Tempo
Allegro
Ready - 4/4
Example shown at 120 BPM - Space starts or stops - T taps the tempo
Ready at 120 BPM in 4/4. Press Start when you are ready to practise.
How it works
- Set a tempo from 30 to 240 BPM, or tap along with a song to measure its tempo.
- Choose a time signature - a quarter-note meter or a compound meter such as 6/8, 7/8, 9/8, or 12/8 - then decide whether beat one should be accented.
- Turn on a subdivision (eighth notes, triplets, or sixteenth notes) to hear quieter clicks inside each beat, useful for catching rushed or uneven inner rhythms.
- Press Start. The visual pulse marks every main beat while a higher click identifies the start of each measure.
From BPM to a steady pulse
BPM states how many beats occur in one minute. The delay between clicks is therefore 60 divided by the BPM. At the sample tempo of 120 BPM, each beat is 0.5 seconds apart. In 6/8, each of the six eighth notes receives a click. Turning on a subdivision splits that same beat interval further - a triplet subdivision, for example, adds two extra clicks evenly spaced inside each beat.
seconds per beat = 60 / BPM seconds per subdivision click = (60 / BPM) / subdivisions per beat tap tempo BPM = 60,000 / average milliseconds between taps
For steadier playback, the tool plans each click a fraction of a second ahead on the browser's audio clock. The timer only asks which notes need scheduling; it does not decide the exact instant each note sounds.
FAQ
How does tap tempo calculate the BPM?
Tap at least twice in time with the music. The metronome averages the intervals between your last eight taps and converts that average from milliseconds into beats per minute. Pause for two seconds to begin a fresh reading.
How accurate is this browser metronome?
It schedules clicks slightly ahead on the Web Audio clock instead of relying on a timer for each sound. That keeps the pulse stable during normal use, although Bluetooth devices and some operating-system audio settings can add audible output latency.
Will it keep playing in a background tab?
Usually yes, as long as the tab remains open and the device stays awake. A browser or operating system may still suspend audio when it enters a power-saving state, so keep the device awake for an uninterrupted practice session.
What tempos and time signatures can I use?
Choose any whole-number tempo from 30 to 240 BPM, quarter-note meters from 2/4 through 12/4, or compound meters 6/8, 7/8, 9/8, and 12/8. You can also turn the first-beat accent off for an even click.
What does the subdivision control do?
It adds evenly spaced, quieter clicks inside every beat without changing the tempo or which beat is accented. Eighth notes add one extra click per beat, triplets add two, and sixteenth notes add three - useful for hearing exactly where the middle of a beat falls when a rhythm feels rushed or uneven.
Does the metronome record or upload my audio?
No. It never accesses your microphone. The clicks are synthesized locally with the browser Web Audio API, and your tempo settings stay on your device.
