The work is dedicated to Robert Buttimore, a friend who died during the final months of composition in Autumn 1999. The Introit opens with the first four notes of the plainchant Introit. The Introit, Kyrie, Sanctus and Agnus Dei are all developed from the plainchant Introit - Introit, Kyrie, Offertory, Sanctus, Benedictus, Agnus Dei, Communion, In Paradisum.
