The purpose of this book is to give you a single source to refer to when looking for information regarding the use of scales for improvisation. This is not a method. Rather, it is a reference book. You can look up any chord to learn what scales will work with it. You can also look up any scale to learn every chord it works with. You will find two fingering diagrams for every scale and several voicings for the chords. Standard notation and TAB.
