This duet of unusual instrumentation was written for the composer�s sister-in-law and husband. Based upon the popular hymn tune (also known as �Dix�) of the same name, the work presents four subtle variations of the melody. First published in 1830, the tune by Conrad Kocher is also sung to the text �As With Gladness Men of Old,� which tells of the visit of the Magi. William Henry Monk revised the hymn at some point and it is this version that appears in hymnals today.
