In Chopin's Waltz Op 43 No. 2 in A minor are some trills in the left hand. How many trills should be played in this bar and where to stop the trill, on E or on F?
Also since the right hand starts while we are still trilling with the left hand, on which note of the trill should we start with the right hand? For me it seems natural to end the trill on E because the next tone will be a D#, but then we have an odd numbers of trills if we start on E which does not work rhythmically?
Thank you for your answers.
