Cunningham wrote that the choreography consisted of 32 phrases that were combined, using chance operations. Many of them featured unbalances, either by a single person or in combination. “The phrases are set; the unbalances have a certain freedom.” The motif of “unbalances” recurred often, with people tilting, even to the point of falling. Thus, several times three men leaned against each other until two of them fell to the floor, and so on. Walter Zimmermann’s music, Self-Forgetting, based on a text by Meister Eckhart, was scored for violin, bandoneon or harmonium, glass harmonica, cowbells, and voice; other instruments could be added. Marsha Skinner’s décor was based on one of series of small chance landscapes she had recently painted. The costumes were in the same earth colors, with a red stripe running down one side of the body and along one leg. "Change of Address" was commissioned by the University of Texas, Austin.
