Watch the Week 3: Intro to Master Structure III online guitar lesson by Les Wise from Fretboard Freedom Fighter
This week you learn the third master structure - the dominant 7th arpeggio type. Playing it from every finger and string. This structure is also just a variation on the major 7th arpeggio. Just change one note of the major 7th structure, the 7th, and you have it. It is just that simple. You may have noticed, that if you learned the first master structure you can play them all.
