Mountain Dulcimer is tuned D–A–D, with frets 1 to 17 laid out diatonically plus the 6+ and 13+ frets — D#, F and A# sound nowhere on it. Only the chords and notes its diatonic frets reach are charted, and the 6+ fret (between 6 and 7) counts as a fret of its own.

Browse alternate voicings to find the one that sits best under your fingers, then compare it with the other chord types built on D or explore the same shape in nearby keys. The diagrams list the notes in each voicing so you can connect the shape to the theory behind it.
