This work seems to have had a liturgical function, appearing as the only polyphonic item in a Gradual of Sarum chant, and is based on a cantus firmus in the middle voice. The musical style features a lively top voice. Only brief, the work has great charm; the pleasing arch structure is given some fine surface detail in the form of a four-against-three rhythmic group, a false relation (B flat against B natural) and a decorative group of 5 notes in the time of 4 at the final cadence.
