Im 14 and ive been playing piano for 11 months. OF course i have a teacher and she`s proud of me. Anyway, for me, Franz Liszt`s Hungurian Rhapsody no.2 is the hardest piano piece ever. The only way to do this is to practice 1 page in 1, 2 or 3 days and to memorize it. So far, the hardest piece ive ever played is Frederic Chopin`s Polonaise op.53. Thats it!
