Just a thought: there is a dance that's improvised to music, that many of us are familiar with from childhood, and certainly from our teens, by which time it IS social dance; that arm-waving, body-writhing, jumping dance of discos, clubs and parties everywhere.
Has anyone tried it to tango music? I have, but what I do is conditioned by what I've been taught to do to tango music. But it occurred to me that it would be interesting to see what people with no knowledge of tango music would improvise to it. & then it occurred to me that this might be a good way to introduce people to tango music. The activity is a familiar one, but the music is unfamiliar, so it would be necessary to listen to it, to find the beat, the compas, and then possibly feel the melodic flow of cadencia too, and respond to it perhaps with the torso and arms. In any case, to explore this new music with the body. A teacher who knows the music should be able to suggest, by body movements, what is going on in the music, and ways to respond to it. Learning directly with the body rather than through a verbal explanation might be a useful path for people who've never listened to the music and who want to dance to it. The dance itself, the embrace and ways of movement possible in the embrace would still need to be explored, of course. & this could be extended to vals and milonga: here's something different, try and work out for yourselves what is going on. What we find out for ourselves we usually know better than something that's explained to us.
If anyone's ever tried this, or tries it, I'd love to know if it works.
