Opera Greets the Morning at the Prototype Festival

“These people are not drunk,” a choir in quirkily customized blue robes sang on Saturday, “because it’s nine in the morning.”

Watching these smiling performers in the light-flooded Space at Irondale in Brooklyn, I was surprised to discover that this startlingly contemporary sentence was a translation of a biblical verse, Acts 2:15. And it was an appropriate sentiment at, yes, about 9 a.m.

In “Terce,” presented as part of this year’s Prototype festival of new opera and music theater, about three dozen choir members were praying, as Christians have done at that hour from the era of the early church. The work adapts and takes its name from the traditional liturgy for 9 o’clock, the time when the Holy Spirit is believed to have appeared to the apostles on Pentecost.

In Brooklyn, there’s a twist, if not a wholly unfamiliar one: The divinity being celebrated in this folk-soul-gospel-medieval amalgam is, according to the script, a woman, a mother, “an undeniably female creator.”

Politically charged, scrappy, stirring, deeply earnest: “Terce,” created and led by Heather Christian, embodies Prototype, now in its 11th season and organized by Beth Morrison Projects and HERE, the arts center in SoHo. (The festival runs through Sunday.)
