I heard that the storm prelude is waaaay difficult than it sounds, that's why I hesitate to start on this piece (I don't like pieces that are extremely hard but sound very easy).....how does it compare to the chopin etudes listed above?
My experience: Chopin 28/24 is not so difficult if you can use the "secret" fingering. The "secret" fingering might be "illegal" by Czerny standards, though. It's just to finger the right hand's upward runs by having their uppermost note be on finger 5; then going backwards, finger 4, 3, 2, 1, 5, 4, 3, 2, 1, 5, 4, 3, 2, 1, and so on. At a slow speed this would sound too "choppy", but at a high speed, it fits together.
