ObjectiveThe purpose of this investigation was to assess the effects of three warm-up procedures (vocal-only, physical-only, physical/vocal combination) on acoustic and perceptual measures of choir sound.MethodsThe researchers tested three videotaped, 5-minute, choral warm-up procedures on three university choirs. After participating in a warm-up procedure, each choir was recorded singing a folk song for long-term average spectra and pitch analysis. Singer participants responded to a questionnaire about preferences after each warm-up procedure. Warm-up procedures and recording sessions occurred during each choir's regular rehearsal time and in each choir's regular rehearsal space during three consecutive rehearsals.ResultsLong-term average spectra results demonstrated more resonant singing after the physical/vocal warm-up for two of the three choirs. Pitch analysis results indicate that all three choirs sang “in-tune” or with the least pitch deviation after participating in the physical/vocal warm-up. Singer questionnaire responses showed general preference for the physical/vocal combination warm-up, and singer ranking of the three procedures indicated the physical/vocal warm-up as the most favored for readiness to sing.ConclusionsIn the context of this study with these three university choir participants, it seems that a combination choral warm-up that includes physical and vocal aspects is preferred by singers, enables more resonant singing, and more in-tune singing. Findings from this study could provide teachers and choral directors with important information as they structure and experiment with their choral warm-up procedures.
