Even though present forms of tango developed in Argentina and Uruguay from the mid-19th century, there are records of 19th and early 20th-century tango styles in Cuba and Spain, while there is a flamenco tango dance that may share a common ancestor in a minuet-style European dance. All sources stress the influence of African communities and their rhythms, while the instruments and techniques brought in by European immigrants in the 20th century played a major role in the style's final definition, relating it to the salon music styles to which tango would contribute back at a later stage.
