Legend says that at the stroke of midnight on the evening when Jesus was born every bell on the earth began ringing joyously together. It is said there was never a sound quite like it. The song "Carol of the Bells" probably comes from that legend.
Traditionally, the song starts out soft and gets progressively louder as each voice adds tintinnabulation and then the song softly fades away. The tune for the song was written by Mykola Dmytrovich and was based on an old Ukrainian melody. The words that are used today were written by American composer Peter J. Wihousky, who grew up singing in Russian-American choirs. It was first performed in the Ukraine on the night of January 13, 1916, which on the Julian calendar is considered New Year's Eve. In the United States the song was first performed on October 5, 1921 at Carnegie Hall.
