Does anyone have any suggestions for fingering and for practicing the scale-run at measure 228 in Scarbo? I am working on all three movements and have had particular trouble with this quick run. I cannot seem to get that fast, effortless, continuous stream of notes down. As it descends the keys, I am fine and can go fairly quickly. But, the trouble is doing that 5 against 3 arpeggio that ascends to the high keys. I can't get that wet and intense sound in the bottom notes to contrast with a delicate and dry top notes. I know one of the answers is practice, but I'm trying to make my practice more efficient. Same question goes for a similar run in measure 253.
Lastly, does anyone have fingering suggestions for the majors seconds in measure 460? I have actually been using my thumb to play two white notes and my second and third finger to play the black notes. Thoughts?
