My music teacher is amazing. Over Zoom, with three timezones and one national border between us, she was able to hear that I was misplaying this E-doubling.
To play the F grace note, I should have been raising the middle finger on my top hand, NOT my index finger (that's a G grace note).
Gotta re-program my brain on that one. It sounds more musical correctly played IMO, so at least I'm not fighting my tin ear over this fix.

Yes!
No background image or blurring of the background either. Otherwise, my fingering can get distorted.
I feel very lucky to have found a good teacher.
