“In the beginning you improvise only the order of the details and their rhythms. Then you change the order and the rhythms and even the composition of the details. This must not be premeditated, but dictated by the flow of your own body. You must find this spontaneous line of the body, which is embodied in the details and goes beyond them but which at the same time maintains their precision. If this precision is absent, then it is useless and the result can only be a sort of prisoner.”
