The Effects of Three Physical and Vocal Warm-Up Procedures on Acoustic and Perceptual Measures of Choral Sound

In 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.
