Argentine tango is a musical genre of 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. 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.
Tango dance is essentially walking with a partner and the music. Dancing appropriately to the emotion and speed of a music is extremely important to dancing tango. A good dancer is one who transmits a feeling of the music to the partner and dancing relies heavily on improvisation.
