This Backing track is in the G Mixolydian mode, this is the fifth mode of C Major. There are 4 pages of diagrams with three neck diagrams per page. These diagrams cover G Mixolydian three notes per string shapes, Dm Pentatonic , extended arpeggios from G Mixolydian, and the G Dominant Penatatonic scale. Dm Pentatonic is included because playing a pentatonic scale a 5th above the root of a Major chord can imply the Mixolydian Mode. This is because the Dm pentatonic includes G Major's b7 interval F. The b7 is the signature tone of the Mixolydian Mode.
