I don't have bar numbers marked in mine (Augener) and I've probably miscounted. I don't have the score to hand, but its the growly RH bit in the base, which recurs once. Although I'm religiously observing the marked fingering (not one of my strong points), I seem to have come to a bit of a speed limit (and its only about half speed!). I'm also having (unusual) trouble getting the long RH descent following, which runs into the allegro recap.
It all needs much more practice, but any tips would be welcome.
(I'll try a recount of the bars if its not obvious from the above)
I know the bit you mean. Like most pianistic difficulties it yields quickly to practicing slowly for a few days after resisting for months all attempts to force the pace. When the fingers know exactly where they are going, and the mind can think through the sound at the target speed then the speed will come.
The fingering: 2532 1542 1532 1531 works well enough
Points for attention are:
Clear articulation giving attention to each separate note
LH and RH precisely together
Even though it seems "growly" aim to produce an attractive even tone. The "growliness" comes from the various discords in the RH over the repeated G in the bass
Observe the line in the bottom notes of the RH figures Csharp-D-C-B
Note the resolution of tension from C-Eb-Ab to the E-D-G (G major chord) in the RH
The passage makes a nice loop, so it easy to practice over and over again.
Isn't it a wonderful piece - however hackneyed it might be.
