And it’s important that she plays the viola! Viola players are usually joked about as being dumb - you couldn’t tell the joke about say a flutist… .
One of my ex-boyfriends played the viola and he loved to tell these jokes. 
Playing the piano does not really lend itself well to names, especially with my setup. My mom has her grandmother’s piano in our house. At school, I have a wimpy little 48-key MIDI hooked up to my PC, or I can sneak into the music department’s practice rooms late at night. There’s not much point in naming any of them since I don’t really have one I would be that attached to.

I don’t play an instrument, but I have a good friend with a cello named Consuela.
