This new sequence of words and music provides the framework for a devotional service and a wide range of choral resources for use during Advent. Structured around the great Advent Atiphons, known as the Great Os, this service of darkness to light provides readings and music to complement the Antiphons, and help us reflect on the theme of the Christ who comes to judge and save his people. The choral music offers flexibility in a wide range of styles and levels of difficulty for choirs of all standards. Congregational items include established Advent hymns and contemporary worship songs. The Advent Sequence includes music by: John Barnard, Jon Banks, George Guest, Simon Lole, Peter Moger, David Ogden, and Richard Shephard. The Advent Sequence provides a valuable addition to the music and liturgy of Advent for churches of all sizes.
