Tango originated in Buenos Aires in the late 19th century. Modern Argentine tango is danced in both open and closed embraces which focuses on the lead and follow moving in harmony of the tango's passionate charging music. The tango's technique is like walking to the music while keeping feet grounded and allowing ankles and knees to brush against one another during each step taken. Tango is a flat-footed dance and unlike the other dances, has no rise and fall. Body weight is kept over the toes and the connection is held between the dancers in the hips.
