How does the cha-cha fit five steps into four beats of music?

The cha-cha is a ballroom dance of Latin American origin that utilizes a specific rhythmic structure to fit five steps into four beats of music.

The dance achieves this by incorporating a "triple step" or shuffle within the basic pattern. While the music is counted in four beats, the dancers perform two slow steps on the first two beats, followed by three quick steps—the "cha-cha-cha"—that occupy the remaining two beats. This syncopated rhythm is what gives the dance its characteristic energy and flair.1
