One of my cats plays the piano ...
... sometimes. I.e. walks around on the keyboard. The other one never does.
My pianist cat also appears to enjoy classical music; whenever I lisen to something, he listens too. The other one doesn't like music at all; whenever I play some music she goes in the other room to take a nap.
This may all sound completely irrelevant and off-topic, but I don't believe it is.
The pianist cat has been doing this for a number of years, so I can reasonably conclude that (a) he is aware of what he is doing and (b) he derives some enjoyment out of it. At a minimum, I can't attribute to accident his jumping on the piano chair, then on the keyboard, then making piano sounds.
So, two questions:
1. If I recorded my pianist cat while he's playing, would that recording be considered an original work, and, if so, would it be subject to copyright?
2. If this recording is indeed an original work and is subject to copyright, who owns the copyright? I don't believe I own it, I didn't create these piano sounds, my cat did. I only recorded the sounds. Same exact thing as a recording engineer: Deutsche Grammophon's recording engineer doesn't own the copyrights to Maurizio Pollini's recording; it's Pollini and Deutsche Grammophon who own the copyrights.
In my view, my cat's recordings - if they existed - aren't copyrightable at all. I would have a very difficult time arguing that my cat is a pianist. I can't really see how Mr. Slater can reasonably argue that the monkey who took a selfie is a photographer.
