The Expanded Chamber: Orchestral Fly

3D Chamber music installation. "The Message of Music", Palais Harrach, Kunsthistorisches Museum. Vienna. 1996.
Christian Moeller and Wilfried Seipel

Within an orchestral performance, the discrete tonal characteristics of individual instruments are not discernable to non-musicians not trained to perceive them. Listeners cannot concentrate on one isolated instrument from an entire orchestra for more than a few moments. The possibility of filtering, isolating and intensifying the musical qualities of individual instruments enables the listener to discover new, amusing and fascinating levels of variable acoustic perception during a concert performance.
This installation enables the visitor to experience, via headphones and monitor, a visual and acoustic virtual space. The chamber music players are seemingly in concert. The visitor navigate the simulated music chamber using a sensor which corresponds to the visitor’s changing location in the virtual space, allowing him to listen to specific instruments as if he were next to them.
Without touching the original scores, this creates a new kind of musical perception only possible in this virtual sensory environment. The installation allows the listener to have the auditory perceptual perspective of a "fly," buzzing at any speed around the chamber from musician to musician, listening closely to nearby instruments.
