This article discusses some songs and hymns for Advent. The introit "Rorate Coeli," associated with votive Masses of Blessed Virgin Mary during Advent, is sung on the 4th Sunday of Advent and on other occasions such as the Expectation of the Blessed Virgin. "Vide Domine" is a piece of intense pain and sorrow. The hymn "Conditor Alme Siderum" is sung at vespers throughout Advent. The chant "Alma Redemptoris Mater" provides a bridge through Advent to Christmastide.
