Matt Harris is one of the most fluent performers and teachers of jazz piano in the world today. This book lays the groundwork for strong voicings and voice leading by focusing primarily on the II-V-I progression, the most common chord progression in jazz. An invaluable section of this book is a collection of original melodies that are composed over chord progressions from many great popular and jazz standards. There are sample voicings in every key, chord progressions explaining the cycle of 4ths and 5ths, and up or down whole steps. The accompanying audio contains a slow and fast version of all the tunes with bass and drum accompaniment. The audio will make practicing fun and exciting while incorporating sophisticated voicings into a real-time musical situation.
