There's an evident link between the abstraction qualities and tendencies of an art from, and it's ability to travel through time, epochs, cultures and contexts with ease. Music being the most abstract art form, travels easily through all these. A musical piece createed hundreds of years ago can have immediate contemporary relenevce to a here and now, remotely similar to the one in which it was created.
Dance I think, is on the complete other side of that spectrum. Although quit frequently referred to as 'abstract', I think there can never realy exist any notion of abstraction when talking about dance, or choreography for that matter.
The mere prresence of people, being the subject matter whether one wants it or not, make it as concrete as it gets. And when looking at other forms of art it's obvious that the concrete, travels through time and different contexts In a much more clumsy and hesitant manner.
The dance of the past can be many things, but it can not truly be experienced as a relevant contemporary comment or observation.
Choreography and dance are mediums bound to their time. They make little sense outside of it.
