About argentinian tango...

 

Tango is a partner dance that originated in the 1890s along the River Plate, the natural border between Argentina and Uruguay, and soon spread to the rest of the world.

   Argentine tango is a musical genre of simple quadruple metre and binary musical form, and the social dance that accompanies it. Its lyrics and music are marked by nostalgia, expressed through melodic instruments including the bandoneón. Early tango was known as tango criollo (Creole tango). Originating at the ending of the 19th century in the suburbs of Buenos Aires and Montevideo, Uruguay, it quickly grew in popularity and spread internationally. Among its leading

figures are the singer and songwriter Carlos Gardel and composers/performers Francisco Canaro, Juan D'Arienzo, Osvaldo Pugliese, and Ástor Piazzolla.

Today, there are many forms of tango extant. Popularly and among tango dancing circles, the authentic tango is considered to be the one closest to the form originally danced in Argentina and Uruguay.

On August 31, 2009 UNESCO approved a joint proposal by Argentina and Uruguay to include the tango in the UNESCO Intangible Cultural Heritage Lists.
