Expand and develop your six string theory with Danny Gill. Harmony and Theory is the language of music. It is what allows musicians from all over the world who may speak different languages verbally to speak the same language on their instrument. This DVD will guide you through the minor scale, relative keys, diatonic 7th chords, pentatonic scales, blues chord progressions, blues soloing, and extended chords. Each example is clearly demonstrated and performed with a backing track which is also included for you to play along with.
