Don't buy too much into classical mythology, pretty much anything is possible to play if you invest enough time into it, maybe not at a professional level but definitely possible.
Exactly.But what's professional? You can achieve anything you set your mind to, and therefore you can play any piece just as good as an international pianist. The thing is, if playing the piano is all you do, you might as well become a professional pianist then, since you need to devote most of your time for becoming that good.
Just like language you just learn it better when you're young
Were you a person who usually broke the odd? If not, do not expect too much with your musical life too
The time I spend on studying the piano isn't enough for becoming a great player even if I was very young because I only practice 1,5 - 2 hours a day, but this could get a little more when I start playing more lengthy pieces. I have no intentions of becoming a professional, but I would like to reach a level which allows me to play truly great music with joy and not having to say "Oh I can't play this" to huge parts of classical literature. Thanks for your encouragement!
in a recent student concert one played Schubert impromptu op 90 no 4 and another played claire de lune, both have been playing the piano for about 10 years.
"adagio, 40 quarter notes per second".
That's incredibly fast - is that what you meant to say?
You can see this isn't my day. Let me try one more time, and then I'll give up. "Forty quarter notesper minute".
