Carol of the Bells

A malleable song that conjures joyful exuberance or aching melancholy depending on the context, this year “Carol of the Bells” conveys both. The 100th anniversary of its debut American performance was Oct. 5, and it is being celebrated as one of Ukraine’s shining contributions to world culture at a time when the country is enduring a devastating war with Russia that is about to stretch into its 11th month.
