Question: I’m curious about Gregorian chants. Who was Gregory?
Answer: There were 16 popes named Gregory, but the one who lent his name to the chants was Pope Gregory I, also known as Gregory the Great (540?-604). He was the father of the medieval papacy and a tremendous influence on his time. Gregorian chant proper is a body of music, purely vocal and ecclesiastical, that evolved from the papal choirs of the fifth and sixth centuries. It was codified in the time of Gregory I and stands as the basis for all Gregorian music.
