I'm playing the prestissimo movement from Beethoven's sonata in F minor op.2. I think I've made a mistake in playing it separately in three sections because when I put it all together I can't get through it without feeling intense fatigue.

The middle section doesn't include these triplet figures in the bass so I can use that to rest my wrists.

I intent to slow it down to a reasonable pace when I can play right through without fatigue...But what happens then? Do I gradually speed it up again or just jump straight in there?

Tips greatly appreciated.

This is a great movement to rattle through. I have been playing it for over 40 years , and still find it quite a tiring movement to play. Of course Prestissimo means 'as fast as possible', and this can be different from person to person, but its no good playing at at a leisurly Allegro. Firstly I assume you are not doing the repeat, its not necessary, it would just make things worse if you do, though I get through it almost exactly 5 mins with repeat, so its not that long! How to over come the fatigue is not so easy,. I assume its just in your left wrist. Suggest you try to stengthen your left wrist by spending a few minutes each day squeezing, holding a few seconds then releasing a tennis ball or similar. But dont overdo it. Otherwise you're just going to have to play it a a speed thats comfortable. At least you get a rest in the middle section, but dont slow down, its still prestissimo. (Another tip, if you dont already, split the final downward arpeggio between two hands in three parts ( ie right hand, left hand, the right hand over) , its easy to foul it up otherwise.

Aha, something I recently discovered after sweating over it with jerky wrist for a few months!

Thanks for your response.
