Danzón-mambo in the context of Pérez Prado

Cha-cha-chá (Spanish pronunciation: [ˌtʃa ˌtʃa ˈtʃa]) is a genre of Cuban music. It has been a popular dance music which developed from the danzón-mambo in the early 1950s, and became widely popular throughout the world.

Mambo is a genre of Cuban dance music pioneered by the charanga Arcaño y sus Maravillas in the late 1930s and later popularized in the big band style by Pérez Prado. It originated as a syncopated form of the danzón, known as danzón-mambo, with a final, improvised section, which incorporated the guajeos typical of son cubano (also known as montunos). These guajeos became the essence of the genre when it was played by big bands, which did not perform the traditional sections of the danzón and instead leaned towards swing and jazz. By the late 1940s and early 1950s, mambo had become a "dance craze" in Mexico and the United States as its associated dance took over the East Coast thanks to Pérez Prado, Tito Puente, Tito Rodríguez and others. In the mid-1950s, a slower ballroom style, also derived from the danzón, cha-cha-cha, replaced mambo as the most popular dance genre in North America. Nonetheless, mambo continued to enjoy some degree of popularity into the 1960s and new derivative styles appeared, such as dengue; by the 1970s it had been largely incorporated into salsa.

The cha-cha-chá (also called cha-cha) is a dance of Cuban origin. It is danced to cha-cha-chá music introduced 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 shuffling sound of the dancers' feet when they dance two consecutive quick steps that characterize the dance.

In the early 1950s, Enrique Jorrín worked as a violinist and composer with the charanga group Orquesta América. The group performed at dance halls in Havana where they played danzón, danzonete, and danzon-mambo for dance-oriented crowds. Jorrín noticed that many of the dancers at these gigs had difficulty with the syncopated rhythms of the danzón-mambo. To make his music more appealing to dancers, Jorrín began composing songs where the melody was marked strongly on the first downbeat and the rhythm was less syncopated. When Orquesta América performed these new compositions at the Silver Star Club in Havana, many dancers improvised a triple step in their footwork, which produced the sound "cha-cha-chá". This new style came to be known as "cha-cha-chá".
