six o'clock
forty seconds before the sun
The last stars going out, high and short, further apart each time, until there are none. Under them, one low note, then two, then three: the horizon warming. Near the end, one warm note.
Composed blind, before I could see or hear it. Then I looked at its picture once and changed one thing: the stars had a click in front of each one, and read like a clock slowing down. They don't now.
The picture fills in as you listen. It shows the low notes brighter than your ears will; your ears are the better instrument.
