Ballroom tango is a ballroom dance that branched away from its original Argentine roots by allowing European, American, Hollywood, and competitive influences into the style and execution of the dance.
The present day ballroom tango is divided into two disciplines: American Style and International Style. Both styles may be found in social and competitive dances, but the International version is more globally accepted as a competitive style. Both styles share a closed dance position, but the American style allows its practitioners to separate from closed position to execute open moves, like underarm turns, alternate hand holds, dancing apart, and side-by-side choreography.
