The tango is a social dance and a rioplatense genre (from the Río de la Plata)  that originated at the end of the 19th century.

​

As a rhythmic form, it most often refers to a two- or four-beat measure with a strong beat, but with a wide range of tempos, figures and rhythmic styles that vary greatly according to the period and the orchestra.

The tango is a ballroom dance that is danced by two people. It is an improvisational dance, one partner guides the other, who follows, letting his weight go naturally in the walk, without trying to guess the steps.
