Based on the Christmas Introit Puer Natus Est Nobis in both text and tune. The 18th century hymn text is by John Morrison. The tune is original, based on the Introit melody from the Liber Usualis (or Graduale Romanum, or Gregorian Missal, for that matter). Incidentally, originally, I wrote the tune in a major key, realized later that this would look and sound a lot better in the mixolydian mode.
