About the Online Metronome

A reliable metronome is essential for every musician's practice routine. Unlike most online metronomes that rely on imprecise JavaScript timers (setTimeout/setInterval), our metronome uses the Web Audio API's hardware audio clock — the same timing source professional audio software uses. This means sub-millisecond accuracy that doesn't drift, even when the browser tab is backgrounded.

The interface shows a visual beat indicator with amber accent on beat 1 (the downbeat) and blue for beats 2-4. The large BPM display is easy to read across the room, and the tempo slider offers fine control with +/-1 and +/-5 buttons for quick adjustments.

FAQ

Frequently Asked Questions

Is this online metronome accurate?
Yes. Unlike standard JavaScript timers, our metronome schedules clicks directly on the hardware Web Audio API audio clock (AudioContext.currentTime), delivering sub-millisecond precision regardless of browser tab throttling.
What is the standard tempo for practice?
Beginner practice usually starts at 60–80 BPM. Moderato is around 108–120 BPM. Allegro starts above 120 BPM. The average pop song is 100–130 BPM.
How do I set the time signature?
The default is 4/4. The first beat of each measure is accented (higher pitch) to help you track where you are in the bar.
Can I use this metronome offline?
Yes, once loaded the metronome continues to run offline since all timing is handled by the Web Audio API locally.
What tempo range is supported?
The metronome supports 30 to 300 BPM, covering the full range from Larghissimo to Prestissimo.
Is there a visual beat indicator?
Yes, each beat lights up a visual indicator. The first beat of each measure is highlighted in amber for clear downbeat recognition.
How do I find the BPM of a song?
Use our BPM Tapper tool. Tap along to the beat and it calculates the tempo using statistical averaging.
Can I adjust the volume?
The metronome has a fixed output level. Use your device's volume control or our BPM Tapper for a quieter reference.
Does it work on mobile?
Yes, the metronome is fully responsive and works on all devices with touch controls.
Why does the metronome keep playing after I close the tab?
It shouldn't. The metronome stops when you click Stop or navigate away. If this happens, please report it as a bug.
