Chopin wrote a rhapsody

Liszt Rhapsody no 2 - Preparatory Pieces?

involved since
Dec 13, 2009

Like many, I have long set myself a goal, for me it is Liszt's second rhapsody.
For a long time I have been marveling at the pianists who can play this piece and I am totally fascinated by the two "themes" Lassan and Friska.
I know that there is still a long way to go, but I would like to prepare myself well for the difficulties that this rhapsody has to offer.

I played the first movement of Beethoven's "Pathetique" sonata (with the first piece where I sat a little longer), Nocturne 20 (a) by Chopin, Bach Symphony 11, Alla Turca (a long time ago) and many more Burgmüller and Czerny as well as smaller pieces.
Then two weeks ago I made the jump to one
Chopin Etude op.10 no 1 daring
(yeah, it's damn hard to get them clean).
Only that you can roughly estimate my current status.

What difficulties does this great work present?
And above all, which pieces would you suggest to be able to master them?
I know that remote diagnosis is difficult, but I would still be very interested in which pieces you would suggest.
For the jumps (e.g. in "Tempo giusto - vivace") I would have thought of Chopin's waltzes, for example.

As always, I'm really looking forward to answers.
best regards
