I'm saying is, give Mozart a little respect. He wrote some wonderful piano repertoire; the sonata for 2 pianos is one of my favorite pieces of all time. You can't just discredit his entire piano repertoire based on a few of his sonatas, and whether you like them or not is a personal taste in the first place.
As for your argument that I am stupid for saying 4 year olds don't play Mozart well, it has much more merit than your remark that they do play well. Its like saying 4 year olds play any legitimate concert repertoire such as Bach, Haydn, Beethoven, Chopin, Liszt, Schumann, Brahms, Rachmaninoff, Debussy, Ravel, Prokofiev, Scriabin, shall I go on?) well. As for "Korean" 4 year olds, why not chinese or japanese or even white 4 year olds? I don't understand why you singled out Koreans as playing Mozart well.
As for evidence, what evidence do I need? The lack of 4 year olds who play Mozart well is quite good evidence. I will take back what I said if you can find me a 4 year old KOREAN girl who can play Mozart well.
And your rant about calling me stupid was a bit unnecessary. I got the point already with the first sentence.
I will take back what I said that most pianists avoid Mozart, and college kids (I mean conservatory students) don't play Mozart well, concert pianists avoiding Mozart, etc. They don't, but that's because they have the experience needed to play this difficult repertoire. Yes I know, Debussy requires just as much control and maturity as Mozart, as does Ravel. I was exaggerating to fit my words.
But you seem to have the assumption that Mozart is easy to play. It is very exposed, there's no pedal to hide behind, no thick textures to cover up mistakes. If Mozart could be summed up in one word, it would be perfection. His pieces require a perfection (using this word loosely, since nothing in the world is perfect) as a minimum for the standard in which is acceptable to perform.
And you haven't explained how Mozart is any less difficult than Liszt. You talk as if you are above playing Mozart which in my opinion anyone who thinks they are above playing Mozart is either ignorant or in denial.
