Told from the perspective of the dancers, »Processing Choreography: Thinking with William Forsythe's Duo« is an ethnography reconstructing the dancers' activity within William Forsythe's »Duo« project, written legibly for readers in dance studies, the social sciences, and dance practice. Considering how the choreography of »Duo« emerges through practice and changes over two decades of history (1996-2018), Elizabeth Waterhouse offers a nuanced picture of creative cooperation and institutionalized process-arguing for choreography as a nexus of people, im/material practices, contexts, and relations. As a former Forsythe dancer herself, the author gives novel insight into this choreographic community.
