antiphon

Between the two versions of “Spiritus sanctus vivificans vita,” an antiphon by Hildegard von Bingen, for example, or between that antiphon’s simplicity and the angular density of George Enescu’s “Fantaisie concertante.”

“If you strip it down and go back to what the form should be,” Mr. Skinner said, “it’s about the size of a large-scale votive antiphon, the staple compositional endeavor of most composers.”

As Scott Metcalfe, the ensemble’s director, said in remarks from the stage, that single antiphon constitutes the complete works of Chamberlayne.

“Mass” begins with an intentionally grating Antiphon: “Kyrie eleison,” with solo voices singing the Latin words entwined with percussion instruments; the complexity increases over two fidgety minutes, with prerecorded elements played through speakers placed around the hall.

In “O Antiphon Preludes,” Muhly comments, sometimes with enthralled sweetness and sometimes with exuberance, on the seven “O” Christmas antiphons of Advent.
