Rhythm, Meter, and Tempo
How music organizes duration into patterns of beats, accents, and speed.
Definition
The organization of musical duration — the patterning of sounds and silences (rhythm) within a periodic framework of accented and unaccented beats (meter), unfolding at a given speed (tempo).
Scope
Covers the notation and theory of musical time: note and rest values, the grouping of beats into simple and compound meters, time signatures, syncopation and hemiola, and the indication of tempo. Treats meter as a cognitive framework of expectation as well as a notational convention; excludes pitch organization, handled separately.
Core questions
- How are durations notated and subdivided?
- What distinguishes simple from compound meter, and duple from triple?
- How does a listener infer meter from a rhythmic surface?
- What are syncopation and hemiola, and how do they play against an established meter?
- How is tempo specified and why does it matter to musical character?
Key theories
- Metric hierarchy and rhythmic grouping
- Cooper and Meyer analyzed rhythm as nested levels of grouped strong and weak pulses, an architectonic hierarchy later refined by cognitive accounts (e.g. London) that treat meter as an internalized pattern of attentional expectation rather than mere notation.
History
Mensural notation of the late Middle Ages first fixed proportional durations; the bar line and regular meter became standard in the seventeenth century, and twentieth-century cognitive research reframed meter as a perceptual phenomenon.

Frequently asked questions
- What is the difference between rhythm and meter?
- Rhythm is the actual pattern of durations you hear; meter is the underlying grid of regularly recurring strong and weak beats against which that rhythm is measured.
- Is meter purely a notational convention?
- It is notated with time signatures and bar lines, but cognitive research treats meter as a listener's internalized expectation of where accents fall, which is why syncopation is felt as a tension.
