ABSTRACT
What do I see when I watch somebody dance? Obviously, a dance expert or a dancer would see the dance in a very different way than I do. Paying attention to the relevant features, he or she would be able to predict the next movements and therefore know where to look next and recognize a surprising move or a simple fault, whereas I only see a series of elaborate movements, surprised by their order and, it is to be hoped, pleased by their aesthetic expression.
