Murray,

I use DADGAD almost exclusively now. I started with it several years ago when I was mainly playing Irish and other Celtic music but since finding my way around the fretboard in this tuning now use it also for more bluesy and jazzy material. It is a very versatile tuning (listen to almost anything by Pierre Bensusan for confirmation). Since I am basically too lazy to keep retuning my guitar perhaps I have explored some of the additional and less obvious possibilities of DADGAD? There are, incidentally, a couple of online resources that give extensive chord charts in DADGAD tuning. Again, basically, I am too lazy to follow these and just noodle until I find something that fits!

Peace
