This film transforms a piece of music into a visual and examines the role of humans in this performance of sound and light. After a prologue in which composer and conductor Beat Furrer is shown obtaining and arranging a score by Schumann, its performance is the film's actual theme: As the notes pass through the picture, the musicians of the Klangforum Wien ensemble appear and disappear according to their acoustic contribution. The result is a choreography of sound, the music's transience and vastness is turned into a ballet of bodies which, somewhere between presence and absence, commemorates the instability of being as a dialectic micro-spectacle.
