The Effects of Three Physical and Vocal Warm-up Procedures on Acoustic and Perceptual Measures of Choral Sound: Study Replication With Younger Populations.
The purpose of this study was to replicate a previous investigation to assess with two intact children's choirs and a high school choir the potential effects of three choral warm-up procedures (vocal-only, physical-only, physical/vocal combination) on acoustic and perceptual measures of choral sound. ⋯ This study replication indicates similar conclusions as the original investigation with university choruses: a combination choral warm-up that includes both physical and vocal aspects is preferred by singers of all ages, enables more resonant singing, and more in-tune singing. Findings from these investigations provide choral educators with compelling information concerning efficient and effective choral warm-up procedures.
