Triforium (1975) by Joseph Young

DESCRIPTION:  60-foot by 20-foot, 60-ton concrete "poly-phonoptic" kinetic tower sculpture with lighted Venetian glass prisms and programmed sound system.

Young's original sculpture featured a 79-note glass bell Finkelbeiner Carillon as its musical component to accompany the lighting display.  The carillon had two octaves of English bells and two octaves of Flemish bells. It was disconnected in a 2006 restoration and replaced by a Compact Disc player that is programmed to provide a synchronized music and lighting program.  The original reflecting pool was also removed.Carillon definition:  A set of fixed chromatically tuned bells sounded by hammers controlled from a keyboard. Merriam-Webster
In 2017 and 2018 The Triforium Project sponsored and produced live music performances, including special lighting for the sculpture.See also "Triforium" @ Google Arts & Culture
