Advice for fingering on a Mozart trill

[dss62467]

My teacher talked me into playing at the upcoming recital, since none of his adult students ever dare do it.  We're doing a Mozart violin sonata (violin/piano duet), but he asked if I would do a solo piece too.  I'm brushing up on Mozart K330, which I haven't played for him in months, and I noticed while playing it last night that my trills in a couple spots are pretty lame.

If you take a look at the sheet music, on the 3rd page, measure 72, there's a B-flat trill, that just seems to go nowhere when I play it.   What would be a good fingering choice for that?  I think I'm using 2-3, since that will allow me to move to the next part efficiently.    When I trill with a black key, I usually have a bit of trouble.

For black key trills, I almost always use 1-3. They are strong fingers and if you use 2-3 your fingers will not move very fast. That is not a standard fingering. It will be hard to move your wrist around if you fingers are flying back and forth. Use 1-3 and tilt your wrist to each finger so that you aren't just hitting the key.
Let me know if this works.

I'm not a gold member, so I can't access the score you refer to.  But if the trill ends in a nachschlag (A-B♭) as in this edition of Lebert and Scharfenberg at IMSLP, you should try to stick to 2-3 and execute it as shown in the footnote:



Any fingering for the trill that doesn't allow you to end it gracefully is a recipe for stumbling or grinding to a halt when you get the last two notes.  (And even if there were no nachschlag, the first note of the next measure is an A; if you trilled with 1-3, what finger would you use on the A?)

Hey!  Thanks Steve!  I didn't even know about that site.  It suggests 2-3, so I guess my task is to work on executing that trill.   I've got a couple weeks.   I know the piece well, so that should be enough time.... or I can just pretend I'm sick and can only do the violin sonata. 

Thanks, Biscuit - I would try the 1-3 combo if I didn't need the 1 for the A.   I need more fingers.

LOL - I'm practicing these stinking trills right now and noticed something amusing.... I clench my teeth when I trill.   Something tells me that indicates I don't relax enough.... what do you think?

Mozart was a sadistic little wig wearing man.
