Metronome

An accurate Web Audio metronome with tempo, beats per bar and subdivision settings. Your settings are remembered.

This browser does not provide the Web Audio API, so the metronome cannot run.

How to use

Set the tempo (30–240 BPM) with the slider, or tap the Tap tempo button a few times in rhythm.
Choose beats per bar (2–8) and a subdivision (quarter, eighth, triplet, sixteenth).
Press Start; the first beat of each bar clicks at a higher pitch.

Notes

Clicks are scheduled ahead of time against the Web Audio clock (a 25 ms scheduler reserving 0.1 s ahead), so the tempo stays stable even when the tab is busy. Your tempo, beats and subdivision are saved in this browser's localStorage and restored on your next visit.

FAQ

What does the triplet subdivision do?: It clicks three evenly spaced notes per beat, for practicing eighth-note triplets and similar patterns.
How accurate is tap tempo?: It averages the intervals of your taps within the last 2 seconds. Four or more taps give a stable result.
