This is a great book for the intermediate guitarist, or for advanced players looking to move into the jazz arena. (Not for novices: only the first 29 pgs. out of 126 are beginner-level info. The learning curve gets a good deal steeper after that.) The book first walks you through basic jazz chord forms (with roots on 6th and 5th strings), then into inversions (seemingly every conceivable type!). Next, you get to deal with extensions, alterations, embellishments, and substitutions for I, II, and V chords (and, ultimately, any major, minor, or dominant). The rest of the book is fleshed out with smaller sections on triads, chord melody playing, comping, etc., which work to tie the concepts together. The format is mainly chord diagrams, indicating both fingering and note values (roots, 3rds, etc.). Works best taken in doses, working with each concept until absorbed. Used along with a study of scales/modes and their use around various chord shape, you could become a true fretboard master!
