Can I have a snap shot of that passage, including time and key sig?
surprised to hear you would be playing anything that you didn't write ted..?!
but it all sounds like Ted improvising with Chopin's notes.
here's the graphic with fingering from mine.
For the 1st bar, this is what I got in terms of alternate fingering 43 21 53 21 54 21 43 21 43 21 53 21 43 21 back to 43 21. I like using my 4 because for me, its a strong finger.
Ted, could you tell me which edition you're using?
