This book is great for guitarists who have learned the basics of jazz harmony and improvisation. Topics include the ii-V-I progression, creating solo lines, altered chord formulas and "comping" in different jazz feels such as Latin, swing, ballad and even funk. Every new concept is accompanied by etudes and songs for practice, and every chapter is clearly divided into harmony and improvisation lessons. Packed with literally hundreds of chord voicings and improv ideas.
