rigid distinction between a sung Mass and a low Mass in the Roman Rite was abandoned in the 1969 revision of the Roman Missal. The General Instruction of the Roman Missal even states: "It is very appropriate that the priest sing those parts of the Eucharistic Prayer for which musical notation is provided." Under the heading "The Importance of Singing", it says: "Great importance should therefore be attached to the use of singing in the celebration of the Mass, with due consideration for the culture of the people and abilities of each liturgical assembly. Although it is not always necessary (e.g., in weekday Masses) to sing all the texts that are of themselves meant to be sung, every care should be taken that singing by the ministers and the people is not absent in celebrations that occur on Sundays and on holy days of obligation."
