Previous research suggests that students participating in school-based musical ensembles are more engaged in school and more likely to connect to their peers in school; however, researchers have not specifically investigated peer connectedness among adolescents in school-based music ensembles. The purpose of this study was to explore middle school band students' perceptions of peer connectedness. Participants (N = 317) indicated moderately high levels of peer connectedness both within the concert band and school. Levels of peer connectedness differed between schools; however, no statistical difference was found by grade/band level or SES. Suggestions for future research and implications for youth development and music education professions are discussed.
