William Forsythe and Saburo Teshigawara showcase in their choreography willful bodies that follow an immanent logic of movement. In this way, dance achieves high complexity, extreme speeds, and a continuous flow. These qualities engage the viewer's bodily knowledge, allowing them to experience the performance through their sense of movement. It becomes clear how essential and formative the viewer's physical competencies are for their perception of the moving bodies. The study examines dance movement without imposing meanings on it. Instead, it emphasizes its willfulness and processual nature, scientifically elaborating on the terms "sense of movement" and "movement logic" derived from dance practice.
