Beethoven Rondo a Capriccio, op. 129

[birba]

I had surgery done on my left arm about 6 months ago and it's been a long haul to get back to the piano. I still can't do jumps, but I've been taking up past repertoire to get the arm back to "normal" or thereabouts.  The Beethoven Rondo has helped with fast repeating chords besides keeping my right arm in shape.  I think it's one of Beethoven's more pianistic compositions and falls nicely under the hands.  BUT - beginning with the alberti bass variation at measure 126 - things fall apart.  The beginning jump of a 10th from g to b and the following jump of an 11th from g to c is impossible at the speed of a 160=quarter note.  I really don't know how I performed that years ago.  I can just imagine Argerich speeding through it like a piece of cake.  I've tried omitting that second 16th note, but it just doesn't sound right.  Can anyone give me some advice?!

although some people think that it is wastefull to stretch your hand, if you do that you wont have to move your forearm as much

Thanks...You just might have something there.  Will let you know.  I've been faking it up to now.

Is your wrist part of the surgery-spot? If it isn't, then you could use that instead of your arm. It works sometimes...

 I think I found the answer and I hope Beethoven accepts it as well.  I've changed the notes in the left hand.  I asked a pianist who performed it, and he changed the left hand to:
g-b-g-b-d-b-g-b (5-1-2-1-4-1-2-1)1and the other to g-c-f#-c-d-c-f#-c  Actually, I can get through the first one as it's written (stretching the hand as liordavid said instead of oscilating), but the second one I did change it, and you can barely notice the difference when you're playing at the right speed.  I know Arrau would say "horror of horrors", but it's a harmless little change that allows me to play this gem!
