practice it hands separately and you will find out which are the hardest sections for you .
IMHO, the left hand is pretty ruthless at-
just after rehearsal 10, 'Tempo Precendete ma un poco piu mosso'
piu vivo at the bottom of pg. 17 to pg. 18.
Althoguh both of these are patterns will eventually come, I recommend slow practice, with extreme examination at, and away from the piano - be aware of your hands every momvement in these sections and what works cuz they are quite awkward, and have a habit of forgetting themselves.
hmm, and also it is very difficult in general . There is a reason people say "OOOOOOH RACHHHH 3"
other advice:
- Don't do the ossia cadenza unless you really want to. Learn the whole work, if that is your intention, and perhaps learn it then. Or learn it now whatever.
-Try not to imitate Horowitz.
-STAY ENTHUSIASTIC and BE VERY PATIENT
-Also listen to Rach himself play it if you already haven't.
uhm, ya.
