I've never understood why there are right handed and left handed guitars and mandos. There aren't right and left handed pianos. And I've never met a left handed fiddler who bowed with his/her left hand. Why are guitars and mandos different?
Given how closely the right and left hands work together on a mandolin, it's hard for me to imagine that there's anything more than convention behind "handedness" on these instruments. But the demand for left handed instruments would seem to indicate that I'm missing something. Any left handers care to explain?
