Hockets for Two Voices by Meara O'Reilly is a captivating vocal piece that uses a form dating back to the Middle Ages, hocketing, in which two singers alternate notes in rapid succession. The result is a rhythmic interplay that blurs the boundaries between the voices, creating hypnotic, interlocking motifs. Performed by Linnea Sablosky and Mingjia Chen, these minimalist yet complex songs explore the infinite field of perception and new musical interfaces.
