音乐用于医疗保健以促进身心健康。随着音乐的临床应用不断扩大，人们越来越需要了解音乐影响健康的生物机制。在这里，我们探讨集体歌唱的神经化学和社交流程。来自爵士声乐合奏团的四名参与者被方便地抽样在两场单独的表演中一起演唱：预先创作的和即兴创作的。在每次唱歌之前和之后测量血浆催产素和促肾上腺皮质激素（ACTH）的浓度，以评估社会归属、参与和唤醒水平。在每种歌唱条件后对心流状态进行经过验证的评估，以评估参与者对任务的吸收程度。评估了研究方法的可行性，并生成了集体歌唱的初始神经化学数据。心流状态量表的平均分表明，参与者在预作曲（M = 37.06）和即兴演唱条件（M = 34.25）下都经历了心流，条件之间没有显着差异。在这两种条件下，促肾上腺皮质激素浓度均下降，在预先创作的歌唱条件下显着下降，这可能有助于社交心流体验。平均血浆催产素水平仅随着即兴歌唱而增加，即兴歌唱和预先创作的歌唱条件之间没有观察到显着差异。结果表明，根据促肾上腺皮质激素（ACTH）测量，集体唱歌可以减轻压力和兴奋，并诱导参与者的社交流动。预先创作和即兴创作的集体演唱对催产素的影响尚不清楚。即兴创作状态下血浆催产素水平较高可能归因于与他人即兴创作音乐的社会影响。有必要进行更大样本量的进一步研究。
Music is used in healthcare to promote physical and psychological well-being. As clinical applications of music continue to expand, there is a growing need to understand the biological mechanisms by which music influences health. Here we explore the neurochemistry and social flow of group singing. Four participants from a vocal jazz ensemble were conveniently sampled to sing together in two separate performances: pre-composed and improvised. Concentrations of plasma oxytocin and adrenocorticotropic hormone (ACTH) were measured before and after each singing condition to assess levels of social affiliation, engagement and arousal. A validated assessment of flow state was administered after each singing condition to assess participants' absorption in the task. The feasibility of the research methods were assessed and initial neurochemical data was generated on group singing. Mean scores of the flow state scale indicated that participants experienced flow in both the pre-composed (M = 37.06) and improvised singing conditions (M = 34.25), with no significant difference between conditions. ACTH concentrations decreased in both conditions, significantly so in the pre-composed singing condition, which may have contributed to the social flow experience. Mean plasma oxytocin levels increased only in response to improvised singing, with no significant difference between improvised and pre-composed singing conditions observed. The results indicate that group singing reduces stress and arousal, as measured by ACTH, and induces social flow in participants. The effects of pre-composed and improvised group singing on oxytocin are less clear. Higher levels of plasma oxytocin in the improvised condition may perhaps be attributed to the social effects of improvising musically with others. Further research with a larger sample size is warranted.
