DAA or DAD as primary tuning ?
General mountain dulcimer or music discussions
I'm not sure that there's more options, just different ones. DAA is probably more useful to noter drone players because of the 'extra' notes below the 'D' on the 3rd fret but there's a lot more written data available for DAd. I imagine everyone starts by playing ND [noter/drone] style at first, it feels natural, and easy to do. Many folks never change to the chord style. It's one of the advantages of taking up this instrument, being able to play how, and what, you want and like.
