who invented the cha cha dance and in what year
Cha-cha-cha (dance) The cha-cha-chá, or simply cha-cha in the U.S., is a dance of Cuban origin.[1][2] It is danced to the music of the same name introduced by Cuban composer and violinist Enrique Jorrin in the early 1950's. This rhythm was developed from the danzón-mambo. The name of the dance is an onomatopoeia derived from the shuffling sound of the dancers' feet.[3]
