How to finger-pick "Handsome Molly" on an Appalachian dulcimer using a pinch-picking style based on Travis picking. I'm using a Galax dulcimer but any other dulcimer will work just as well.
Base tuning is dddd (D4, D4, D4, D4) with the outermost drone reverse-capoed on the third fret to raise it to a G. The final tuning is G4, D4, D4, D4. This starts an Ionian scale in the key of G on the third fret of the paired melody strings. The same fingering will work in DAA, CGG, bagpipe tuning, or in other tunings intended for the Ionian mode.
The tune is pentatonic, lacking the 4th and 7th scale degrees. Its tonic or key note is G, but it ends on the fifth (D) below the tonic. The mode is plagal, pentatonic Ionian (Bronson π1), aka Hypoionian.
Lisa has some well-thought-out noter-drone tab for this song HERE. Lisa's tune is a little different, but the picking works OK with either tune.
