Piece for building speed, fluency, and control?

[sharmayelverton]

Title speaks for itself! lol. What pieces can you guys recommend that will build speed, fluency and control so as to be able to play for example, pieces such as Beethoven's Appassionata third mv or Rachmaninoff Prelude Op.23 No.7, or well anything with fast and delicate continuous semiquavers?

These particular pieces are a bit beyond me at the moment so need some more intermediate stages. I've played CPE Bach's solfeggietto. I'm not terribly in favor of playing Czerny, unless someone wants to really argue the case otherwise, but would much rather find pieces in the repertoire with their own compositional merit. I'm also already practicing scales and pure technique in this vein but could definitely use some good motivating pieces in within my grasp to keep polishing this stuff!

Thanks as always guys!

Maybe you dont like it, but Czerny is great for improving exactly that.

Well it's not that I'm unwilling to play technical exercises, it's also that I need to build up my repertoire as I have so little. As it is I spend most of my practice playing scales and stuff and very little learning new pieces. I'll play some Czerny, certainly, what ones do you recommend? Still I would very much like to find stuff in repertoire as well.
