It is a Debussy Prelude, a "stretch piece" for me atm, Book One, no. IV (the "sounds and perfumes" one). We're m. 29 & 30, just after he's slipped temporarily into Ab from A.
If you've played the piece before, then you'll know how you memorized this section, and might still be able to play it now from memory now or after a short jog. If you haven't, it would be interesting to see what you run into. (I haven't stated referencing for myself where it is within the overall structure/form of the piece when I play it because that can be taken for granted.)
I haven't gone near it for over a week, and it was there for me just now, but NOT as "muscle memory". I drew on the things that I listed - types of chords, chromatic descent for the LH etc. This is my first time with this kind of music. I'm much more home with Common Practice, which is also more predictable.
I'm thinking that in terms of giving names to individual notes, isn't calling something a Gdim7, or Dbm, also a name? Isn't a chord itself a "thing"? Obviously they live in context. In fact the individual notes, which wkmt was highlighting as being named, are also sitting in context - tonic going to tonic within the passage; relating to the chord etc. But he was talking about name notes. In this passage, naming chords, rather than a passle of notes within the chord, was more effective for me.
Anyway, interested in what you have to say. (Wkmt so far has not written back).
