Day 10: Harmonic plan for max satisfaction

In my recent big song cycle, Fiat Lux, there was a movement for solo sextet and electronics about the speed of light. The text I wrote was:

Immediacy in the known universe is illegal
There is no instant, recipients must wait
Waiting times vary, but the speed limit is constant
299792458

Metres per second, the speed of light
Though light rarely reaches this goal
Obstacles bend, reflect and refract
The limit's reserved for black holes

I was using the numerals as a source for pitch and rhythmic material in the work: scale degrees and note lengths. I wanted this really climactic, knock your socks off ending, but tbh it ended up a bit blue balls.

I'm now arranging the piece for solo sextet with SATB accompaniment and I'm having another crack at the end. Today I wrote out the harmonic plan. I plan to combine this with an accel. and very clear climactic signposting from the SATB accomp.
