Q: Who is performing? A: This recording is by the Charmillon Piano Quartet; its members are Etienne Abelin, violin, Michael Schwendimann, viola, Matthias Kuhn, violoncello, and Eva-Maria Zimmermann, piano.
Q: You already posted this video; why are you posting it again? A: Etienne Abelin gave me permission to use this recording in a video, and it was a better performance than the one I'd been using before. Also, I thought it was a good piece to submit to the "YouTube Play" program, and I wanted to give it my best shot. Wish us luck!
Q: Is there a way I could make this kind of animation myself? A: The Music Animation Machine MIDI file player will generate this kind of display; you can get the (Windows) software here: http://www.musanim.com/player/ There are lots of places on the web where you can get MIDI files; I usually go to the Classical Archives site first: http://www.classicalarchives.com/
