I know GT has a very useful chord chart in the Toolbox section and I can recognise when some notes are taken away from the shape shown they would leave a chord triad in place

I think power chords cover dyads and triads on strings 4,5, and 6 but are there any reference points for making a triad or dyads on the higher strings and then strings 2-4 and 3-5

Dave and Mike and probably others cover triads in some of the extra tutorials but can only show you a couple in the time allowed while explaining the inversions.

Is it something you have to try for ourselves using the various open chord shapes and breaking down the chord they play as we move around the fret.

Are there too many permutations with inversions included to map this down anywhere
