Missa Orbis Factor(Ordinary Time)

This score brings together the classic Gregorian chant settings of the Mass, specifically the *Missa Orbis Factor* traditionally sung during Ordinary Time, alongside the solemn *Missa Pro Defunctis* for requiem Masses. For Nigerian Catholic choirs, these plainsong melodies offer a profound connection to the universal Church. Singing these chants requires a unified, flowing vocal tone, as the unmetered sol-fa notation guides the choir to breathe and move together as one voice.

The sheet covers the essential Ordinary parts—Kyrie, Gloria, Sanctus, and Agnus Dei—each carrying its own distinct spiritual weight. The *Gloria* bursts with reverent praise, while the *Agnus Dei* calls for a gentle, pleading delivery. The inclusion of the Requiem introit ("Requiem aeternam") provides a comforting prayer for eternal rest, making this a highly versatile resource for both regular Sunday liturgy and funeral rites.
