Tango originated in Argentina and Uruguay from the fusion of African and European immigrants and native peoples. It is both a musical genre and dance. Tango music traditionally features guitar, bandoneon (an accordion-like instrument), piano, and bass without wind instruments. The lyrics use complex language and metaphors. The tango dance was born in working-class neighborhoods, involving close embraces between partners with slow, improvised movements. While once prohibited, tango spread globally and is now an important dance taught around the world, especially in Japan, New York, and Europe.
