Regina Caeli - Gregorian Chant (Simple tone)

"Regina Caeli" (Queen of Heaven) is a musical antiphon addressed to the Blessed Virgin Mary that is used in the liturgy of the Roman Rite of the Catholic Church during the Easter season, from Easter Sunday until Pentecost. During this season, it is the Marian antiphon that ends Compline (Night Prayer) and it takes the place of the traditional thrice-daily Angelus prayer.
Lyrics:
Regina caeli, laetare, alleluia;
Quia quem meruisti portare, alleluia,
Resurrexit, sicut dixit, alleluia:
Ora pro nobis Deum, alleluia.
Queen of heaven, rejoice, alleluia.
The Son you merited to bear, alleluia,
Has risen as he said, alleluia.
Pray to God for us, alleluia.
