The article discusses the Gregorian chants that can be sung by people in congregations. According to the author, previous objections before prevented the faithful to sing the ordinary chants. The author suggests ordinary chants that most people can sing at the mass including "Sanctus XVIII," "Agnus XVIII," "Kyrie XVI," the "Credo III," and "Gloria VIII." These chants can be performed to fulfill the mandate of the church to sing the mass, and not just to sing during the mass.
