Linnemann, A., Schnersch, A., & Nater, U. M. (2017). Testing the beneficial effects of singing in a choir on mood and stress in a longitudinal study: The role of social contacts. Musicae Scientiae, 21(2), 195-212.
What did the researchers want to know?
Can singing in a choir enhance mood and reduce stress? If so, do these effects increase over time, and/or are they associated with social contacts within the choir?
What did the researchers do?
Linnemann, Schnersch, and Nater studied 44 singers in an amateur university choir that rehearsed one evening per week for the duration of a semester. The participants completed a mood assessment questionnaire before and after each rehearsal, in which they rated their stress on a scale of 1-100 and rated their mood on six visual scales pertaining to three dimensions: calmness (agitated — calm; relaxed — tense), valence (unwell — well; content — discontent), and energetic arousal (tired — awake; full of energy — without energy). To explore connections between mood/stress and social contacts, participants were also asked to create a “social network map” (in which they indicated the number of their close friends, friends, and acquaintances who were also in the choir) and to rate their perceived social support within the choir. The researchers used a complex analysis called hierarchical linear modeling to compare each participant’s pre- and post-rehearsal scores as well as change throughout the semester.
What did the researchers find?
There were statistically significant differences in participants’ calmness and valence before and after choir rehearsals. On average, participants felt more calm and relaxed after choir rehearsals, as well as more content and well. There was also a statistically significant difference in pre- and post-rehearsal subjective stress levels, with participants generally reporting less stress after choir rehearsals than before.
There was no statistically significant increase in feelings of calmness and valence over time. However, participants did report feeling more energetic after choir as time went on, yet they reported feeling less awake (possibly due to the 10pm rehearsal ending time). Further examination of fluctuations over time indicates that participants actually experienced an increase in stress, discontent, and feeling unwell after rehearsals immediately preceding the first performance.
Number or type of social connections in the choir was not significantly related to changes in mood or stress.
What does this mean for my classroom?
Results of this study suggest that singing in a choir can have positive effects on mood and stress level, and these benefits may not be due simply to social connections with other choir members, as previous researchers have suggested. Music teachers should be aware of these benefits, share these benefits with others (e.g., students, parents, administrators), and encourage students to participate in singing. However, teachers should be mindful that rehearsals leading up to a performance can lead to increased stress and negative feelings among choir members and be sensitive to this when preparing for a performance.
