Free Online Metronome

Most browser metronomes lie to you. They click, you play along, and nothing tells you whether you were actually in time — so you practise for a year and get better at nothing in particular. This one measures.

Why most browser metronomes can't tell you the truth

Every browser puts latency between the moment a sound is scheduled and the moment it leaves your speakers, and that number is different on every machine. A metronome that ignores it will happily tell a dead-on player that they are dragging by 40 ms.

So this one leads with consistency, not tendency. Consistency is the one reading a constant latency offset mathematically cannot distort — if every note you play is 40 ms late, your spread is still tight, and tight is what actually matters. Then, rather than asking you to guess at your own latency, hit Calibrate ms: it plays ten clicks out of your speakers, times their return through your mic, and measures the offset instead of assuming it.

Aim for a spread under 10 ms at 120 BPM before you raise the tempo. Speed on top of a loose pocket just builds a faster loose pocket.

Three drills worth your time

2 & 4 — the backbeat. Set 120 BPM, put the click on beats 2 and 4 only, and comp a Charleston (1 & a 2 &). This is the single fastest way to stop hearing the click as a metronome and start hearing it as a drummer's hi-hat.

Drop the click. 160 BPM, mute one bar in every four, and play guide-tone lines through a ii–V–I in B♭ — D–F over Cm7, F–B over F7, E–B over B♭maj7. The muted bar is the test. If you come back in on the wrong beat, that is your real time feel, not the one you have with a click babysitting you.

Trade fours. Four bars of click, four bars of silence. Solo through the silence, comp through the click. Then check your spread on each segment separately — most players are far steadier when the click is on, and the gap between those two numbers is the thing to close.

Tempos by feel — where the grooves actually live

Nobody counts beats per minute on a bandstand; they call a feel. This is roughly where the feels live, so when a chart says medium swing you know what to dial in.

Common questions

What BPM should I practice scales at?

Start wherever it's clean, not wherever you wish you were. Groove at that tempo until it's relaxed, then bump 3–5 BPM. Quality compounds; tension compounds faster.

How do I practice with a metronome on 2 and 4?

Halve the BPM and hear the clicks as beats 2 and 4 — the drummer's hi-hat. You supply beat 1 yourself, which is exactly the skill. The 2 & 4 preset above does this for you.

Why is playing with a metronome so hard?

Because it tells the truth. It exposes exactly where you rush and drag. Strip the notes down — clap or mute-strum the groove first — then add the lines back.

How do I use a metronome to get faster?

Alternate days: slow with bigger subdivisions, then faster with fewer clicks. Speed you gained while tense isn't speed, it's a ceiling you'll pay for later.

Should I always practice with a metronome?

No. Alternate time-on and time-off — sing, play over the drone, play rubato. You're building both the grid and the feel, and they're different muscles.
