Pumpkin and his Nemesis

I joined a group that gets together once a month to play chamber music, so I have to start practicing before our first meetup. It doesn't seem to bother Giselle very much, but Pumpkin sits a few feet away and quietly meows at me while I play -- especially when I'm playing notes that are on the high side. I guess that doesn't mean he doesn't like it; maybe he is a musical cat. Since he doesn't hate the object itself I thought it would make a good stuff-on-my-cat photo. He does look a little annoyed though.
