If Pope Benedict XVI’s recently articulated personal preferences hold sway, traditional music like Gregorian chant will become more prevalent in the Roman Catholic Mass. “The pope’s comments raise certain questions: What is sacred music supposed to sound like? And what’s wrong with new music in church? It’s a debate that has raged since 1963, when Vatican II reforms brought contemporary music to Catholic churches. Just as the Latin Mass almost immediately disappeared amid attempts to modernize, chants gave way to guitars and snappy folk tunes.”
