Vocal Vibrations. Le Laboratoire, Paris. Opens March 28. Free.
From the people who brought you inhalable chocolate, here comes a high-tech singalong. Visitors start in a chamber filled with ethereal music by the composer Tod Machover. When they wander into a private “cocoon” designed by Neri Oxman, they can sing while an electronic necklace measures vibrations in the larynx, getting instant feedback as the sonic aura adapts to the visitor’s voice and a grapefruit-size “orb” vibrates in the hands. The installation will feed into a larger investigation on the healing power of the human voice. When it travels to Cambridge, Mass., in the fall, a cartilage expert will ask whether skilled humming might improve the health of joints, a neuroscientist will try to match up vocal performance and brain measurements, and a Tibetan monk will attempt to engineer a better method of chanting.
