...oh and my C-D diatonic autoharp is set up this way:
gcdedgabccddeeff#ggaabbccddeeff#ggabccdd and it has thirty eight strings. The chord bars are in two lines and are:

Dmin E*7 Amin B*7 Emin F# Bmin
F G7 C D7 G A*7 D

With these two harps I can play a wide range. I also have a G harp and an F harp and various standard 15 bar harps....*sigh* If I played a real harp I might have to lug around fewer instruments!...harpalong
