Not relative to me, as I am definitely NOT a piano player.  That's why I hang out here, instead of on a piano forum somewhere, if there are such things.
Is there electricity on the desert island?  If so, I would leave the piano at home, or make a boat out of it.  

My mother was a great pianist; she could play anything, as long as she had sheet music.  She never understood how I could play without music, or without memorizing the notes.  She was proud of me though and I was equally proud of her.
I just hijacked my own post.  Or re-jacked it.
