This is an instructional video on dancing the Tango, specifically the footwork. This elegant dance instructional goes over the Tap on '2' - Embellishment. This video illustrates tapping on the '2', if you count '1-2-3-4' for each beat. ('1' being the downbeat, '3' being the upbeat or exact middle, and '2' and '4' being the places in between or the quarter beats). It is a synchopated embellishment.
Early tango was known as tango criollo, or simply tango. Today, there are many tango dance styles, including Argentine Tango, Uruguayan Tango, Ballroom tango (American and International styles), Finnish tango and vintage tangos. What many consider to be the authentic tango is that closest to that originally danced in Argentina and Uruguay, though other types of tango have developed into mature dances in their own right.
