Hi, i need to choose 2 rach preludes. i have chosen 1 so far (op32no.5). Seeing as this is a slow and beautiful one, i was hoping to find a more contrasting one (fast and not so beautiful

). Is it necessary to choose one from the op23, seeing as i have chosen one from op32? im looking for the more short works, so nothing over 4 or 5 minutes. can anyone help me here?
my recent rep:
Liszt - Jeux d'eau a la villa d'Este
Debusy: Images - Reflet dans l'eau
Estampes- Jardin sous la pluie
Etude - Pour les cinq doits
Chopin Etudes 25/1 and 10/7
My suggested repetoire for the near future is:
Ravel - Ondine
Bach Concerto in Dminor 1st mvt
Liszt - St Francois de Paule from Deux Legendes
I hope this gives you an idea of what i could do from Rach preludes. My teacher has only given a time limit (ie. learning short pieces, because i am learning on my own for a month or two), but he seems to think that none of them should be problem, technically, but i dont want a mammoth of a piece because i have to get this and lots of other rep ready for auditions in november.
Thanks for reading,
