The emergence exhibition · part three
Six voices, and the same three rules the birds fly by — sung instead of flown. Nobody wrote this melody. Nobody is writing it now.
Never sing the note a neighbor is singing. Off, and the six voices collapse toward unison.
Rise when the others rise, fall when they fall. Off, and the shared contour dissolves into six random walks.
Drift back toward the ensemble's center. Off, and the voices scatter to the edges of their range.
This is the murmuration again, note for bird. Each voice follows its neighbors in pitch space exactly the way a starling follows its neighbors in air: don't crowd (so no two voices land on the same note), align (so the ensemble rises and falls together), cohere (so nobody wanders off the register). The lines above are the flock; your ears are watching it.
What you hear that was never specified: call-and-response, voices trading places, long swells where the whole choir climbs together and then thinks better of it. The counterpoint is nobody's intention — it is what three small courtesies sound like when six singers extend them to each other several times a second.
