About this tool
A drone is a single sustained pitch you can play against — and this generator holds any note rock-steady for as long as you need, using the Web Audio engine in your browser. Pick a note or type an exact frequency, press play, and tune your instrument to it, practise your intonation, play along over a tanpura-style backdrop, or simply relax to a held tone. Start the sound with a tap or click, since browsers require a gesture before any audio can play, and keep your volume at a comfortable level.
Frequently asked questions
What can I use a drone for?
Holding a steady reference pitch is one of the best ways to train intonation: play or sing against the drone and you immediately hear when a note drifts sharp or flat. Indian classical musicians practise over a tanpura drone for exactly this reason. A drone is also handy for tuning, for finding a key by ear, or simply as a calm, continuous tone for focus and meditation.
Why is there no sound when I open the page?
Web browsers block audio until you interact with the page, so the drone stays silent until you press play — a deliberate rule that stops sites blaring at you unannounced. Tap or click start, then raise your device volume gradually. Because a drone is a continuous, full-level tone, it is best to begin quietly and turn it up to a comfortable level rather than starting loud.
Can I set an exact frequency like 432 Hz?
Yes. As well as choosing a note name, you can dial in a precise frequency in hertz, so you can drone on A at 432 Hz, match an instrument tuned away from the standard 440, or sound any pitch you need for an experiment. The tone is generated live by the Web Audio API, so it holds perfectly steady for as long as you like without any audio file.
