The Underlying Mechanisms of Social Bonding in Choral Singing: A Review of the Literature

Choral singing activates a range of psychological, psychosocial, and physiological mechanisms that shape how participants connect with one another. These mechanisms include interpersonal synchrony, the release of bonding-related neurochemicals, shared heart and respiratory patterns, and psychological processes that support emotional regulation and belonging. The purpose of this literature review is to synthesize interdisciplinary research to explain how these mechanisms interact to enhance social bonding in choral contexts. Integrating group singing into general music classes and applying these principles within choir curricula can support students’ emotional growth, stress management, and peer empathy. By designing activities that emphasize synchrony, coordinated breathing, and collaborative interaction, music educators can intentionally leverage these mechanisms to strengthen classroom communities and foster both social and emotional well-being.
