What it does
A metronome is a practice tool that plays a steady click at the tempo you set, measured in beats per minute (BPM). This one runs entirely in your browser with the Web Audio API: choose 40–208 BPM, pick 2, 3, 4, or 6 beats per bar with an accented first beat, or tap the tempo yourself. Nothing is uploaded — the clicks are synthesized on your device.
How to use
2. Press Start
The beat indicator flashes on every beat. Set the volume so the click sits comfortably under your instrument.
3. Tap tempo
Tap the Tap button in rhythm a few times and the metronome matches your tempo automatically.
Limitations
Timing precision depends on your device and browser. If the tab goes to the background, the browser may throttle timers and the beat can drift — keep the tab visible while you practice. This tool keeps time; it does not replace a teacher for technique or musicality. For tempos below 40 BPM, use a timer instead.
FAQ
Do I need an account?
No. It runs right in your browser — no install, no signup.
Why does the beat drift in a background tab?
Browsers throttle timers in background tabs to save battery. Keep this tab visible while you practice.
What do the beat counts mean?
Two, three, four, or six beats per bar, like 2/4, 3/4, 4/4, or 6/8 time. The first beat of each bar plays a higher-pitched accent click.
Is 40–208 BPM enough?
It covers Largo (40) to Prestissimo (208) — the full practical range for most instruments.
