My setting of Tantum ergo was written to complement my setting of O Salutaris for performances at Benediction. It can of course also be performed at communion services. While both pieces share the same key (D major), Tantum ergo is based on a changing metrical pattern with 5/4 used in alternate bars. To the four vocal parts in verse 1 an additional soprano line is added – in the manner of a descant. Its devotional character and uncomplicated idiom should appeal to choirs of most abilities.
