....I'm trilling on 2 and 4 because even though my edition suggests trilling on 3 and 5 I simply can't do that fast enough and I don't want to make things unnecessarily difficult for myself.
Of course! IMO 3-5 is completely and utterly ridiculous. I know that the people who do editions are supposedly experts, but.....all I can say is "but."
3-5 is completely ridiculous.
I'll try using 3 on the D# and C#....
Oh OK -- so that means you WERE using 2?
That might well be your main problem with the passage.
....the only reason this passage is difficult for me is because I'm trilling with 2 and 4 and so the only finger left for the C-natural is the thumb....
Not so! You can slide the 2nd finger onto the C.And even if you use the thumb
, which is what I would do anyway....
....and following that there's no fingers left for the remaining flourish.
Sure there are!! You can easily 'slide' the thumb from C to B, especially because (IMO) the desired articulations leave plenty of time for it.
You've been making it harder than it really is with (a) a bad fingering, and (b) some wrong assumptions.
I'd bet you'll now be able to play it quite well pretty soon.
