Following in the style of composers such as Brahms and Fauré, John Rutter’s Requiem is not strictly a setting of the Requiem Mass as laid down in Catholic liturgy. The Requiem is a musical setting of sections of the Missa pro Defunctis, the Book of Common Prayer, and the Psalms. These seven sections contain prayers on behalf of all humanity, psalms, personal prayers, and in the central Sanctus an affirmation of divine glory.
