SATB and Organ. A very cool and interesting organ part - mystical and not difficult for the choir to learn. Short enough to be used as an introit, but also perfect for an anthem. Also great for a Lessons and Carols service. Alternate English text for the first half (up until the Gloria in excelsis).
Today Christ is born. Today the Savior appeared.
Today on earth the angels sing, archangels rejoice:
Today the righteous rejoice, saying:
Glory to God in the highest, and on earth, peace, goodwill to all.
