The European Continent spiraled into darkness after the fall of the Roman Empire in the fifth century. The following millennium witnessed the descent of society, the church, and civilization into an age of corruption. Monophonic melodies or plainchant defined music during this age, and organum—a monophonic melody with another line sung at a fixed pitch, notably a perfect fourth or fifth—became the leading trend in music as the Renaissance approached.
The piece begins with a church chime defining the rule and power of the church during the Middle Ages. The first melody is heard in the bassoon and cello. It carries the form and feel of plainchant that would be heard in a monastery during that time. The melody then transfers to the period-correct recorder with the bassoons following in organum fashion. Chimes are ever present, as the church that watches and lords over all. The movement exhibits a small sense of hope in the woodwinds, but they are overtaken by the swirling chord progression as the church spins down into the depths of corruption and evil. The recapitulation of the melody and the final church bell remind us that darkness continues to cover Christendom.
