A steady drone holds; slide your note against it and listen for the beating to slow and stop at the pure interval.

How to play
Each round names an interval to tune above a held drone. Drag the slider or the canvas to move your note; the screen shows the acoustic beating as a pulsing meter and a beats-per-second readout. When the beating stops, you are sitting on the pure, just-intonation pitch, lock it in. Six intervals make a challenge.
Tune your note so the beating against the drone slows to nothing
The meter pulses when detuned and steadies when pure; cents-off is shown too
Lock in each interval; closer to pure scores higher
