I finally got new strings for my autoharp!
It took about three hours just to remove the old zither pins and rusty strings, put in new strings and pins, and tune the whole thing, but it was worth it.
I als0 took out the black felt of the B flat Major chord bar and replaced it with new grey felt such that it plays E minor. Now I can play Aeroplane Over the Sea.
Autoharp music to follow.
