Metre is related to and distinguished from pulse, rhythm (grouping), and beats: Meter is the measurement of the number of pulses between more or less regularly recurring accents. Therefore, in order for meter to exist, some of the pulses in a series must be accented—marked for consciousness—relative to others.

Beats are related to and distinguished from pulse, rhythm (grouping), and meter: Meter is the measurement of the number of pulses between more or less regularly recurring accents. Therefore, in order for meter to exist, some of the pulses in a series must be accented—marked for consciousness—relative to others.
Most time signatures consist of two numerals, one stacked above the other: The lower numeral indicates the note value that the signature is counting. This number is always a power of 2 (unless the time signature is irrational), usually 2, 4 or 8, but less often 16 is also used, usually in Baroque music. 2 corresponds to the half note (minim), 4 to the quarter note (crotchet), 8 to the eighth ...
One difficulty in defining tempo is the dependence of its perception on rhythm, and, conversely, the dependence of rhythm perception on tempo. Furthermore, the tempo-rhythm interaction is context dependent, as explained by Andranik Tangian [ 29 ] [ 30 ] using an example of the leading rhythm of ″Promenade″ from Modest Mussorgsky 's Pictures ...
In a compound meter, there is an additional rhythmic grouping within each measure. This example shows 6 8 time, indicating 6 beats per measure, with an eighth note representing one beat. The rhythm within each measure is divided into two groups of three eighth notes each (notated by beaming in groups of three).
Scholes 1977b A rhythm that accents another beat and de-emphasises the downbeat as established or assumed from the melody or from a preceding rhythm is called syncopated rhythm. Normally, even the most complex of meters may be broken down into a chain of duple and triple pulses [ 32 ] [ 16 ] either by addition or division .
Before the modern concept and notation of metric modulations composers used the terms doppio piu mosso and doppio piu lento for double and half-speed, and later markings such as: (Adagio) = (Allegro) indicating double speed, which would now be marked (=). [13] The phrase l'istesso tempo was used for what may now be notated with metric ...
