It doesn't have much of a beat, the kids can't dance to it and it's sung in a dead language. But Gregorian chant seems to be the hottest thing in sacred music right now.
Consider the following:
• The wildly popular "Halo" video games use Gregorian chant (sometimes called plainsong) as background music.
• Universal Music Group, the record company best known for such acts as Amy Winehouse and Snoop Dogg, recently signed a group of Viennese monks to record an album of Gregorian chant.
• The Middle Ages chants can even greatly reduce stress, British researchers have reported.
After a public relations push by Pope Benedict, who wants Gregorian chant restored to its "pride of place" in the liturgy, a plainsong renaissance is percolating among U.S. Catholics, as well.
Nearly 200 scholas -- choirs that sing plainsong -- have popped up nationwide, many in the past five years, according to the Church Music Association of America (CMAA).
Sacred music seminars that once drew 40 to 50 people now lure hundreds of Catholic musical directors, organists and singers. And priests-in-training in seminaries across the country are increasingly asking to be educated in the intricacies of Gregorian chant, said William Mahrt, CMAA president and sacred-song expert.
