I was wondering if someone would post the Shenkerian site---his ideas account for what happens in music in about as simple and straightforward a way as anyone has yet come up with--at least for the kind of music we play(it is a stretch to analyze 4'33, though)

Guitar is an instrument that plays counterpoint even when you don't want it to, and if you understand a bit of Shenker, it can help you to figure out what you've been doing, and what you need to do to get it right--

Or maybe if you've been playing guitar long enough, it helps you to understand Shenker--
