Where salsa comes from
7.Cousin #4: cha-cha-chá
Cha-cha-chá slowed mambo down so social dancers could follow it more easily. It was created in Havana in the early 1950s, and its name copies the sound of the dancers' three quick steps.
Salsa borrowed rhythm, instruments, and dance moves from all four of these cousins: danzón, rumba, mambo, and cha-cha-chá.
