Gregorian chant

Also called " Old Roman chant ", this is one of the earliest surviving styles of music in Western Europe attributed to Pope Gregory the Great. Gregory probably had little to do with the surviving chant, as the chants that survive in manuscripts date from the 11th to the 13th centuries, and Gregory died in the year 604. The surviving chants are modal with monophonic melodies with freely-flowing, unmeasured vocal lines. Most chants belong to the Mass or to the daily offices.plainchant, the modal chant of early Christian and continuing catholic worship and its derivatives, is often known as Gregorian chant, after pope Gregory the Great, St. Gregory, to whom the attempt at standardization of the chant in the late 6th century is attributed.
