preferred "measured rhythm". However, Justin London has written a book about musical metre, which "involves our initial perception as well as subsequent anticipation of a series of beats that we abstract from the rhythm surface of the music as it unfolds in time". This "perception" and "abstraction" of rhythmic bar is the foundation of human instinctive musical participation, as when we divide a series of identical clock-ticks into "tick–tock–tick–tock". "Rhythms of recurrence" arise from the interaction of two levels of motion, the faster providing the pulse and the slower organizing the beats into repetitive groups. In his book ''The Rhythms of Tonal Music'', Joel Lester notes that, "
ce a metric hierarchy has been established, we, as listeners, will maintain that organization as long as minimal evidence is present".

This recurring pattern of durations is identified at the beginning of a composition by a meter signature (time signature). ... Although meter is generally indicated by time signatures, it is important to realize that meter is not simply a matter of notation". A definition of musical metre requires the possibility of identifying a repeating pattern of accented pulses – a "pulse-group" – which corresponds to the

Frequently metres can be subdivided into a pattern of duples and triples. For example, a metre consists of three units of a pulse group, and a metre consists of two units of a pulse group.

Metres classified by the subdivisions of a beat
Simple metre and compound metre are distinguished by the way the beats are subdivided.
Simple metre
Simple metre (or simple time) is a metre in which each beat of the bar divides naturally into two (as opposed to three) equal parts. The top number in the time signature will be 2, 3, 4, 5, etc.
For example, in the time signature , each bar contains three quarter-note beats, and each of those beats divides into two

contains a triple pulse. The top number in the time signature will be 6, 9, 12, 15, 18, 24, etc.
Compound metres are written with a time signature that shows the number of ''divisions'' of beats in each bar as opposed to the number of beats. For example, compound duple (two beats, each divided into three) is written as a time signature with a numerator of six, for example, . Contrast this with the time signature , which also assigns six eighth notes to each measure, but by convention connotes a simple triple time: 3 quarter-note beats.
Examples of compound metre include (compound duple metre), (compound triple metre), and (compound quadruple metre).

If the beat is divided into two the metre is ''simple'', if divided into three it is ''compound''. If each bar is divided into two it is ''duple'' and if into three it is ''triple''. Some people also label quadruple, while some consider it as two duples. Any other division is considered additively, as a bar of five beats may be broken into duple+triple (12123) or triple+duple (12312) depending on accent.

Hypermetre

Hypermetre is large-scale metre (as opposed to smaller-scale metre).
Hypermeasures consist of
hyperbeat
In music and music theory, the beat is the basic unit of time, the pulse (regularly repeating event), of the ''mensural level'' (or ''beat level''). The beat is often defined as the rhythm listeners would tap their toes to when listening to a pi ...

The term was coined, together with "hypermeasures", by
Edward T. , who regarded it as applying to a relatively small scale, conceiving of a still larger kind of gestural "rhythm" imparting a sense of "an extended upbeat followed by its downbeat" contends that in terms of multiple and simultaneous levels of metrical "entrainment" (evenly spaced temporal events "that we internalize and come to expect", p. 9), there is no in-principle distinction between metre and hypermetre; instead, they are the same phenomenon occurring at different levels.

With polymetre, the bar sizes differ, but the beat remains constant. Since the beat is the same, the various metres eventually agree. (Four bars of = seven bars of ). An example is the second moment, titled "Scherzo polimetrico", of

, the number of beats varies within a fixed bar length. For example, in a 4:3 polyrhythm, one part plays while the other plays , but the beats are stretched so that three beats of are played in the same time as four beats of . More generally, sometimes rhythms are combined in a way that is neither tactus nor bar preserving—the beat differs and the bar size also differs. See
Polytempi.
