A Christmas carol that allows antiphonal singing, of a sort. It tells you everything you need to know about what happened at the Nativity.
Why waste time on the usual boring French Christmas carols, when there are weird ones like la Marche des rois waiting to be learned?
A 15th-century Christmas carol with a haunting minor/modal melody. Weirdly dreamlike. It may be compared with our "Twelve Days of Christmas."
