While much is known about the therapeutic qualities of music, less is understood about its impact on well-being from a holistic perspective. To address this limitation, this study examines how music is used as a resource to manage all aspects of well-being: physical, mental, intellectual and social. Adopting a transformative consumer research perspective, the researchers partnered with community organisations and participants in the design of the research. This study explores experiences of older adults (60–81) and adolescent teenagers (15–17) in Ireland over a seven-month period, using interviews, participant observation of intergenerational music workshops, and participant music diaries to explore this phenomenon. Findings place emphasis on the role of intergenerational social well-being in addition to the role of music in pain management, structuring the everyday, providing purpose, confronting death/uncertainty, and the management of identity formation/loss. Suggestions for social policy and future research are also explored.
