The luxury of a morning in after a milonga, to enjoy a slow coffee in the sunshine and remember the partners you shared the previous evening with: the tall one who delighted in a fast vals tanda, the short round body that fitted itself so memorably and fluently into the slow grave music of some Tipica Victor, the older Italian who enjoyed so much the elegance of a tanda of De Angelis early when the floor was empty. I enjoyed dancing with her a few times: she spoke no English and very little Spanish, and I guess her conversations (with Pedro Sanchez among others) were in Italian of sorts, possible because it was the language of at least one of the parents of many living Argentines, and anyway Italian and Spanish are not so different.
And some local partners: the one with tattoos and tight jeans (I didn't notice the jeans until she stood up) seemed out of place in a traditional milonga, not so much because of the jeans (she looked elegant enough) but as she clearly preferred an open/close embrace and the kind of dance that goes with it. & then a wonderful lady who talked and laughed happily between dances and then simply melted into four tangos of D'Agostino (with Angel Vargas, as she reminded me): the floor just seemed to open up around us. Then that slender partner: at first we couldn't quite agree on the beat, then it began to settle down and by the fourth tango the shared warmth of the embrace was the only thing that existed, constant and unchanging, so much at one with partner that the music and the floor just fell into place around the embrace. Then we walked away from it; that, after all, is the agreement.
Dance and music: musicians leave hard evidence of what they've made, but dancers leave nothing but memories, and perhaps an unquantifiable change of consciousness created by the few moments' experience of intimacy with a partner, who may be a complete stranger.
Memories, and now videos I guess. Actually I wonder if video could be misleading for intimate social tango as it emphasises watching and performance rather than direct experience. It's great that people learn from it, but learning from video is likely to be partial. You see only the obvious and you may really need someone with long experience to show you, physically or even in the video, things that might not be immediately obvious. Video tends to minimise the physicality and you might end up with the bare bones of a dance, without its seductive flesh. I hope video doesn't end up degrading the close embrace dance.
