Musically, the Cha-cha-cha was perhaps not a great innovation. However, it became hugely popular because people found it easy to dance to. Monsieur Pierre and his colleagues went to Cuba in the early 1950s to study it. They came back to London and codified the dance (sorted it out and wrote it down). It became a standard dance in Latin American ballroom dancing. It is one of the five Latin dances in international competitions governed by the World Dance Council. Today it is still popular as a dance, and is still danced in Cuba.
