The Tango originated in the bordellos of Buenos Aires, Argentina, and is done in a slightly different manner than other dances. The hold is very different, with the lady's arm under the man’s, which creates a tighter hold for a quick staccato action and stylized poses.

The American Style Tango is a progressive moving along the line of dance using body movement. A staccato movement of the feet and flexed knees highlight the dramatic style of the Tango.
