Yes it is an Etude but also a lot more. It is more important to play it cleanly and beautifully than with the correct hand.
If i was playing Czerny or Cramer etudes, i would never cheat.
I agree. But also, I believe that we should take all advantages that we can from the music, a great piece, and also a great technical study to improve flexibility, accuracy, and stamina and give an introduction to the Lisztian technical and musical world. But since this is not pure technique, I certainly agree with thalbergmad.
After starting to learn the piano on my own without the help of the piano teacher, i decided to learn La Campanella, just curious about 1 question
For the Treble Staff, do you play all the notes only with right hand (that's such a big leap) or split some into left hand
I also learned to play piano by myself for 3 years now, and I have not yet finished practicing La Campanella. But, one advice, don't worry that much about the big leaps, they are actually not that hard after you practice and examine those passages. Shouldn't take too long to get used to the jumping hand and moving arm. The only thing, the hand has to jump, there is no need to stretch the hand that wide.
Enjoy practice.
