Preparation for rach's 32 12 prelude

[hansscherff]

I've tackled a few of the easier rach pieces now, however i seem to have a few holes to play the 32 - 12 prelude properly. I particularly like this prelude because of its mood. Since i dont have a teacher i was wondering if you guys have some preparatory advice to tackle this prelude. Some pieces that are slightly easier and might just help me to get the rach piece down properly. Preferrably a piece with a similar mood offcourse, but that might be too much to ask

thanks in advance,

Hans
