The score of Svyati (O Holy One), by John Tavener, for SATB choir and solo cello. Text in church Slavonic.

Quoting Tavener: "I began to write Svyati in early 1995: while sketching it, I learned that John Williams, father of Jane, my dear friend and publisher, was dying. I could not refrain from dedicating it to Jane and to the memory of her father.

The text is in Church Slavonic, and it is used at almost every Russian Orthodox service, perhaps most poignantly after the congregation have kissed the body in an open coffin at an Orthodox funeral. The choir sings as the coffin is closed and borne out of the church, followed by the mourners with lighted candles. The cello represents the Priest or Ikon of Christ, and should play at a distance from the choir, perhaps at the opposite end of the building. As is Greek drama, choir and priest are in dialogue with each other. Since the cello represents the Ikon of Christ, it must be played without any sentiment of a Western character, but should derive from the chanting of the Eastern Orthodox Church."
