These three motets are settings of hymn texts by the influential theologian and writer, Thomas Aquinas. O Salutaris Hostia (O Saving Victim), Panis Angelicus (Bread Of Angels), and Tantum Ergo (Hence So Great A Sacrament) each pertain to the Eucharist – a central aspect of Christianity. The chant melodies of these texts are layered with other material (both derived from the tune, and freely written) in a similar fashion between each piece to create linked, but unique modern textures. Each uses predominately the same pitches, but with different use of modality originating from each chant theme producing different colours in the sound world.
