Help with Mozart's Fanatasia in C Minor, K475: Piu Allegro

[abstractentity]

How do I get this section up to speed while not letting my hand get tired?  I've been working at for a week and a half and I still can't get it anywhere near the right speed.

relax relax relax (your hand of course)

Dont force the speed at all. I played this piece about a year ago and also had a bit of trouble with this section. Pretend this section is a nocturne or something and play it so slowly its just not funny and always relax. Enjoy the eveness of tone you will be getting and feel your hands being totally confident with it. Just get the muscle movements perfect by keeping it slow. Speed will come naturally and do not rush it at all.

All the best,
Rapmaster B.
