Cartoon film about a boy who's piano plays itself (I think)
When I was a kid I had this cartoon film about a boy who was learning to play the piano and he wasn't doing very well at it. All of a sudden he got really good but (I think) it was because the piano was playing itself and in the end the boy had to do a piano recital and the piano wouldn't play for him. He kept trying to play and nothing would happen and then he woke up and the whole thing had been a dream. Given my age I think that I would have been watching the film sometime in the late 80s/early 90s. Does anyone have a clue what I'm talking about? I think the boy was playing Beethoven but I know it was definitely classical music and I know for definite that it's not Charlie Brown which keeps coming up every time I search for it in Google! Thanks!
