Argentine tango is a form of dance that originated in Argentina and Uruguay. It is often confused with the ballroom 'Tango' that was formalized by dance studios in North America.
Argentine tango can be seen as walking with a partner to the music, with embellishments and improvisation. It is a contact dance with no 'basic step', and instead uses strong non-verbal communication and contact. When danced in groups, it is danced counter-clockwise around a dance floor as are most traditional ballroom dances.
