How to use the metronome

Set the tempo with the number box, the plus and minus buttons or the slider (20 to 300 BPM), then press Start. The numbered circles flash with every beat of the bar. Press Space on a keyboard to start and stop, and use the arrow keys to nudge the tempo.

Time signatures, accents and subdivisions

  • Beats per bar and the beat note give any signature from 1/4 to 12/16.
  • Click a beat circle to accent it, mute it or return it to normal.
  • Choose eighth notes, triplets or sixteenths for softer clicks between the beats.

Tap tempo

Do not know the BPM of a song? Tap along with the music on the Tap tempo button and the tool measures it for you. Four or more taps give a stable result.

Practice tips

Start slower than you think you need, get the passage clean, then raise the tempo by 4 to 5 BPM at a time. Use the soft tone or wood block for a less sharp sound, and the volume slider to blend it with your instrument.

FAQ

How accurate is the timing?

Beats are scheduled ahead on the browser audio clock, the same clock used for sound output, instead of with ordinary timers. That removes the jitter of JavaScript timers, so the tempo stays steady even when the page is busy.

How does tap tempo work?

Tap the Tap tempo button (or press T) in time with the music. The tool averages the gaps between your last eight taps and sets the BPM. If you pause for more than two and a half seconds the count starts again.

How do I set a time signature?

Pick the number of beats per bar (the top number) and the beat note (the bottom number), for example 6 and 8 for 6/8. The numbered circles show each beat of the bar; the first beat is accented by default.

Can I change which beats are accented?

Yes. Click a beat circle to cycle it between accent (strong click), normal and muted. This lets you build patterns such as accents on beats 1 and 4 in 6/8.

What are subdivisions?

Subdivisions add quieter clicks between the main beats: eighth notes (two per beat), triplets (three) or sixteenth notes (four). They help you feel the pulse when playing slowly.

Does it keep playing in a background tab?

The timer runs in a separate worker so playback normally keeps going when you switch tabs, though phones may pause audio when the screen locks.
