Hi I just wanted to know if you could recommend a piece by Liszt that develops technique. I am in the intermediate level, I can play Beethoven sonata op 14 no 1, 3 movement, Beethoven sonata op 10 no 2 1st mov and Bach prelude 2 and clair de lune. I don't want something crazy hard like la Campanella but I do want something to get me started, what would you recommend?
