I just got done watching "Human Error" (http://en.wikipedia.org/wiki/Human_Error_%28Star_Trek:_Voyager%29) from S7. During the episode, Seven is playing the piano for Chakotay (simulation) on the holodeck and he asks her to play a piece he says is his favorite. He then turns off the metronome and tells her to put more emotion into it and feel the music and that it doesn't have to be perfect. My question is: does anyone know what that particular piano piece is?
