I've been working on this piece for a while now, and have gotten to the point where I can get through it from beginning to end all right, but there are a couple sections that I can't really seem to get under my fingers. One in particular is the left hand in mm. 22-23, where I'm still trying to figure out the best fingering to use.I've seen some references online that suggest doing each group of notes straight through, with no finger crossings (543212345). This seems extremely awkward to me, especially because on some of the groups 4 and 3 are stuck in between some black keys in a tricky way. I've tried crossing over 2 and 3 on a couple of the groups (541323145), and this feels a bit more natural to me, but when playing it at speed it starts to feel kind of fluttery and uneven.Does anybody have any suggestions on this part? Should I just buck up and do some more finger stretches, and get used to doing them all straight? Or does some combination of crossings work better for those who have played this piece? I'd love to hear any suggestions.
