A purer example of modernism would be the dances of Merce Cunningham. No emotion, no eye-contact, no display, just moving about moving. Merce Cunningham Dance Company. With modernism, the end is movement itself. If you come to a modernist work expecting to be moved by references to human emotional life you will be sorely disappointed.
Movement becomes patterns of difference in relation to predecessor texts and traditions.
The title is, at least, a triple pun. We are denied modernist closure by means of the juxtaposition of short, unrelated, stylistically distinct sections. Throughout, the inter-textuality of Tharp's work is evident as quotes from other choreographer's works pop up at unexpected, but frequent, intervals. Rather than exploring the capacities of the medium, Tharp is commenting on the forms and mores of ballet itself by putting it's tradition in a multi-textual context. It is not a dance about dance, but a ballet text about the text of ballet itself.
