"Improvisation Technologies - A Tool for the Analytical Dance Eye" (1993-1999) is a CD-ROM, commissioned by the ZKM, and co-developed by Christian Ziegler for William Forsythe's Frankfurter Ballett.
Improvisation Technologies was created for the Frankfurter Ballett, in order to instruct and inform the dancers about the body language developed by Forsythe. On the CD-ROM, he gives short demonstrations, elaborated with computer graphics. The user also sees parts of the choreography -- it is possible to move around the dancers and to study their movements.
It comprises 60 video chapters in which William Forsythe demonstrates and comments upon the essential principles of his motional language. Examples - specially danced for the CD-ROM by Frankfurt Ballet members - can be called up as required. A solo performance by William Forsythe is also included.
Commissioned by the ZKM (Zentrum für Kunst und Medientechnologie) in Karlsruhe, Christian Ziegler co-developed this exceptional interface. At V2_, in 1995, the prototype was presented from four harddisks, since this CD-ROM was still difficult to produce technically - four different video cameras had to be handled independently while image and sound had to remain synchronous.
