Honestly, everything musically for me is a struggle. If I don't play regularly, it shows. If I don't break everything down, it shows (nothing is really intuitive with me). Nothing really comes instinctively either, which means I can't really sing and play at the same time.
I played with a bunch of really good musicians in Philly, and some of these guys talked musical theory like it was street slang. I can remember the saxes playing a run, and one of them stopped and said to us (the banjos/guitars), "play this chord: (and he rattled off four notes)". He just knew this shit like it was writing his name. I would love to have that vocabulary, but I don't know what I'd give up to get it.
