I just finished having dinner with a guitarist friend of mine.First off, let me tell you. I respect this guy. His playing is good, he writes interesting songs, overall i really dig what he does. We got to talking about theory, and the like. I found out he does everything completely by ear, he doesn't run over scales and modes and all those things i spend hours a day doing. In fact, he has very vague idea of what scales are, and doesn't even know what modes are. He doesn't do silly technical drills like me. Despite all this, he's a great player and he makes great music. I thought it was a nice reminder of how others perceive you versus how you perceive yourself.
