Time signature
A time signature (also known as meter signature, metre signature, and measure signature) is an indication in music notation that specifies how many note values of a particular type fit into each measure (bar). The time signature indicates the meter of a musical movement at the bar level.
In a music score the time signature appears as two stacked numerals, such as 4
4 (spoken as four–four time), or a time symbol, such as 
(spoken as common time). It immediately follows the key signature (or if there is no key signature, the clef symbol). A mid-score time signature, usually immediately following a barline, indicates a change of meter.
Most time signatures are either simple (the note values are grouped in pairs, like 2
4, 3
4, and 4
4), or compound (grouped in threes, like 6
8, 9
8, and 12
8). Less common signatures indicate complex, mixed, additive, and irrational meters.
Most time signatures consist of two numerals, one stacked above the other:
For instance, 2
4 means two quarter-notes (crotchets) per bar, while 4
8 means four eighth-notes (quavers) per bar. The most common time signatures are 2
4, 3
4, and 4
4.
By convention, two special symbols are sometimes used for 4
4 and 2
2:
These symbols derive from mensural time signatures, described below.
Simple meters are those whose upper number is 2, 3, or 4, sometimes described as duple meter, triple meter, and quadruple meter respectively.
