- What
- Guess the tune, six games in one
- From
- Out-of-copyright tunes, and real recordings credited on every answer
- Made
- Notes synthesized in your browser and drawn on the spiral, one at a time
Six ways to play.
Every game draws its clue on the spiral. Notes land on spokes, octaves stack on the same spoke, and a tune leaves a trail you can learn to read.
This is the soundcheck. The app is quicker, does far more, and is free on iPhone and Android in November. Premium adds your session card, 5‑minute clips and premium themes. See the app
| Today | One tune a day, the same one for everyone. | Daily |
|---|---|---|
| Tunes | The whole deck of out-of-copyright tunes, from Twinkle Twinkle to the William Tell Overture. | 36 |
| Shapes | Chords, scales and intervals, named by the shape they draw. | |
| Sounds | Everyday noises: a rooster, a doorbell, a steam whistle, a whale. Mostly real recordings. | 29 |
| Diagnostics | What doctors, mechanics and scientists listen for, from a heartbeat to a black hole merger. | 32 |
| Reverse | Hear a tune, then pick the spiral that drew it. |
Easy gives you four answers to tap, Medium gives you eight, and Hard has you type it. The game starts on Hard.
Wear the answer.
The guess the tune tee has a tune drawn on the back as a trail of dots, the way the game draws it. Wear it and see who can name it.
See it on the merch tableCredits and small print.
Every recording in Sounds and Diagnostics names its source and its license on the answer screen, the moment the round ends. The full list is under About this build, at the foot of the game.
Diagnostics is a game, not a medical device. Nothing in it diagnoses anything.
Get on the list.
The app opens in November. Leave your email and we'll tell you the day it opens.
