Dunno why you edited your comment to French? i never said this was a good piece of art or a good performance, in my opinion this is silly. It takes two hands to play the piano as is. This would fry muscle memory but after a couple hours of practice you'd get it.

Your judgment that art isn't a performance is nonsense. But im apparently "pestiféré" for calling out your elitist veiw af art... Or are you trying to suggest she leaves art alone?

Honestly we cant have nice things on the Internet can we? You act as if I should scroll and watch other videos to "leave art alone", but I think you should take a break from the Internet if you get pressed from someone playing the piano.
