Teaching single note instrumentalists (including guitarists) how to hear and play thru chord changes, this is the essential elements of jazz. the play along CD has no chord instrument included, thus the student can hear the sound of the chord on his or her own. This is a method book in which everything is written out for the student, so in turn, just playing thru the exercises in this book with or without a teacher will clear up many questions about harmony. Editions come in Bass, E-flat, B-flat and Concert.
