Globally, society is faced with an aging population and there is an increasing interest in active aging. This involves all facets of social participation and recognizes the potential contribution older people can make to their communities. This study considers music as a way for older people to engage actively with their communities and both give and receive considerable positive benefits. This single case study focuses on a small choir, the Happy Wanderers, formed by a group of older people to perform to residents in care facilities and to sufferers of dementia. The group has a well-established and busy performance schedule. Participation in the group enhances the lives of the members as well as those of their audiences. Several significant themes emerged in this discussion of community music engagement: gaining a sense of purpose and fulfilment; maintaining relationships; and personal growth.
