The First Noel is a traditional English carol, often said to come from Cornwall, and it was first printed in the early 19th century in collections of old carols. Noel, spelled Nowell in many British books, comes from the French Noël, Christmas.
Its many verses tell the Christmas story from the shepherds in the fields to the wise men following the star. Every phrase of the tune has the same shape - it starts low, climbs the scale to the high note and falls back - which is why it is so easy to remember, and why the long carol never feels hurried.
The notes on this page follow Christmas Carols New and Old, the Victorian collection edited by Henry Ramsden Bramley and John Stainer and published by Novello, where the carol is printed in D major as The First Nowell.
