I love this part because it looks harder than it actually is. As long as you keep a supple, loose wrist, and active pointy fingertips, this will just fly. When I play it, I am careful to note Chopin’s marking “accelerando a fin” or in other words, from here on out get faster and faster until the end. It is important to not go SO fast right away lest you end up with a train-wreck ending. At the same time, I like to immediately halt the tempo here, along with dropping the dynamics down to a hushed pianissimo, so that the impending accelerando plus the crescendo makes for a most effective and satisfying ending.
