One of the prayers contained in the recitation of the Rosary and one of the best known antiphons of the Gregorian repertoire today. As well as being part of popular devotions, it is included in the liturgy of the divine office. This is the solemn tone, a more elaborate melody than the one the people usually know and sing, reserved for the particularly solemn days of the liturgical year.
