That's interesting, mooman. I never heard of a six-string dulcimer before.

I like D-A-A because I'm an alto, and the melodies are lower in D-A-A. Sometimes I tune it D-A-G and go off to a minor realm for a while, but then I go back to good old D-A-A.

I don't want to use any more tunings than that, because new tunings mean new chord positions, and that would take away some of the fun.
