The purpose of this study was to investigate participant involvement in community wind bands through the lens of organizational theory to inform the music education profession about community wind bands as an "expressive" voluntary association with potential for lifelong participation. Twenty-eight informants were drawn from three community wind bands in the United States and four community wind bands in Singapore. Overall, responses between U.S. and Singapore informants shared many commonalities. Informants from both countries desired musical opportunities that aligned with their interests (incentives and commitment), viewed their participation as defined largely by the ensemble-conductor relationship (formal structures), and preferred rehearsing and performing under the direction of a competent and respectful conductor (leadership and authority). The diversity of bands from which informants were drawn points to the importance of an environment that supports a range of interests for lifelong participation.
