Introduction
Until the approval of The New Roman Missal by Pope Paul VI on 3 April 1969, there had existed for four hundred years a substantial unity between the texts of the Proper of the Mass contained in the Graduale Romanum and those given in the Roman Missal. The Missal, in effect, reproduced the complete texts of those sung parts of the Mass that in the Graduale Romanum are fully notated.
The Missal takes the text of the Chants of the Proper of the Mass from the Graduale Romanum, and not the Graduale Romanum from the Missal. The Missal, in fact, contains the very same texts found in the Graduale, but in the Missal they are printed without the musical notation that allows them to be brought to life in song and, in a certain sense, interprets them in the context of the liturgy. The melodic vesture of the texts functions as a liturgical hermeneutic, allowing them to be sung, heard, and received in the light of the mysteries of Christ and of the Church.
