Tool · The Master Clock
BPM Tap
Tap the space bar or the circle below on the beat. After four taps the meter locks onto your tempo. Use this to find the BPM of anything playing — a track, your own heartbeat, the room.

Beats per minute
Why this matters. The framework's master clock is not an abstraction. In house music, the kick drum lands at roughly 118–128 BPM — close to twice the resting human pulse, which is the entrainment frequency the body is built for. When you tap along with a track, you are literally testing whether your body has found its coupling to that track's master oscillator.
Readout. The number is the rolling average of your last four inter-tap intervals. After the first four taps it locks; the ring around the tap target pulses at your measured tempo. Use the ÷2 and ×2 buttons if you were tapping at half or double the intended rate.
Keyboard. Press Space to tap. R resets. The tool is fully keyboard-operable.
