This study examined the effects of implied performer age and group membership on listeners' evaluations of music performances. Undergraduate music majors (n = 23), nonmusic majors (n = 17), and members of a New Horizons ensemble (n = 16) were presented with six 30-second excerpts of concert band performances. Excerpts were presented to all respondents in three implied performer age conditions: audio-only (no implied age), audiovisual presentations that featured digital images of middle school concert bands, and audiovisual presentations that featured digital images of older adult concert bands. Respondents (N = 56) used 10-point scales to rate each performance on tone, rhythmic precision, and dynamic contrast. Results of a repeated-measures analysis of variance indicated that audio-only presentations were rated significantly lower than audiovisual presentations, and music majors rated performances significantly lower than other respondents.
