What do you mean when you say Chopin is educational?There is no essential repetoire.
Sorabji is crucial to the development of a young musician.
For a beginner, Clementi's sonatinas are useful (and nice).
A Mozart sonata surely?After learning one this last year i feel i've learnt a hell of alot from it - in terms of technique/style/touch (- mainly how to play lightly which i found particulary difficult)/sound - all things i can apply to many other pieces. I found the Mozart (K576 it was) took me longer to learn than Beethoven's Les Adieux which i started 3 weeks ago, Mozart is defintely a real challenge. I have more respect for his music than ever these days.
who the *** would want to play the same *** as everyone else?
