@@pradolarayaelalejandro1542 I agree. Learned both Chopin etude op 10 no 3 and this czerny etude and czerny was way harder. Playing this with no mistake and in tempo is just insane. Still can't play Czerny yet and it will surely take me the next couple of months to finish it. Chopin wasn't easy but easier than mastering that etude.
Practice. Tip: just repeat octaves as fast as you can and as long you can. Then repeat that every consecutive day you practice. Then you won’t get tired anymore :)
Learn this etude, but start very slow. Always keep your wrist loose while playing octaves, and you'll eventually be able to play loosely and relaxed in quite a fast tempo.
