Halftone
Hour

One hour of light on a small hill — a radio mast, a house, a sun that refuses to stay put. Printed in three ink pairs, each with its own registration drift.

Gloaming

The score

Every note is a free instrument sample from the University of Iowa Musical Instrument Samples — free to use in any project, without restriction. Sliced from chromatic scale files, then arranged at 66 BPM.

Marimba

Yarn mallets, mid register. The motif — A C E G, wandering.

Vibraphone

Sustain and bow. The bed the hour floats on.

Crotales

One hit at every turn of the light. C6 at the title, C7 at night.

Cello

Pizzicato pulse on the hill. C2 when the day is heavy.

Flute

A single non-vibrato line through the weather front.

Process notes

Riso logic. Three spot inks, printed one plate at a time. Each plate is a coverage field that becomes a halftone dot screen — line art (the mast, the pulses, the stars) skips the screen so hairlines survive. Registration drifts a couple of pixels per plate per frame, because a press never sits perfectly still.

One cut, three hours. The sun path, the night and the grain seed change per edition. Dawn gets a long day; gloaming loses the sun halfway through. Same house, same mast, same hills.

Film grain. Paper fibre, ink mottle, and a 1.2% gate flicker at 31 Hz. 24 fps, 960×540, 1,680 frames a pass.
