The online metronome keeps precise time so you can practice any instrument without relying on a separate app. Adjust the tempo between 30 and 300 beats per minute (BPM) with the slider or the buttons, choose the time signature (from 2/4 to 8/4) so the first beat of each bar sounds accented, and follow the visual beat indicator as you play. If you don't know the tempo of a song, use the tap tempo button: tap along a few times and the metronome calculates the exact BPM. Everything runs with the Web Audio API directly in your browser, with minimal latency and no file involved.

Frequently asked questions
Does it work offline once loaded?
The sound is generated by the Web Audio API in your own browser, it doesn't depend on any server to work.
What is tap tempo?
It's a way to calculate BPM by tapping along to a rhythm you hear: the metronome measures the time between your taps and calculates the exact tempo.
Why does the first beat sound different?
It's accented (higher pitch) so you always know where each bar starts, just like on a physical metronome.
What BPM range does it support?
From 30 to 300 BPM, covering everything from very slow tempos (Largo) to very fast ones (Presto).
