Ma·tins
A procedural dawn chorus

Matins

Four birds you have never heard before. None of them recorded — every note built the instant it sounds, while the sky warms from pre-dawn to full morning.

01The score

Nobody sampled a single bird. Each voice is arithmetic — oscillators, a little frequency modulation, and short bursts of filtered noise.

Birdsong is mostly pure tone with fast pitch glides and a hard percussive edge, which is exactly what a synthesiser is good at. Below are the four instruments MATINS carries, and how each one is drawn from silence.

02Field notes

The dawn chorus is a queue, not a crowd. The birds with the largest eyes sing first, in light too dim for the sparrowhawk to hunt by. MATINS keeps that order: the blackbird opens alone in the dark, and the hedge fills in only as the horizon reddens.

What advances
Sixty real seconds carry the sky from nautical dawn to full morning. Voices join at fixed light-levels, not fixed times — pause, and the queue waits with you.
Second listen
Every spark of light in the sky sits at the exact stereo position of the note that made it. Watch the left tree while the blackbird sings.
Once in a while
When the light is fully up, listen past the hedge. Something two-note and far off answers, perhaps one dawn in six.
