[The U.S.C.C.B.] announced that diocesan bishops may permit the gradual introduction of the musical settings of the people’s parts of the Mass from the new Roman Missal in September. Primarily this affects the the Gloria, the Holy, Holy, Holy and the Memorial Acclamations.

Some suggested that the various acclamations could be more effectively introduced throughout the fall, so that when the full Missal is implemented on the First Sunday of Advent, the congregation will have already become familiar with the prayers that are sung.
