Hello, When I first learned guitar, it was taught to me in the form of patterns (i.e. chord shapes, scale patterns /boxes). Recently, I learned the major scale numbering system (root = 1, etc). This has provided definition and reasoning behind the shapes and patterns - hugely helpful. Now I'm wondering if the next step is to be able to know the exact notes behind those numbers in each key (i.e. the sixth in the key of C is A)? Is this a worthwhile endeavor in terms of what it will add to my understanding of the guitar and ultimately my ability to play it? Thanks!
