Drone Anchor

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

Controls

• Desktop: drag the tuning slider or drag across the canvas, toggle sound, hear the pure target, then Lock it in
• Phone & tablet: drag the slider or swipe the canvas to tune

Game modes

• Daily: a shared set of six intervals seeded from today's date
• Practice: fresh challenges on demand

Tips & strategy

• Turn sound on and tune by ear — the slowing beats are a clearer guide than the numbers
• Use Hear pure target to memorize the goal, then steer your note onto it
