I mean, the piano, of course, but I think the piano should be taught in school just like mathematics, just like reading, writing and arithmetic. I'd say reading, writing, arithmetic and rhythm. But that should be a prerequisite, because then the quality of music in the world at least in the United States, would be much better, if everyone knew something about the piano and about music, they would know this is not good. Right now, there is so much music out that's not good, but no one knows the public doesn't know.
