Missa De Angelis, or Mass VIII, is one of the best known Gregorian Chant Masses today. As with most of these Mass units the various pieces, Kyrie, Gloria, etc. were not composed together but rather grouped at a certain point in history, assigned a number and title. This particular Mass seems to have been gathered together in the 18th century, though the Kyrie is likely a 15th century Norman composition, the Gloria from the 16th century, the Sanctus again from Normandy in the 11th or 12th century and the Agnus Dei, 15th century, from the Rouen area of N. France. Most Masses are named for a “trope” that was sung before or after the mass, but this is one is unique and takes its name from the tradition of celebrating a Mass in honor of the Holy Angels on Mondays. This was a devotion especially practiced by the Franciscans.
It is interesting to see the characteristics of the various pieces here. The Kyrie and Gloria in Mode V and the Sanctus and Agnus Dei in Mode IV. The Kyrie and Sanctus, melismatic in style with the Gloria and Agnus Dei less so. And really with the exception of the Gloria it is not a “simple” mass so it is interesting that it has become one of the well-known favorites in many churches, not to mention one of the standard Masses used in the Vatican. Having been assigned as a “Festive Mass” I think there is a certain feeling of celebration attached to it and certainly we see that reflected in the chant throughout. For example the 12-note jubilus at the outset of the Kyrie, the continuous rise and fall of smaller melismas and repeated notes in the Sanctus, and the many torculae in the Agnus Dei. In celebration of the anniversary of the dedication of our church we sang this Mass on Sunday and it brought a real sense of joy to the morning.
