Angelorum Psalat exhibits considerable rhythmic complexity and its text employs contrasting imagery of original sin and the harmony of the spheres, a common poetic device of the age. Nothing is known of Rodericus’s life, although Gilbert Reaney suggested that he is Rodrigo de la Guitarra, since Rodrigo is the only known contemporaneous musician with the same name.
