I tried to play Grace Kelly, Relax, Billy Brown and Happy ending by ear on the cello. It's very fun to do, but I don't know if I play it correct and I also play it slower because I have to think a lot
I'd love to play it on the piano, but I don't have one and I think it's more difficult when you don't have lessons and stuff and also because it's with both hands. But it's very cool when you can play that, also because the piano is in the song (and not the cello)
