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.
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 bandoneon.
