The calculation in one line

Tap the kick or another repeating quarter-note pulse through at least eight beats. Reset when the arrangement changes tempo.

Worked example

A stable series of taps roughly 469 ms apart corresponds to about 128 BPM.

What should I tap in a dense arrangement?

Follow the layer that best represents the main count—often the kick, a repeated bass attack or the conductor-like body pulse. Avoid changing from hi-hat subdivisions to snare backbeats during the same measurement.

Three checks before using the answer

• Measure a stable chorus or groove section.
• Use at least 8 taps before trusting decimals.
• Check half and double tempo when the answer feels implausible.

A detail that changes the interpretation

A tempo detector and a human can return 87 and 174 BPM for the same breakbeat because they selected different metric levels.

Most common mistake

Tapping every hi-hat and reporting double the intended tempo. Check whether half the result better matches the musical count.

Where the calculation stops

Manual tapping measures the pulse you choose; it does not detect tempo maps, meter changes or transient placement automatically.

Research note

Apple documents that complex material may need manual downbeats when automatic beat mapping is unreliable. Read Apple’s guide to matching project tempo to an audio region and Apple’s Logic Pro tempo overview. External documentation supports the technical context; its publishers do not endorse PulseKit.
