One of the finest books available on jazz guitar chords. Joe covers all the bases with two sections on chord forms and chord passages. Chords are divided into sixcategories: Major, Seventh, Augmented, Minor, Diminished, and Minor Seventh Flat Fifth, each showing substitutions and inversions that Joe would play when confronted with "basic" chord symbols. The chord passage section is divided into nine categories, including such topics as Major Sounds, Diminished Sounds, Augmented Sounds, Standard Patter Chord Substitutions, and other chord progression - related topics.
