Most people, when they think of Carols, will call to mind "Silent Night, Holy Night", "Hark The Herald Angels Sing" and other old favourites that have become part and parcel of our Christmas tradition. But there is a whole repertoire of medieval carols for Christmas and Easter that is just as fresh and appealing now as it was in its heyday. These are fully developed examples of a fine and contrapuntal technique written at a time when England was among the musical leaders of the world, and they are as characteristic of England's musical genius as the much better known Elizabethan madrigal.
