Christmas tunes are a staple of the holiday season. NOEL and CAROL are two of the most popular Christmas tunes. NOEL is a four letter word that is derived from the French phrase 'les bonnes nouvelles' which translates to 'the good news'. CAROL is a five letter word that is derived from the French word 'CAROLE' which means 'a song of joy or celebration'. Both NOEL and CAROL are traditional Christmas songs that are often sung during the holiday season.
