A style of music and dance of Cuban origin that became popular in the 1950s. It was derived from the Mambo and was originally called the cha-cha-cha. The dance consists of five steps in the four beats of each measure with two slow steps and three quick steps. The name came from the rhythm of the music that sets up the triple step (or three quick steps), but was eventually shortened to cha-cha. This dance is still very popular today and is included as one of the five dances in international ballroom dance competition.
