This revolutionary book is an in-depth study guide for those who wish to further their understanding of guitar scale fingerings in an intelligent and orderly manner. All the essential western scales and modes are mapped out on the fretboard in easy-to-remember patterns that are perfectly logical, and - most importantly - 100% practical for ease of execution in performance. The descriptive use of color throughout enables the player to most clearly and graphically envision the differences and similarities between related scales and sections of scales. These are shown in various configurations designed to highlight the intervallic relationships and repetition of fragments between groups of strings. The exposition of fretboard systems presented in this handbook graphically demonstrates how simple fingering mastery of scales and modes can be via the internalization of just a few basic finger positions and their repeating combinations.
