Book excerpt: "...So much of the jazz harmonic language deals with the ii V I chord progression...[Students] have learned to play a lot of sophisticated voicings, but sometimes there is a lack of harmonic awareness and inner voice leading as well as a weak sense of how chords resolve in a ii V I progression as a unit...This book will give the jazz keyboard student and teacher a basic foundation for playing ii V I chord progressions and provide some lessons that can be used in the classroom or in private study...Knowing many different kinds of chords is fine, but it is equally important to know how to play one chord many different ways..."--preface.
