I think it sounds tighter and it's really the best way to play it comfortably at tempo (there isn't enough time for too many notes in the trill) A turn make the music flow unimpeded.
Likewise in the left hand i just do (G#(16), A(16), G#(16), F#(32), G#(32) | A) at tempo this sounds like a great trill
for me it doesn't sound right just doing a turn but maybe it's because i have already put in hundreds of hours of practicing these few measures as a trill and generally hate simplifying a score to make it easier. ur right, there isn't enough time to time to play too many notes in a trill. i used to add 2 more notes to the trill but when i listened back to it it sounded bad.
i wish it weren't so much more difficult to add those two extra notes to make the turn into a trill. i have listened to a bunch of professional recordings where they don't execute the right hand trills cleanly.
also, there are several other spots where you have to fit a trill into a short space, at those times do u do a turn as well? i do all those trills in a similar way that i described the other trills i do. like i play 2 notes then do a turn. i think it's the minimum amount to make it a trill.
is there anyone else here who has learned this piece that can offer input about how they play it or how they learned it?
PS: im playing this piece for an upcoming recital. how do u think i should handle the repeats or should i even repeat it at all? for me there are 2 sections. sometimes people repeat both of them, sometimes people just repeat the first part and then play till completion. what do u think?
