I don't really play Ban Mis much...but DADGAD is great for its ease of fitting in a nice flowing bass part to a fingerpicking arrangement. I agree its worthwhile working out different tunes, since some are overdone and most overlooked...its hard work though and who likes that?The drawback to the sound that I find after awhile, is that its just too damn pretty. I like a little dissonance somewhere since I am not sitting on a cloud strumming a harp...However if you're like me and never practice, dissonance is not hard to come by...and you can get some interesting effects by trying to play in a key other than D without capoing--you get chords that sound sort of right but kind of weird and unsettling due to odd inversions I guess.
Did Davey Graham really invent it? I didn't know that.
