This book features a collection of intermediate and advanced exercises and etudes designed for dedicated jazz vocalists aiming to enhance their improvisational abilities. Rooted in Bebop and traditional jazz sounds, it delves into common ii-V-I chord progressions, classic song structures, and popular jazz standards, presented in keys that are accessible for both male and female vocalists. Key subjects such as jazz theory, jazz scales, chord nomenclature, scat syllables, and fundamental jazz piano concepts are thoroughly examined. Additionally, the book provides downloadable recordings of all exercises and etudes, allowing readers to practice alongside Darmon Meader (voice and sax) and Rosana Eckert (voice).
