Cut Time Definition in Musical Terms

Definition

Cut time (or “cut common time”) is a 4/4 time signature that’s been rhythmically “cut” to manipulate rhythm and/or tempo. Cut time can be written as 2/2, or as a c-shaped symbol with a vertical slash (see image).

Cut time is used for the following rhythmic effects:

To Mimic a March: The rhythm of 2/2 time is similar to that of 2/4 - also known as “march” time - because both have the downbeat on every other beat.
To Speed Up the Tempo: When switching from common time, cut time means you’ll be playing twice as fast. In this manner, cut time can be referred to as “half time,” or “playing in 2.”
