Cat learns piano in cutest duet ever

Sam Friedman, a pianist based in Los Angeles, is attempting the impressive feat of teaching his cat piano.

In the footage, Sam plays, encouraging his cat to make a contribution. "In this video we are working on improvising duets," he says.

"I try to teach with very positive reinforcement. He's still a beginner, but he's very passionate and purrs a lot whenever he sits down to play."

The footage was shot in December last year.
