The Rach 3 has a billion more notes in it, and they're scattered everywhere. The Busoni has many scaler runs.
EXACTLY. Can you believe the RACH3 strikes ALL the 88 KEYS (from the lowest A to the highest C)! (Striking the lowest A is already common but it's very SELDOM a piece would include the highest C note ever.)
Err... if it is concerto number 11 in D Major, for the sheets I would suggest you look, erm, well, where could you look, hmm, a piano sheet site? Yeah, well, I have heard of one, err, how was it called, err, darn, what was it, something with Piano, Piano Sheet, no Street? Piano Street? Hehe, sorry...https://www.pianostreet.com/search/searchsimple.php?composer=17&limit=15
The easiest are Mozart´s num 21 or Haynd´s.Ignaz Moscheles worte very very difficult concertos but unfortunately they are underrated.
I'd definitely consider Mozart's no 21 one of the more difficult Mozart concertos.Have you tried the others?
Actually I've heard that Liszt's No. 1 is rather easy.
how about mendelssohn 1?
I have tried to play thousands and failed with all but two and both were by Martines, so they must be the easiest and the most difficult all the rest.The Moses Pergament Piano Concerto looks insane, but no doubt so are several hundreds of other plinkers.
forget the concerto for now and have a look (or, better still, a listen) to some of his string quartets;
