Online Metronome

Keep time at any tempo, with an accented first beat.

BPM · Allegro

Bar and sound

Runs entirely in your browser. Nothing is uploaded, and the timing stays accurate because each click is scheduled against the audio clock rather than a page timer.

How to use an online metronome

  1. Set the tempo

    Type a beats per minute value, drag the slider, or tap the tempo button in time with the music.

  2. Choose the bar length

    Pick a time signature so the first beat of each bar is accented and easy to follow.

  3. Press start

    The click begins immediately and the dots show which beat of the bar you are on.

  4. Adjust while it runs

    Tempo, time signature, and sound all change on the fly without stopping.

Why use this tool

Stays in time

Each click is scheduled against the audio clock rather than a page timer, so the beat does not drift or stutter the way a simple timer would.

Tap tempo

Tap along to a recording and the tempo is worked out from the average gap between your taps, so you can practise at the speed of the track.

Accented downbeat

The first beat of each bar sounds higher and brighter, which is what lets you hear where the bar starts instead of counting.

Four time signatures

Two, three, four, and six beats to the bar cover the vast majority of practice material.

Nothing leaves your browser

The click is generated locally with no downloads and no account, so it works the same on any device.

About this tool

A metronome marks a steady beat so you can practise in time. It is the least glamorous and most effective practice tool there is: playing along to one exposes the places where you rush and the places where you drag, which is exactly the information you need to fix them. Set a tempo, pick how many beats are in a bar, and press start.

Tempo runs from 30 to 300 beats per minute, with the traditional Italian tempo names shown alongside the number so a marking on a score translates directly. Tap tempo is the quickest way in when you are working from a recording: tap along four or five times and the speed is taken from the average gap between taps. The first beat of each bar is accented by default, which is what tells you where the bar begins without having to count, and the dots across the display track the beat visually so it still works with the sound turned down.

The timing is the part that matters. Clicks are queued a fraction of a second in advance against the audio clock rather than fired by a page timer, so the beat holds steady even when the browser is busy or the tab loses focus, which is where simpler metronomes fall apart. Everything can be changed while it runs. To measure the tempo of a track rather than set one, use the BPM counter. For a steady reference pitch instead of a beat, the tone generator plays one, and the countdown timer covers timed practice sessions.

Frequently asked questions

Why does the click only start when I press the button?
Browsers block audio until you interact with the page. That is a deliberate protection against pages that make noise on load, and it applies to every site.
Does it drift or stutter?
No. Clicks are scheduled ahead of time against the audio clock rather than triggered by a page timer, which is what keeps the beat steady even when the browser is busy.
How does tap tempo work?
Tap the button in time with the music. After two taps it shows a tempo, and it keeps averaging the last few taps so it settles quickly. Pausing for more than two seconds starts a fresh measurement.
Can I change the tempo without stopping?
Yes. Tempo, time signature, sound, and the accent all apply from the very next beat, so you can speed up gradually while you practise.
Does it work on a phone?
Yes. Press start once and the click runs the same as on a desktop. Keep the screen awake if you need it to run through a long practice session.
