Thanks for reply. Been playing autoharp for about two years. We have a big autoharp community here in SE Tennessee. I learn reallllll slow. I know the chord sequences for Dm, and thats why I use it: Amazing Grace (to House of Rising Sun melody), Greensleeves, Wayfairing Stranger, Scarbourgh Fair. Also, do lots of stuff in D since I play with lap dulcimers: Elizabeth's Waltz, Cabri Waltz, Pachelbels Canon, etc. I've rebuilt some old OS and Chromaharps to diatonics, but I can't carry fifteen autoharps with me like harmonicas, so I try to stay with my chromatic.Wilco In Tennessee
