The purpose of this study was to investigate constructions of choir identity among high school choir students in the United States public school classroom setting. The research questions were (a) what are the processes involved in construction of choir identity and (b) how are the processes related to the group identity of the choir. The data were collected through participant observations in one selected choir classroom and semi-structured interviews with students from the choir class. The results included six processes of identity construction as well as identification of the ways in which each process was related to the choir group’s identity. The processes and their links to the overall choir group identity provided further insight into the ways in which high school choir students construct their identities, and they also supported methods of teaching commonly used in high school choir settings.
