You have done a great job. It is mind blowing to hear ordinary pianist to play such as high demanding pieces. I always watch and hear the top notch pianists to conquer this sort of music. (You are properly not that ordinary after all).
I am in diploma level, but I haven't tempted to play some of the high demanding etudes yet. The one I am working on op10 #3. This one compare to the ones you play is far from it. Just a question. In what point that you think you can master it? Do you start working out note by note, with separate hand practice with slow speed. How do you practice it? Could you tell us? I love to know, and my problem to play any chopin Etude, my hands are very small, just enough to reach to octave. Etude op 10 #3 in the middle part of the both 6 intervals double notes are the killer for me. I can't reach them quicker enough, and always hit the wrong note. Do you have any suggestion? How can I solve this physical side of problem? Thank you for posting this lovely concert, really enjoy and hope you can do some more in the future.
