I've got a few questions about Chopin Polonaise Op 40 Nr 1
1). For the descending trills area (shown in attachments), is that the right fingering? is there anything else more optimal? and i'm thinking of trilling 4 keys for each tr. is that right?
2) The first trill sequence where it shows fingers 3,1 for both the left and right hand imply a trill that has opposing key strikes - one is up while the other is down. Is that correct? and for the following two trill sections that are similar.
3) Also, is the fingering I've marked up, optimal?
Also, any other advice you have on playing this piece would help.
Thanks!
