Descarga in the context of Tito Puente

The conga, also known as tumbadora, is a tall, narrow, single-headed drum from the Congo. Congas are staved like barrels and classified into three types: quinto (lead drum, highest), tres dos or tres golpes (middle), and tumba or salidor (lowest). Congas were originally used in Afro-Cuban music genres such as conga (hence their name) and rumba, in which each drummer would play a single drum. Following numerous innovations in conga drumming and construction during the mid-20th century, as well as its internationalization, it became increasingly common for drummers to play two or three drums. Congas have become a popular instrument in many forms of Latin music such as son (when played by conjuntos), descarga, Afro-Cuban jazz, salsa, songo, merengue and Latin rock.

The origins of the conga drum can be traced back to West and Central Africa, especially regions now known as Congo, Nigeria, and Angola. The modern version of the conga was developed by Cuban people of African descent during the late 19th century or early 20th century. Its direct ancestors are thought to be the yuka and makuta (of Bantu origin) and the bembé drums (of Yoruba origin). In Cuba and Latin America, congas are primarily played as hand drums. In Trinidadian calypso and soca, congas are sometimes struck with mallets, while in the Congos, they are often struck with one hand and one mallet.

Son cubano (Spanish: [ˌsoŋ kuˈβano]) is a genre of music and dance that originated in the highlands of eastern Cuba during the late 19th century. It is a syncretic genre that blends elements of Spanish and African origin. Among its fundamental Hispanic components are the vocal style, lyrical metre and the primacy of the tres, derived from the Spanish guitar. On the other hand, its characteristic clave rhythm, call and response structure and percussion section (bongo, maracas, etc.) are all rooted in traditions of Bantu origin.

Around 1909 the son reached Havana, where the first recordings were made in 1917. This marked the start of its expansion throughout the island, becoming Cuba's most popular and influential genre. While early groups had between three and five members, during the 1920s the sexteto (sextet) became the genre's primary format. By the 1930s, many bands had incorporated a trumpet, becoming septetos, and in the 1940s a larger type of ensemble featuring congas and piano became the norm: the conjunto. The son became one of the main ingredients in the jam sessions known as descargas that flourished during the 1950s.
