Watch the 7 Arpeggio online guitar lesson by Brad Carlton from Guitar Lab: Diamond Rock Rhythm
This lesson presents the 7 arpeggio which is simply the inclusion of the 3 to the 7 no3 arpeggio you learned in lesson seven. Diagram six shows this plotted out over the entire fingerboard. One way to view this is to see the guide tones which are the 3 and b7 added to the power chord arpeggio forms. These guide tones invert perfectly in that they are augmented fourths (6 half steps). That is why in diagram six the black scale degrees form the same shape throughout.
