Entering the Seminary

I met a young guy who'd entered the seminary to become a priest and we got to talking over a few drinks. He was family of a friend of mine, and I didn't want to be rude and ask a bunch of uncouth questions about things I've always wondered when men enter the priesthood. I settled on one question that wasn't too rude or presumptuous, and waited for my chance. When my friend got up to go to the bathroom I asked: "Do they have any classes to teach priests how to sing?" During church services priests have to belt out a few lines and universally they're pretty terrible. He said there's one class that they can take relating to choirs and singing in front of crowds, but it's an elective. The whole premise of elective classes in seminary was too much to process.
