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 1953. This rhythm was developed from the danzón by a syncopation of the fourth beat. The name is onomatopoeic, derived from the rhythm of the güiro (scraper) and the shuffling of the dancers' feet. The ballroom style of dancing the cha-cha comes from studies made by dance teacher Monsieur Pierre (Pierre Zurcher-Margolle), who partnered Doris Lavelle. Pierre, then from London, visited Cuba in 1952 to find out how and what Cubans were dancing at the time. He noted that this new dance had a split fourth beat, and to dance it one started on the second beat, not the first. He brought this dance idea to England and eventually created what is now known as ballroom cha-cha. Cha-cha may be danced to authentic Cuban music, or to Latin Pop or Latin Rock. The music for the international ballroom cha-cha is energetic and with a steady beat. The Cuban cha-chá is more sensual and may involve complex polyrhythms. 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".
