I've seen various techniques on scale patterns. Such as memorizing 5-7 different scale patterns, 3NPS, etc.
But why do all that when we can just use CAGED? If you see the picture I have in this link, I could just go from root to root using the caged system to figure out my scales. It's my current theory that caged is all someone needs for both scales and chords. But I wanted to hear some thoughts on this.
