Time signature

Specification of beats in a musical bar/measure

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 44 (spoken as four–four time), or a time symbol, such as or (spoken as common time or cut time, respectively).
