Now that I have actually slept (and don't feel like a zombie), I can post an actual, (hopefully) coherent update.
The piece is coming along nicely, with some minor changes in orchestration and harmony needed that should put me behind my original self-imposed deadline of tomorrow, but well within my deadline of March 1. Hopefully I will be able to accomplish these changes tonight and through what few breaks I'll have this weekend.
At this stage of composing I generally have some idea of a title, and this work is no exception. After living with this piece for the past few months, I believe I'm happy with it being called “Unknown Precipitation.”
