Three Worlds, Three Sets of Rules: Ocean, Forest, Space
Short answer: All three worlds run on the same engine: the same shapes, the same drifting, the same rule that sound starts when shapes touch. What changes is the material. Each world has its own notes, its own instruments and its own kind of room. Ocean is free. Forest and Space open together with a one-time payment.
| Ocean | Forest | Space | |
|---|---|---|---|
| Feels like | Deep, slow, underwater | Warm, still, ceremonial | Weightless, open |
| Made of | Whale calls, sonar pings, slow tides | Temple bells, singing bowls, soft chants | Radio static, whistles, short runs of beeps, a low drone |
| Notes | Low and widely spaced | Higher, built on open fifths | Only the notes of one wide, open chord |
| The room | Large and submerged | A very long tail and a dark echo | Almost no room, and one long echo |
| Pulse | A slow heartbeat | A quiet bowl strike | None |
| Access | Free | One-time payment | One-time payment |
What stays the same
The five shapes keep their jobs in every world: circles are textures, squares are harmony, triangles are creatures, bars are drones, diamonds are percussion. The way they move is identical. So is the way they trigger sound. If you know one world, you can read the other two.
I first thought of the worlds as three separate instruments. They are closer to one instrument with three sets of strings.
What changes, and why it is enough
The notes. Ocean uses low notes spaced far apart, so they never crowd each other. Forest sits higher and leans on fifths, which is what makes it sound like bells and bowls. Space uses only the notes of one wide, open chord, so any two sounds that meet belong together. It started on a scale with no home note, which I wrote about in Whole Tones Have No Home.
The instruments. Every shape gets a different sound in each world. A triangle is a whale in Ocean, a singing bowl in Forest and a radio whistle in Space.
The room. Ocean sounds like a big space full of water. Forest has a tail so long that one bell is still ringing when the next begins. Space has almost no room at all, because space has no walls. What it has is a single long echo: a sound leaves, and a while later it answers from far away.
Where Space breaks the rules
Space is the one world where I changed the engine a little. It has no pulse. It allows fewer sounds at once. And it enforces a gap of quiet between its bigger events. Without those three changes it filled up and stopped feeling empty, which is the one thing space should feel.
Getting Space to sound unlike Forest took the longest. That story is in Why a Fifth Plus a Soft Onset Is Always a Singing Bowl.
