Thanx man. Now I got a little more knowledge behind those chords. I also agree with the last statement, the altered dominant (b5) doesn't appeal to me as much either. The "m7b5" is a much better b5 chord. The "b3" balances out the tones a little better.

I know this question wasn't addressed to me, and Griphon would no doubt give a better answer. But one piece that people are very intrigued by is "Beethoven's Fur Elise". Especially on classical guitar and I think it's subtle enough for the atmosphere and still recognizable enough to catch an eye or two. Because everybody knows it and not many have heard it played on guitar, and it sounds awesome. It should have been arranged for guitar to begin with. :) I play it all the time on bass and people are amazed at it's quality of tone. It's a feeble request and probably sounds like something a poseur would say, but it does really sound good. It's also simple so you could quickly start playing it in your repertoire.
