This arrangement is a combination of “What Child is This?” and “Carol of the Bells.” “What Child is This?” is a hymn by William Chatterton Dix set to the music of “Greensleeves,“ a traditional English folk song found in several late 16th century and early 17th century sources. “Carol of the Bells” was composed by Ukrainian Mykola Leontovych in 1904 and is based on a traditional folk chant.
