Correct fingering comes mostly with classical trained keyboard players...

But since many of them never learned to play what they feel, but try to play whats written in sheetmusic, they often sound less naturall then selftought players..

Current teaching methods try and learn our youngsters both, play sheet music with correct fingering, while also playing based on their feelings, with no sheetmusic but still using correct fingering.. i.e. one day they are playing Chopin from sheetmusic, while the other day they are improvising on a Bluess mellody witouth any sheets or notes..
