Hymn after Offertory: Ave Maria, Virgo Serena, Chant Sequence
Communion Antiphon: Primum quaerite, Heinrich Isaac
The chant sequence Ave Maria, Virgo Serena is taken from the Cantus Selecti which is a compilation of chants released in 1957 by the Solesmes Abbey. This chant highlights major events in the life of the Blessed Virgin Mary. It also inspired three major compositions in the late 1400s, most notably a setting by Josquin des Prez. The sequence was originally composed for the feast of the Annunciation.
The communion antiphon Primum quaerite is a setting by Heinrich Isaac. The text of the antiphon is: Seek first the kingdom of God, and all things shall be added unto you, says the Lord. This passage taken from St. Matthew’s Gospel 6:33. Isaac’s setting uses a stylized version of the Gregorian melody in the Soprano voice.
Heinrich Isaac (c.1450–1517) was a Renaissance composer from the South Netherlandish region. His output was rivaled only by Orlandus Lassus in number and variety of composition. Most notable of his collections is Choralis Constantinus which contains nearly 400 Gregorian chant based motets of propers for the Mass.
