Dulcimer String Anchor Pins
Instruments- discuss specific features, luthiers, instrument problems & questions
In any case, it appears you and I don't really disagree on the appropriate string gauges; we are just not sure how studentofrhythm has his dulcimer set up.
I agree that we don't really disagree. I was trying to find the appropriate strings for the first tuning he mentioned which was GDD. As I understand the pattern for identifying the notes by letters in the system we use, middle C is designated by a lower case "c". The octave below that is capital letters. The next octave lower is a capital letter followed by an apostrophe. The octave with middle c is lower case and the next octave above is lower case followed by an apostrophe.In American Standard Pitch Notation notes are designated by letter and octave; middle c being C4.
The original poster wants to tune his dulcimer "up to minor tuning." If that is D minor those notes would be D, F, A. I don't know whether one would tune those strings in the same octave giving a open minor when the dulcimer is strummed. I guess I need a more information and a better knowledge of music theory.
