ChaChaChá

Chachachá, or simply cha-cha in the United States, is a dance of Cuban origin. It is danced with the music of the same name presented by the Cuban composer and violinist Enrique Jorrin in the early 1950s. This rhythm was developed from the danzón-mambo. The name of the dance is an onomatopoeia derived from the dragging sound of the dancers' feet.
The basic pattern of the footwork of the chachacha (two, three, chachacha) is also found in several Afro-Cuban dances of the Santería religion. For example, one of the steps used in the dance for the orisha Oggun uses an identical footwork pattern. These Afro-Cuban dances are prior to the development of chachacha and were known to many Cubans in the 1950s, especially those of African origin. Therefore, some have speculated that the chachacha footwork was inspired by these Afro-Cuban dances.
