I understand the "how" and I own several nice ones.
I know that some song lessons call for a capo and some of those songs do sound better with a capo.
But I have never understood why else to use one.
I do not understand how ones voice can be in a specific key.
I watch everyone from Johnny Cash to Neil Young playing open position chords with no capo.
I have been playing 4+ years and just don't get this part at all.
So enlighten me you guitar music wizards.
