The cause of music consonance perception is not known, but consonance has been defined by both physical and perceptual characteristics. This study tested the extent of differences in interval perceptions and preferences in a non-musically trained group of adults. The independent variables of frequency range, condition of presentation, and harmonic intervals were judged for magnitude of preference. Results suggest that consonance preferences do not change when tones are heard in other frequency ranges or presentations. The findings also indicate that consonance preference may be a perceptual process that is not dependent upon frequency range or condition of presentation. Results of the study further imply that processes for aesthetic appreciation differ and are less demanding than aural discrimination processes. Charts and tables are included. (JHP)
