That statement is incorrect. Duple meter refers to a musical meter in which each measure has two beats.
Duple meter is a musical term used to describe a rhythmic pattern in which each measure contains two beats. This means that when a piece of music is in duple meter, you can count along with it using a steady pulse that divides the music into two equal parts. The most common example of duple meter is 4/4 time, where there are four beats in each measure and each beat is divided into two equal parts.
