The meaning of the word 'Cadencia' has always provided food for thought in Arg. Tango. I remember swapping an English class for a Tango class with Arg. dancers/teachers and they also were perplexed and asking for a translation of the word 'cadencia'.. my advice to them was just to keep that term in Spanish and show examples of it's meaning... I'm not saying that I'm an expert on this nor even that I have the real meaning of the word nailed down. But that being said, what 'cadencia' means to me is the attitude and handling of the whole body of the dancer during the dance... that the dancer reflects, sings, interprets the music with his/her whole body...not just from the waist down. For an example, I am positing this video of two Japanese dancers... I used to think that only Argentines have cadencia but have been persuaded that this is just not true...here are two dancers from another country and I have not yet researched enough to know if they've been to BsAs...they certainly look it... dig the cadencia!
