From Wikipedia:
"Carol of the Bells" (also known as the "Ukrainian Bell Carol") is a choral miniature work originally composed by the Ukrainian composer Mykola Dmytrovych Leontovych. Throughout the piece, a 4 note motif is used as an ostinato and was taken from an ancient pagan Ukrainian New Year's chant known in Ukrainian as "Shchedryk". The original work was intended to be sung a cappella.
The composition was premiered in December 1916 by students at Kiev University and was introduced to Western audiences by the Ukrainian National Chorus during its concert tour of Europe and the Americas. It premiered in the United States on October 5, 1921, at Carnegie Hall and was later adapted into English language version by Peter Wilhousky in the 1930s.

I offer up my three favorite versions: haunting harmonies, melodic piano instrumental and layered a cappella... and, as Joni says, "you know, there may be more" - enjoy!
