Controls
Practice
The melody lights up key by key. You follow at your own pace.
Challenge
Listen, then play it back from memory. One note longer each round.
Key mapping
The white row sits on A S D F G H J K, the black keys on W E · T Z U. If you know a real keyboard you will find middle C immediately — it is on A.
About the sound
Browsers only allow audio after your first interaction. If it stays quiet, tap a key once — everything plays after that.
What the sound is made of
No samples, no audio files. Every note is built the moment you strike it, from several sine partials with their own envelope. That is why the page loads in milliseconds and still does not sound like a beeper.
