Great thread. Mooman is only one of several very talented people around here who pluck various kinds of strings on both melody and backing with great taste and, where appropriate, restraint. Our sessions are, however, sometimes invaded by people who might be good guitarists but clearly haven't grasped what Irish trad music is about.

Coincidentally, just today, one of the denizens of Chiff and Fipple has just put up a web page on DADGAD designed to help people who want to learn. It's all Greek to me, but looks convincing. Haven't had time to listen to the sound samples yet for positive confirmation. It's here.
