One of the most fascinating of all dances, the tango is a sensual ballroom dance that originated in Buenos Aires, Argentina in the early twentieth century. Tango is usually performed by a band and a woman, expressing an element of romance in their synchronized movements. Originally, the tango was performed only by women, but once it spread beyond Buenos Aires, it developed into a dance for couples. The popularity of the tango has greatly increased over the years. Argentine Tango is much more intimate than Modern Tango, and is well-suited to dancing in small settings. Argentine Tango retains the intimacy of the original dance.
