Craig Derry's Vocal Boot Camp, New York

At Vocal Boot Camp, daily Vocal Bootcamp sessions put larynxes through their paces with a technique called vocal aerobics. Coaches also take extra care to develop solutions to colds, fatigue, stage fright, and accidental helium ingestion. Fast-paced exercises have students zipping up to high notes, harmonizing on the fly, and building endurance to stave off hoarseness.
