twocats Trying to memorize the first notes of each section away from the piano isn't working. I think creating the chunks and analyzing the structure of the piece is okay to do away from the piano, but I need to actually play the sections to memorize them!
I kept thinking about this after reading it yesterday. First thought was "Why would one?" 2nd thought was "How would one?" I supposed the "why" is probably in advice, maybe from the pianist video (admittedly I skipped through)
For the "how" I was immediately back to what I wrote earlier - the overall musical form of the piece, the overview before starting. Having a map and having context. The first notes of a section. Your section will be in a key. Maybe it modulated - so the new key is being established - either through the I chord or the V chord. So if in your "broad map" of the piece, you know your now in the key of Bb your first chord might be Bb so the first notes might involve Bb, D, F - or the first chord is Eb so the first notes might be Eb G or (again) Bb. So - would the knowledge of what's going on in the music overall, the "place" of this section in particular - help you remember the first note of the section?
