All that kind of stuff. I am not going to pretend to say that I am comfortable with this kind of thing. I am not. I've mentioned on this board a few times that when I started playing decades ago, I avoided it all like the plague. I wanted to be 'self taught'...that actually went pretty well for me.
but.............
I could have been that much better had I understood what I could do inately. I'm finding this to be a hinderance now.
In the 80's, I was playing metal.....Chord theory? Naw > Barre Chords.
Now I'm playing much more finessed, musically diverse and with much more acoustic influence....and I would love to have a command of chord structures.
Where you place your fingers on a chord has a name...if you know that, you know the fretboard.
