Today, Salve regina, Alma redemptoris mater, Ave regina caelorum, and Regina caeli appear in all sorts of liturgical and para-liturgical settings. Families teach them to their children for bedtime prayers, parishioners sing them after Vespers services before retiring home for the evening, and many music directors plan them every Sunday for a post-communion anthem or a recessional song.

Roman Catholic parish musicians will benefit from the included Vespers "cheat sheet", resources for antiphons, description of psalm tones and their relationship to proper antiphons, and nearly 70 sheet music files included here.

The Liturgy is cosmic and epic, and Hildegard wanted her community to live and believe this! Hildegard was a leader, and especially a liturgist. This is why her music was so important, as a revelation of the heavenly cosmos: the heavenly Liturgy.

The Liturgy is a point of contact between temporal and eternal, made sensibly present on earth via Gregorian chants in a myriad of ways.
