Tango is a style of ballroom dance music in 2/4 or 4/4 time that originated among European immigrant populations of Argentina and Uruguay (collectively, the "Rioplatenses"). It is traditionally played by a sextet, known as the orquesta típica, which includes two violins, piano, double bass, and two bandoneons. Earlier forms of this ensemble sometimes included flute, clarinet and guitar. Tango may be purely instrumental or may include a vocalist. Tango is well-known across much of the world, along with the associated tango dance.
Even though the present forms developed in Argentina and Uruguay from the mid 19th century, there are records of 18th and early 19th century Tango styles in Cuba and Spain, while there is a flamenco Tangos dance that may share a common ancestor in a minuet-style European dance. All sources stress the influence of the African communities and their rhythms, while the instruments and techniques brought in by European immigrants in the 20th century played a major role in its final definition, relating it to the Salon music styles to which Tango would contribute back at a later stage.
The first Tango ever recorded was made by Angel Villoldo and played by the French national guard in Paris. Villoldo had to record in Paris because in Argentina at the time there was no recording studio.
