So I have been playing with this étude* on and off for about ten years. I have to play it for a jury of my school's piano faculty a week from tomorrow, and I've been having trouble with some bits of it. In particular, the upward chromatic thingies for each individual variation of the theme have had me confused. I know the fingerings, but I've been viewing them as separate things to learn, and though in some ways they are, they're essentially the same thing in the parts that have been screwing me up (the middles of the runs). So, I just realized tonight that it's all the same fingering. I know the differences between them, and have no problem playing them, but I didn't realize before that it's all the same conventional chromatic thirds fingering in the middle. The thumb skips from E to F and from B to C (or backwards on the way down), and once you get the hang of the chromatic thirds, that's the only thing you need to pay attention to - that skipping thumb. I feel like an idiot now for not realizing this before. I had only paid special attention to the skipping thumb in the final descending chromatic thirds before, perhaps because it was descending and therefore more evident to me? I don't know. I'm just happy that 90% of my technique difficulties with this piece have finally gone away. *In case anyone was wondering: yes, using "special characters" makes me feel special.
