Bob Stoloff is an Associate Professor at Berklee College of Music. This book is a comprehensive how-to on vocal jazz scat technique. Beginning with an introduction to the history of scat and its evolution, it contains a virtual library of scales and exercises. Rhythmic, melodic and harmonic concepts, including modes, are discussed, with recommended methods for practice given. Also, vocal bass and percussion routines are explained. The accompanying CD allows the student to listen to examples, and then work on the exercises with rhythm-section accompaniment. 'Scat!' is an intensive program, based upon application, not dry theory. Fundamental sight-reading ability is required to do the exercises. This book is an excellent resource for the jazz vocalist seeking to develop their style.
