A beat is a regularly recurring pulse of emphasis in time, the temporal unit that organizes rhythmic experience in music, poetry, and movement. It is the measured interval between successive accents that structures temporal perception into patterned units — the metronomic backbone of musical meter and the stress alternations that govern prosodic rhythm in verse. A beat does not require sound: it operates as an abstract temporal scaffold that can be realized through sound, gesture, speech, or even imagined internally, but its persistence mechanism is the human capacity to track regular intervals and to coordinate action to them. The beat is the map of temporal regularity that humans impose on flowing time, enabling synchronization across bodies and between body and artifact.[formal: pulsus | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A beat is the periodic amplitude variation produced when two waves of slightly different frequencies superpose. As a concept, it is a human-made measurement technique: musicians tune by listening for beats, physicists measure unknown frequencies by comparing them to known ones, and the beat frequency directly reveals the difference between two sources. The map — naming, quantifying, and exploiting this interference pattern — is the construct.

Beats serve rhythmic organization — the regular pulse that beats provide is built to structure rhythmic patterns in music, poetry, and movement. Law 8d: servant (beat) points at master (rhythm). The designed purpose of beats is to further rhythmic experience.

Meter as a concept requires beat to operate — meter is the system of organizing beats into patterns, and without the concept of a regular pulse (beat), meter cannot function. Law 8: remove beat and meter ceases to operate. The removal test passes: meter has no operational meaning without beat.

Law 8b removal test on the pinned senses per both accepted definitions: tempo is carved as 'the measured speed or rate at which a musical composition or passage is performed, conventionally quantified in beats per minute,' its parameter (1) being 'the speed of the underlying pulse or beat.' beat is carved as 'a regularly recurring pulse of emphasis in time, the temporal unit that organizes rhythmic experience.' Remove beat now: tempo stops OPERATING — BPM has no pulse to count, the metronome mark (quarter note = N) loses the beat unit it designates, and the Italian tempo names, which name speed regions of the pulse, lose their referent. Not a naming loss (the Law 8b objection): the measured quantity itself disappears. Reverse test: beat operates fully without tempo — unmarked pulses, free rhythm, and rubato performance all operate without any fixed speed. Board precedent: meter DEPENDS_ON beat is ACCEPTED — a framework depending on the unit it measures; tempo is the RATE of that same unit, so this is the same accepted pattern, not a leap. The accepted tempo DEPENDS_ON rhythm is complementary, not subsuming: rhythm organizes events into pattern; tempo fixes the speed of the beat itself; no nearer rung (pulse, beat-unit) exists on the board. Pinned sense: tempo as the rate of beats; beat as the temporal unit whose rate tempo fixes.
- measure← CONTAINS
Pinned sense: bar as measure unit delimited by bar lines on staff. The definition states a bar contains exactly the number of beats specified by time signature. Removing beats stops bar operating as a measure unit; beats are literal temporal parts contained within the bar's span. Law 10 whole-and-part.
