This book/CD set is a unique and complete system for exploring endless musical possibilities in any style. This book is a must for the contemporary musician. Despite being a guitar-friendly book with a complete mapping of the fretboard, the book is also useful for improvisers, arrangers, composers, theorists and students interested in the combinatorial approach to music. About 1,000 different voicings in all positions and drops are presented, including complete 3-note and 4-note voicings with specially designed guitar diagrams. The book also includes all triad-pairs (hexatonics) and their combinations in melodic exercises. The book presents brand new "combinatorial voice-leading", for 21st century chorale writing and contrapuntal exploring for any instrument or arrangement. In 312 pages, the book provides a vast store of material for compositional and improvisational use.
