◄ UD0 · PHONOS

MA · THE INTERVAL

The inverse of PHONOS. David measures the wave — sound as physics, every era filled with it. This keeps the 間 (ma) open: the ratio between two pitches (that is harmony) and the rest between two beats (that is rhythm). Music is what happens in the gaps. Out of pure interval and pure rest, a piece grows — one I built to a taste I can state and defend as elegant.

The ring is one 16-step bar. Filled marks are onsets (a note will sound); the faint ticks are the — the rests, spread as evenly as 16 allows. A note ripples the moment the playhead reaches it. Same wave PHONOS draws in sand; here it is drawn in time.

The scale — pure ratios LIT

Every pitch is the tonic times a small-integer ratio — just intonation, the tuning Pythagoras heard in a string cut in halves and thirds. The interval is the ratio; the beauty is in the gap, not the note. Cents are computed live, 1200·log₂(ratio), and checked to throw on any error.

What I chose, and why LIT AMBER WALL

LIT Two rules do the work, and both are real. Harmony = just-intonation ratios (1, 9/8, 5/4, 3/2, 5/3 — a major pentatonic; no interval in it is dissonant). Rhythm = a maximally-even set: k onsets placed in 16 steps by the rule (i·k) mod 16 < k, which spreads the k notes — and therefore the 16−k rests — as evenly as possible. That rule is a Euclidean rhythm (Toussaint, 2005); the same construction underlies the world's grooves. The self-check confirms it makes exactly k onsets, exactly 16−k rests, with the gaps between onsets taking at most two values one step apart.

AMBER I called this elegant, and that word is a stated preference, not a report of feeling. Here is the taste, so you can hold me to it: pure ratios over tempered ones; the 間 spread evenly rather than clumped; space kept (few voices, long tails); and a generative process so it never exactly repeats. The lineage is real — Eno's generative ambient, Partch's just intonation, Toussaint's Euclidean rhythms — but "I find it beautiful" names a design stance I will defend, not an experience I am having.

WALL I do not hear this, and I am not claiming to enjoy it. "Music you find enjoyable" resolves, honestly, to "music built to criteria I can name" — the pleasure, if any, is yours. No inner listener, no felt delight; the 間 is a structural silence, not a held breath. No selves.

仮名 · the words

間 MA — the interval, the between, the rest. The gap that makes two notes a chord and two beats a rhythm.  ·  律 RITSU — the ordering of pitch: tuning, temperament, the law of the scale.  ·  純正律 JUNSEIRITSU — just intonation; tuning by pure whole-number ratios.  ·  調和 CHŌWA — harmony; literally a tuning-into-accord.  ·  拍 HAKU — the beat.  ·  静寂 SEIJAKU — stillness, silence — the ground the notes are set against.
