Argentine Tango -- A Brief History. The exact origins of tangoâboth the dance and the word itselfâare lost in myth and an unrecorded history. The generally accepted theory is that in the mid-1800s, the African slaves who had been brought to Argentina or their descendants began to influence the local culture.
The dance consists of a four-beat rhythm laid on top of the music of the bandurria, a 14-string instrument that evolved from the 12-string Spanish bandurria. Early versions of the dance were simple and involved only one or two people. Tinikling originated during the 1500s when the Spaniards conquered the Philippines. It was started by farmers on the Visayan Islands of Leyte. The dance has also been said to have derived from a punishment that the Spaniards practiced.
