Abstract

In the current literature regarding sleep quality, there is a large body of research devoted to the use of music as a sleep aid. Music has been shown to have a better efficacy for sleep improvement than other common sound treatments without the serious side effects of sleep medication. However, most sleep and music studies focus mainly on the sleep; there is a gap in the literature regarding which elements of music improve its efficacy as a sleep aid. The current study sought to examine the relationship between one specific element of music, pitch directionality, and the efficacy of music as a sleep aid. It also further examined relationships between musicianship and sleep quality as well as other components of well-being such as stress reduction. An Initial Survey was administered to 52 participants, and of that sample, 31 participants were administered four conditions of sound before sleep (silence, ambient noise, ascending music, and descending music). The primary hypothesis was that melodically descending music would improve sleep over melodically ascending music. The secondary hypothesis was that higher levels of musicianship will result in lower sleep quality with the presence of music. The tertiary hypothesis was that higher reported levels of musical engagement during the COVID-19 pandemic would result in lower reported stress levels during that time. Our results showed that the reported sleep quality scores for each sleep-sound condition were not significantly different from one another and that musicianship did not have a significant predictive effect on sleep quality in any condition. One subcomponent of musical engagement showed a significant predictive effect on reported stress such that as musical engagement increased, stress increased as well. Therefore, the results of the study did not support any of the hypotheses. However, an exploratory analysis showed several significant differences in mean survey scores and sleep sound condition responses between the Psychology department-affiliated students and the Music department-affiliated students. Possible future directions involve examining other technical elements of music in relation to sleep quality as well as reexamining the question of pitch directionality using the objective data lens of a controlled sleep lab environment.
