What a great idea, AJ, and so generous!
Count on me, too. As limited as a “virtual” lesson can be, the tutorial videos you and Birba made for us have proven to be a precious help, a mine of useful suggestions one can apply in general, non only to a specific piece.
If you dont’ mind, I’ll start immediatly, submitting you a problem I’m vainly struggling with. Before giving up, I’ll size the chance you are so generously giving us.. (I hope you cand understand my awful English).
The piece is Prokofiev’s Suggestion diabolique. The section that is driving me crazy is the one after the introduction (bb. 27-51), with the fast repeated chords and the theme switching between LH and RH.
If I’ll be able to understand the right finger/hand/wrist motion for the first 4 bars, I think I have the key for the rest (but bb. 46-50 are a hell of their own).
First of all, there is no “staccato” mark, but the sound should be dry and light: how to play the theme? A "loose" legato, in order to avoid pedalling? And above all, how avoid tension and gain accuracy and speed?
2) What is the best fingering for the chords (considering that I’ve small hands)?
My score gives the following fingering for the chords in bars 27- 28: 542, 532, 421, but the leap from D (5) to the next chord (421) , which is supposed to be “legato”, is troublesome for me.
Sorry if I dont’ allegate a score (you can download it for free from IMSLP site).
I hope you won't regret your proposal after my post

I’ll understand if you won’t answer to my questions. I’ll be grateful to you nonetheless, and I’m sure I’ll benefit from all the suggestions you’ll give to other forumeers.
I whish you all the best

Thank you again
