I'm writing a story based on the "Twa Sisters" ballad, the one where the harper "makes a harp from her breastbone". The story is about a serial killer who is obsedded with the ballad and attempts to make his own harp from his victim's brastbones, but I can't quite figure out how the harper made the harp! And suggestions or thoughts on this? An average breastbone is about 7 inches long. That would be an awfully small harp.
I told you it was a stupid question, but any suggestions would be greatly appreciated.
