Continuing from Book 1, this second volume by Frank Gambale delves into more advanced soloing techniques for altered dominant, minor 7b5, and diminished chords. It explores complex scale approaches like the Diminished 1/2 Whole and Phrygian Major scales, as well as their corresponding arpeggios and triads. The material is designed to complete Gambale’s essential soloing theory course for intermediate to advanced guitarists.
