I would like to be able to tune my 3-stringed diatonically fretted mountain dulcimer, typically stuck in the key of D, to other keys such as G, C, A, F, E, and Am. Then I would like someone to teach me how to figure out the notes on each fret so I can build the chords to play whatever song I'm in the mood for.
I'm going on a trip for a month and I don't want to bring my overly large guitar. Since I'd die without playing something, I figured I'd bring my mountain dulcimer, a fun little instrument I play with from time to time. My mountain dulcimer has a diatonic fret style (bottom image
), and is typically tuned DAD or DAA. This means the instrument is essentially tuned to the key of D, and you're limited to only a subset of the chords (for my purposes, D, A, G, Bm, Em). However, it is possible for me to capo the first fret on my dulcimer (no higher!!), so that gets some extra mileage. Furthermore, I can tune the low string anything between D and A, the middle string anything between B and E, and the high string anything between E and G.
First question: from those tuning possibilities and the capo, can any music genius teach me whether/how I can tune it to the majors keys? I'd love G, C, A, F, and Am.
Second question: Can you teach me how figure out the notes along each string given the open tuning of that string?
Third question: Once I have those notes, can you teach me how to build the basic chords?
Thanks in advance!
