Cha Cha (sometimes wrongly called Cha Cha Cha based on a "street version" of the dance with shifted timing) was delevoped by Enrique Jorrín in the early 1950s, as a slower alternative to Mambo—and, in fact, was originally called Triple Mambo. The Cha Cha is a flirtatious dance with many hip rotations and partners synchronising their movements. The dance includes bending and straightening of the knee giving it a touch of Cuban motion. Cha-cha is performed for both International Latin and American Rhythm.
