Violinist Holly Mulcahy recently sent me a link to this new, even cuter video featuring Nora the cat playing the piano. You can click here for the original video. The startling thing about these videos is how obviously Nora enjoys playing the piano. She is definitely communicating with humans through the instrument.
Also, she really likes major 2nds, and she really likes white keys. No pentatonic scales for Nora, I guess.
