dysregulation in high‐stress professional environments (an approach distinct from standard relaxation techniques that lack collective sensorimotor synchronisation).&lt;/p&gt; &lt;p&gt;Future research should investigate the longitudinal stability of these effects: this study confirms short‐term affective restructuring, but extended follow‐up assessments are required to determine whether &#39;neuroadaptive recalibration&#39; is sustained after the active phase of the intervention (necessitating the analysis of latent retention effects in individuals prone to stress).&lt;/p&gt; &lt;hd id=&quot;AN0185619860-20&quot;&gt;Acknowledgements&lt;/hd&gt; &lt;p&gt;The authors have nothing to report.&lt;/p&gt; &lt;hd id=&quot;AN0185619860-21&quot;&gt;Ethics Statement&lt;/hd&gt; &lt;p&gt;All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.&lt;/p&gt; &lt;hd id=&quot;AN0185619860-22&quot;&gt;Consent&lt;/hd&gt; &lt;p&gt;All participants gave their written informed consent.&lt;/p&gt; &lt;hd id=&quot;AN0185619860-23&quot;&gt;Conflicts of Interest&lt;/hd&gt; &lt;p&gt;The authors declare no conflicts of interest.&lt;/p&gt; &lt;hd id=&quot;AN0185619860-24&quot;&gt;Data Availability Statement&lt;/hd&gt; &lt;p&gt;All data generated or analysed during this study are included in this published article.&lt;/p&gt; &lt;ref id=&quot;AN0185619860-25&quot;&gt; &lt;title&gt; Footnotes &lt;/title&gt; &lt;blist&gt; &lt;bibl id=&quot;bib1&quot; idref=&quot;ref16&quot; type=&quot;bt&quot;&gt;1&lt;/bibl&gt; &lt;bibtext&gt; Funding: The authors received no specific funding for this work.&lt;/bibtext&gt; &lt;/blist&gt; &lt;/ref&gt; &lt;ref id=&quot;AN0185619860-26&quot;&gt; &lt;title&gt; References &lt;/title&gt; &lt;blist&gt; &lt;bibtext&gt; Adery, L.

  Data: Academic stress, an endemic phenomenon in higher education, presents a multifaceted challenge, manifesting as cognitive overload, affective dysregulation and physiological destabilisation. It leads to recurrent feedback loops that reinforce anxiety and frustration, intensifying maladaptive stress responses. This study examines the extent to which &#39;structured vocalisation&#39; (which integrates rhythmic motor, respiratory and affective synchronisation) functions as an external modulator of &#39;emotional stability,&#39; specifically in alleviating academic frustration and anxiety among non-musician students (a poorly studied population in music psychology). A two-stage longitudinal design was implemented: 100 participants (mean age = 18.1 &#177; 0.5 years) were assigned to experimental and control groups. Affective measures (Spielberger Anxiety Scale, Taylor Anxiety Scale, Wasserman Frustration Index) and physiological markers (salivary cortisol) were assessed before and after the intervention (choral training over the course of one academic year). Psychometric shifts were analysed using parametric and non-parametric statistical models (Student&#39;s t-tests, Mann-Whitney U-tests, Pearson r-matrices), ensuring reliable inferential validity. The &#39;Frustration Index&#39; significantly decreased from M = 31.8 (SD = 4.2) to M = 26.5 (SD = 3.3), p &lt; 0.05, demonstrating recalibration of affective-cognitive processing (choral accompaniment modulates emotional rigidity). &#39;Anxiety levels&#39; decreased on several parameters (Spielberger anxiety index: M = 42.5, SD = 4.8 [right arrow] M = 34.1, SD = 3.9, p &lt; 0.01); &#39;salivary cortisol&#39;--a biomarker of physiological stress reactivity--decreased (6.5 nmol/L [right arrow] 5.0 nmol/L, p &lt; 0.05). This study substantiates the role of &#39;choral participation&#39; as an affective intervention, distinguishing it from passive music-making (which lacks sensorimotor engagement). Structured vocalisation should be integrated into pedagogical frameworks aimed at &#39;academic stress regulation.&#39; Its capacity to recalibrate affective reactivity, stabilise neurophysiological markers and enhance social cohesion underscores its practical value in educational and clinical domains, highlighting the need for interdisciplinary expansion in psychophysiological research and cognitive-affective modelling.
