The Agnus Dei is the last section of the Catholic Latin Mass that was regularly set to music in the Renaissance and Baroque periods (c. 1400 – 1750). Agnus Dei means, “lamb of God” and was usually reserved for the more beautiful passages of music written for the different movements of the mass. This is a setting from the Mass in B minor by J.S. Bach from the later baroque period, by this time there were many instruments used as accompaniment to the singing, whereas in the early Renaissance the music was strictly written for voices only.
