What exactly do you mean by the "hard' concerti? At the level of Rachmaninov/Prokofiev/Liszt/Tchaikovsky or including stuff like Grieg/Mendelssohn or what? It makes a difference...
Rachmaninov's Rhapsody on a theme of Paganini progresses through a sort of theme and variations idea (which might be easier to learn - yet HARD as you asked). just an idea. it's a theme and 24 variations.
Rach 3... do what everone else was thinking.. and get a proffesional orchestra... If you are 8 years old, you may become a pro...
You are right, I really would be bored with a Mozart concerto. But the rhapsody on a theme by paganini! Amazing. If it really isn't too much of a problem to perform, I would really go with this one. Anyone second that idea?
How about one of the 2 Liszt? No synchronization problems there...easy to put together with somebody - one rehearsal should do it.
what about the schumann concerto?
Actually the Liszt Concerti are especially difficult to synchronize because of all the tempo markings. In the 2nd concerto alone the tempo changes 7 or 8 times (maybe more). The 2nd concerto is a beast to get all the tempo changes down. I would recomend the Ravel Left Hand Concerto. It's pretty straight forward in terms of synchronization.SAM
Yes, many tempo changes, but in almost all of the changes, one player precedes the other, in other words, it is always easy for the accompanist to follow the soloist's tempi, and vice-versa, because they don't begin simultaneously. Of course, there are a couple of places where both change simultaneously, especially in the 2nd, but even those are generally easy to follow.
