I think of choreography as a sort of natural phenomena. Something to look at and contemplate upon, like one would any other manifestation of naturally assembled elements. In that sense, a choreography has the same properties and may provide the same experience one would have when looking at the ocean, the sky, a crowded street, a flock of birds, a mountain or a group of children playing.
Bounding choreography to specific themes, narratives or messages, reduces it into something that smells like preaching or propaganda in the best case, or gossip when at its worse. And in both cases, it is unavoidably deeply manipulative. The thing I find most appealing about all natural phenomenas, is that there isn't the slightest shade of manipulation about them. The option doesn't even exist.
The récurent need of both makers and audiences to handicap the choreographic medium in such ways, has more to do with fear than anything else I feel. It's a way to find reassurance by avoiding completely the act of unbiased, open observation. I think that choreography should deal with how things are made, rather than how they look or what is the story they tell, which is always bound to be a superficial discussion about appearances, rather than an examination of the THING itself.
The damages this approach to dance making produces to everyone involved, choreographers, dancers, audiences and the art form in general, are innumerable I find.
