Thanks, David. Out of twelve, the first one was the 5th take, the second the 11th take, and the third the 6th take. I don't listen to the recording until I get home and hear everything in bulk, but I have spoken cues after the first here, "Best one yet, I think." And the one both you and j_menz picked, "Almost, almost, almost perfect!" as if in a bit of despair. It is one stretch of a 9th in the right hand before the recap that my little span caught the D-flat with the C. But as for the success of the recordings, it seems something starts to click midway through, and a new plateau is reached, and then for either concentration or some other reason, it unravels and I descend back down the hill. This is an interesting pattern to study.
Alas, there are so many layers in Godowsky's music, and how impossible to grasp them and hold them in balance!
