One of the interesting things about tango is how broad it is. Right now, I'm saying this from a vocabulary perspective. At first glance, it seems limiting because we're always in the same embrace. And so, you cannot do underarm turns and things like that. But I think tango is like haiku: when you add some rules, you also begin to plumb the depths of the possibilities that remain.
Tango is probably one of the only social dances where it would not be uncommon to have both people sometimes on the same foot and sometimes on the opposite foot for extended periods of time, sometimes leaning towards each other (this video), sometimes leaning away (see the colgada video).
(From the website): Created in July, 2009 by Erskine Maytorena, a third generation tango musician and opera singer, QTANGO performs authentic Argentine tango arrangements as often as two to three times a week throughout the Southwest for tango dancers and listeners.
