Song of the Seraphim is based on the passage from The Apocalypse of Saint John 4:8; "And the four living creatures, each of them with six wings, are full of eyes all around and within, and day and night they never cease to say: Holy, holy, holy, is the Lord God Almighty, who was and is and is to come".

Written in the minimalist style, the work is characterized by repetition, simplicity and almost trance-like feel. It features wave-like repetitions of the chant theme, whispers combined with singing, and a bouncy succession of staccato notes illustrating celestial worship.
