“The Vatican Edition … contains absolutely all that is needed for the exact rendition of the liturgical chant.” —Sacred Congregation of Rites (1911)
Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”
