Has anyone ever heard if there is a piano for lefties?

Before I started school my mother went to the school teachers and told them I was left handed and to leave me alone. (A kid down the street developed mental function problems when the Brothers beat him into writing with his right hand.)

I play guitar , mandolin right handed. Also golf. I am told that some golfers at the PGA level play left handed even though they are naturally right handed.

I read many moons ago in a back page of the globe and mail (Canada) that cultures with a high proportion of left handedness have higher murder rates. Maybe this explains why the Latin for leftie is "sinister"...
