i'm trying to practice CAGED; right now what i'm doing is for each major and minor triad, i'm diagramming where all the positions are, starting with E-B-G strings, up the neck, then B-G-D strings, then G-D-A string, etc. i just started, and working with the 3 treble strings (E B G), it looks like, pattern-wise, the "C" and "D" shapes share the position. in other words, the sequence would go C/D--A---G--E--D/C---A--G--E--D/C--and so on. for example, working with the G major triad (G-B-D), on the first three strings, you could play it at the 7th fret as 7-8-7 along those strings. but, in the pattern, that seems to account for both the D and C shapes; after that, the next usable shape on those strings is 10-12-12, which is the A shap. does that make sense? is that correct?
