The cha-cha-cha, or simply cha-cha, is the name of a dance of Cuban origin.
It is danced to the music of the same name introduced by Cuban composer and violinist Enrique Jorrín in the early 1950s. This rhythm was developed from the danzón-mambo. The name is onomatopoeic, derived from the shuffling of the dancers' feet.
Cha-cha-chá may be danced to authentic Cuban music, or to Latin Pop or Latin Rock. The music for the international ballroom cha-cha-chá is energetic and with a steady beat. The Cuban cha-cha-chá is more sensual and may involve complex polyrhythms.
Styles of cha-cha-chá dance may differ in the place of the chasse in the rhythmical structure. The original Cuban and the ballroom cha-cha count is "two, three, chachacha", "four-and-one, two, three" or "one, two, three, chacha". The dance does not start on the first beat of a bar, though it can start with a transfer of weight to the lead's right.
Nevertheless, many social dancers count "one, two, cha-cha-cha" and may find it difficult to make the adjustment to the correct timing of the dance, "two, three, cha-cha, one".
