Insomnia, prevalent in contemporary society, is characterized by difficulties in sleep initiation and maintenance, leading to fatigue, depression, and impaired cognitive function. Although research has demonstrated the sleep induction effects of certain musical genres, the neurophysiological mechanisms through which musical constituents, namely, melody, harmony, and rhythm, induce sleep remain inconclusive. To elucidate how musical constituents influence sleep onset, we used both subjective and objective measures, including the Pittsburgh Sleep Quality Index and Karolinska Sleepiness Scale as the former and electroencephalography (EEG) analysis as the latter. The EEG data showed that melody and harmony significantly enhance sleep quality, particularly impacting the theta band and the dispersion entropy in the temporal lobes. Conversely, the effect of rhythm in sleep induction appeared less significant, with minimal activity observed in the frontal and parietal lobes. We believe the data provide a foundation for innovative approaches to music composition that emphasize melody and harmony to enhance the therapeutic potential of music in sleep management, while de-emphasizing the role of rhythm. The findings also support adapting traditional musical forms, such as classical music, for sleep induction purposes and the development of sleep aid music composition rooted in Western music theory.
失眠在当代社会普遍存在，其特征是入睡和维持睡眠困难，会导致疲劳、抑郁和认知功能受损。尽管研究已经证明某些音乐流派具有助眠效果，但旋律、和声和节奏等音乐元素诱导睡眠的神经生理机制仍不明确。为了阐明音乐元素如何影响入睡，我们采用了主观和客观测量方法，前者包括匹兹堡睡眠质量指数和卡罗林斯卡嗜睡量表，后者则是脑电图（EEG）分析。EEG数据显示，旋律与和声能显著提高睡眠质量，尤其对颞叶的θ波段和离散熵产生影响。相反，节奏在诱导睡眠方面的作用似乎不太显著，额叶和顶叶的活动极少。我们认为这些数据为创新的音乐创作方法奠定了基础，这种方法强调旋律与和声，以增强音乐在睡眠管理中的治疗潜力，同时弱化节奏的作用。研究结果还支持为诱导睡眠而改编传统音乐形式，如古典音乐，以及开发基于西方音乐理论的助眠音乐作品。
