USCCB • “Principal Music Books for the Eucharist”
The principal books of music for the Eucharist were recently (re-)confirmed by the United States Conference of Catholic Bishops.
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.”
