Martin went down a rabbit hole on Saturday — Max/MSP led to SuperCollider led to Radiohead — and somewhere in that spiral is an idea Brian Eno had already worked out in 1978.
The Tape Loop Idea
Eno’s insight was this: you don’t have to write every note. You write the system.
Ambient 1: Music for Airports was made by recording single piano notes onto tape loops of different lengths — 17½ seconds, 22¾ seconds, others. The loops run simultaneously. Because their lengths are incommensurable, they phase in and out of alignment and the patterns that emerge are never quite the same twice. Eno called this generative music: you design the rules, set them in motion, and listen. The constraint isn’t a limitation on the composition. The constraint is the composition.
He wrote in the liner notes: “Ambient music must be able to accommodate many levels of listening attention without enforcing one in particular.” That’s a design brief.
Oblique Strategies, made with Peter Schmidt in 1975, applies the same logic to the studio. It’s a physical deck of cards — each one printed with a single cryptic instruction, kept in a black box in the studio — that gives you constraints on demand — “Honour thy error as a hidden intention.” “Work at a different speed.” “Only one element of each kind.” You pull one when you’re stuck. It narrows the space. The card closes off most of the options and makes the rest navigable. Unlimited options are paralyzing. Fewer options — the right kind of fewer — are generative.
The Same Complaint
Jonny Greenwood got to the same place through a different door.
Nigel Godrich heard about Max/MSP at a dinner party from a Stanford graduate and brought it to Radiohead during Hail to the Thief. Here’s what Greenwood said about why it mattered:
“I’ve always felt uncomfortable having to use other people’s software to make music. However limitless sequencers, audio editors, and plugins claim to be, you still find yourself being forced, however subtly, to work in certain ways… With Max/MSP I finally got to think about sound and MIDI, and their manipulation, in a much purer way.”
This is Eno’s complaint restated. Standard software has opinions. It wants music in four-bar units, in recognizable time signatures, through workflows that already have names. Greenwood wanted to get underneath that — to work with sound before it had been organized into categories.
For In Rainbows, Max was likely used to generate the beat patterns on “15 Step” — those odd, lurching subdivisions that give the track its unsettled quality. For Kid A, “Idioteque” started as a 50-minute improvisation with a modular synthesizer, with Greenwood intentionally introducing chaos. Thom Yorke listened through the whole thing, found about 40 seconds of it that he called “absolute genius,” cut it up, and that became the track. “Treefingers” from the same record — guitar loops processed through effects until unrecognizable as guitar — Greenwood described simply as: “It’s quite Eno-ish, isn’t it.”
He meant it as a compliment. He knew exactly what he was saying.
Add Constraints to Your Systems
What Eno understood, and what Greenwood rediscovered, is that a tool with no predefined structure isn’t the same as a tool with no constraints. Max/MSP is not freedom from constraints — it’s a blank canvas on which you build your own constraints. The system you write is the composition. What comes out surprises you precisely because you couldn’t have written it directly.
SuperCollider takes this further: code only, no visual interface, the rules written out as text. The musical equivalent of removing all scaffolding between yourself and the idea.
The question Martin ended up with after the rabbit hole: if you can get interesting music by designing systems and constraints, what else works that way?
