The Twilight Chorus is new vocal work composed by Pete M. Wyer. Inspired by MIT professor Shigeru Miyagawa’s theory that human speech evolved from birdsong, Wyer’s score features slowed-down transcripts of birdsong field recordings adapted for a choir of 16 human voices. During the performance, singers move through the Garden individually before converging as a chorus.

The composer, Pete M. Wyer, and Professor Shigeru Miyagawa made brief presentations between two 20-minute performances.
