Is this metronome accurate?

The clicks are timed by your browser's audio clock — the same clock audio apps use — not by a page timer, so they don't drift with the page. Bluetooth audio adds a fixed delay you'll hear as the click arriving late.

Does it keep going in the background?

Yes. When the tab is hidden it schedules clicks further ahead, so it keeps time even though browsers slow background timers. On phones, locking the screen may still stop it.

Can I open it at a set tempo?

Yes: add ?bpm=120 to the address — Tap BPM links here with the tempo you tapped.

Is anything recorded?

No. It only plays sound; nothing is recorded or sent.

How to use this

What it does

Plays a click at the tempo you set, with the first beat of each bar accented and optional eighth, triplet or sixteenth subdivisions. Clicks are scheduled on the browser's audio clock a fraction of a second ahead, so the timing doesn't drift when the page is busy — and further ahead when the tab is in the background.

What you'll need

A tempo in BPM (20–300)
A time signature and how many clicks per beat

Steps

Set the tempo with the number, the buttons, the slider or the arrow keys.
Pick a time signature, subdivisions and a sound.
Press Start (or Space).

Reading the result

The dots show where you are in the bar; the big one is beat one. Changing the tempo while it plays takes effect on the next click.

Tips

Practise a hard passage 10–20 BPM under tempo and move up in small steps.
Use subdivisions to lock in the eighths or sixteenths, not just the beat.
Find a song's tempo first with Tap BPM, then open it here.

What is a metronome?

A metronome clicks at a steady tempo, measured in beats per minute (BPM). Musicians use it to practise in time, to record to a fixed tempo, and to learn what a tempo marking feels like.

The time signature sets how many beats are in a bar; the accent marks the first one. Subdivisions add quieter clicks between the beats.

Why musicians use it

Steady time is what makes a band sound tight and a recording easy to edit. Practising with a click shows where you rush or drag.

Common mistakes

Practising only at full speed. slow, clean repetitions build accuracy faster than fast, messy ones.
Hearing only the beat. subdivisions reveal uneven eighths and sixteenths.
Bluetooth headphones. they add delay; for playing along, wired headphones or speakers are tighter.
