Tango

I've never watched the show Dancing with the Stars, but the algorithm sent me this intriguing video from the show's recent season finale. Mark Ballas and Derek Hough show us how the original Argentine tango is done. When the dance was developed in the 19th century, it was done by two men. An article at E News says it was because men "outnumbered women in their communities at the time." Commenters at YouTube are a bit more forthright and tell us that women just weren't welcome at community events, which makes more sense.

Ballas and Hough are the same size and have the same high skill level, so they look like mirror images while dancing. And their technical perfection doesn't interfere with the emotional power of the dance. The two have known each other since they were 12 and had the same dance teacher, so their synchronicity shouldn't be surprising.
