Quick Summary

In music, duple time refers to a meter with two beats per measure. This means that each musical measure is organized around a pattern of two main beats. Common examples of duple time include 2/4 time, where there are two quarter notes per measure, and 2/2 time (also known as cut time or alla breve). In 2/4 time, the quarter note receives one beat, and there are two such beats in a measure. Cut time, indicated by a 'C' with a line through it, is a form of duple time where the half note receives one beat, and there are two beats per measure.123
