Tap Tempo: find a song’s BPM without guessing

Choose the beat before the button

Listen for a pulse you could comfortably walk or nod to. Keep tapping that same level of pulse. Do not switch between tapping every beat and tapping every other beat midway through the estimate.

Fast hi-hats or repeated notes may be subdivisions of the beat. If you tap twice per main beat, your reading will be about twice the intended BPM. Tap every other beat and it will be about half. Both can feel plausible; the musical grouping tells you which beat unit you need.

Take a useful first reading

1. Stop the web metronome so its existing click does not pull you toward the old tempo. Turn drums off for this exercise.
2. Listen to a stable part of the song. Press “Tap tempo” once per chosen beat, about six times, keeping the movement relaxed.
3. Read the BPM, then tap another short series to see whether the result settles near the same value. This tool averages recent intervals and displays a rounded number, so small fluctuations are normal.
4. For a fresh estimate, pause more than three seconds before your next tap. Wait for a second tap before expecting a new value: a single tap cannot define an interval.

Check the pulse, not only the number

Set 4/4 and Main beat, then press Start. Compare a few bars with the same steady passage of music. Listen for whether the click stays near your chosen pulse or drifts away; adjust the BPM slightly if needed.

Starting the click does not automatically align it with the song’s first beat. Matching tempo and matching phase are different. Stop and restart near a beat if you want a closer comparison, but do not expect automatic synchronisation or a perfect long-term lock.

If your taps settle around 160 but you intended a slower pulse, try tapping every other pulse and compare a reading near 80. These are illustrative numbers, not a claim about any particular song.

Practise the estimate without a song

1. Set the metronome to 90 BPM with Main beat. Listen for four bars, then stop it.
2. Keep that pulse in your head and make six even taps on “Tap tempo”. Compare the resulting number with 90; it is feedback about your estimate, not a pass/fail score.
3. Listen to 90 again and repeat. Notice whether you tend to speed up or slow down after the reference stops.

Know when a fixed BPM is not enough

A live performance may speed up or slow down intentionally. One fixed BPM will not follow those changes. Choose a short stable passage for your estimate, or retap when the musical tempo changes.

The web tool accepts 20–300 BPM. Its keyboard shortcut is T when focus is not inside a field, selector, button or link. If T does nothing while you are editing a setting, use the Tap tempo button instead.
