Recently I was trying to remember what entrega is. Literally it means 'handing over', 'surrender', but I know it has a particular meaning in tango. My usual research method turned up this page, dated two years ago; there are some interesting comments too. There were never many posts on the Chemin du Tango blog, and it hasn't been updated since last year, but the posts are interesting; come back soon, Chemin du Tango.
Chemin du Tango's writing about entrega is a great account of... well, of almost a non-event, but nevertheless of something wonderful, something really indescribable. But her non-description seems to be a good indication of what a leader should aim to give his partner. (So it's not an assault course of waved and waving limbs that they want, not a lively good time, not an aerobic session, not even a Q&A? Just...)
I must have read about entrega first on TangoandChaos where there's a whole page on it, including a great video and a wonderful photo of '...three of the world’s best tango dancers'. Tangoandchaos says that 'What the people of the clubs are really looking for is entrega. In fact, you could say that “entrega” is the whole point of tango'. He adds that this kind of tango '... has become buried under a step and figure oriented dance that’s performed with one eye on the mirror and the other eye on the audience. A tango designed to impress as many people as possible in a two-minute YouTube clip...'
Some things are easier to define by saying what they aren't. I'd be grateful if anyone out there can tell us more. Is it really that important?
