Although scholars theorize that identities are layered or nested within one another, little is understood about whether, how, and what layers are expressed by individuals. Such understanding could offer insight into organizational membership decisions, particularly within voluntary organizations where financial incentives are not involved. This study used semi-structured interviews to explore how individuals articulate identities and identification sources when discussing their desire to join and continue participation in a community choir, a voluntary leisure organization. The findings highlight how specific individual activities and higher order nested family and music identities, in addition to the more traditional organizational identifications, all play into membership decisions. The results also suggest that identity researchers and voluntary organization managers may benefit from focusing more attention on (a) higher order and cross-cutting social category identities, (b) individual activities in the organizations, and (c) the isomorphism among different layers of identity and identification.
