The Spiral Galaxy Guitar Method (Electronic book text)

An essential component of the Fretography series, this is the guide to the diatonic fretboard. The Spiral Galaxy Guitar Method uses the principle of rotational (or radial) symmetry to fully examine and map the notes of the twelve diatonic keys. Rather than taking a piecemeal approach, this method shows you the big picture. Although some knowledge of basic theory is recommended, The Spiral Galaxy Guitar Method will benefit guitarists at all skill levels.
