The Vocal Chorder

Opera singers can use the Vocal Chorder, a large interactive instrument, to add new elements to their performance. The device allows performers to interactively accompany themselves through pushing, leaning on, and bending steel wires. Audience members can also use the instrument to interact with the operatic voice. When a person steps into the Vocal Chorder, its wires enable full-body interaction to explore the sounds and the interactive pyramid projected in front of the performer. It is a visualization of the child in Ray Bradbury's short story "Tomorrow's Child," born in another dimension and perceivable by its parents only as a pyramid.
