I saw YAP's thread on trills. I have a similiar problem.

Im studying Haydns Sonata Eb major hob.49 at the moment.

There are a couple of sections with trills. The edition im using suggests using demisemiquavers in the trill on top of a semiquaver left hand- This is very very fast but probably do-able. Triplets about the semiquavers sound the best, but i just couldnt manage to do it- tried and tried but could not get it. At the moment im just playing with semiquavers in the trill, with 2 demisemiquavers to finish the trill which then goes into a turn.

Does anyone who knows this piece have any advice for this section?
