Waldstein Sonata 1st movt vs Chopin's gmin ballade #1. Which one is more difficult in ur opinion?
Musically... that would depend on your personality.
im trying to learn the waldstein 1 but im working on rach op 23 no 5, pathetique, beethoven op 2 no 3 mvt 1, debussy mouvement from images 2, and brahms rhapsody in g minor op 72 no 2 all at the same time so its not coming along so well
