From amateur collegiate a cappella groups to professional ensembles like Straight No Chaser and Pentatonix, contemporary a cappella has exploded onto the world pop music scene. This book combines historical context and a comprehensive look at the a cappella community with a detailed discussion of vocal techniques, rehearsal practices, and live audio support needed to sing great a cappella.
