Robert Dunn's Workshop and Its Influence on Judson Dance TheaterEunsook ChoProfessor of DanceChung-Ang UniversityThe term ?post-modern? came into existence in American dance in the early 1960s. The first example of post-modern dance was performed by the Judson Dance Theater which was composed of many choreographers who came out of the choreographic workshop led by musician Robert Dunn.Robert Dunn, accompanist at Cunningham?s class and other modern dance studios, studied with John Cage at the New School for Social Research. Dunn was influenced by Cage and applied Cage?s procedure, especially chance methods, to his dance composition class. Using the music of John Cage and other avant-garde composers, Dunn taught improvisation. Furthermore, he frequently suggested that students use Erik Satie?s repetitive time structures in their choreography.Dunn also demonstrated and gave assignments for choreographing and improvising solos. At times he proposed changes in students? work which his disciples often incorporated into their own choreography and improvisation. Students set up a group session forum, shared their basic ideas and improvised expanded solos. Upon the completion of their presentations, the students with due diligence scrutinized each others? work and devised further methods of enhancing their future performances. The study illustrates the development of the post-modern dance and Robert Dunn?s workshop. Also, Dunn?s influence on Judson Dance Theater will be explained.
