Gregorian chant is the central tradition of Western plainchant, a form of monophonic liturgical music within Western Christianity that accompanied the celebration of Mass and other ritual services. It is named after Pope Gregory I, Bishop of Rome from 590 to 604, who is traditionally credited for having ordered the simplification and cataloging of music assigned to specific celebrations in the church calendar.
