Nso Nso Nso (Missa Inye Otito)

When the Eucharistic Prayer begins, the choir's role is to lead the people in the great song of the angels. E. C. Nwatu’s "Nso Nso Nso," part of the *Missa Inye Otito* (Mass of Giving Praise), does exactly this with a beautiful sense of progression. The score directs the sopranos to introduce the melody a cappella, singing the opening "Nso, nso, nso" (Holy, holy, holy) with a quiet reverence. It is a moment of stillness in the sanctuary before the organ interlude swells and the rest of the choir joins to declare the glory of the Lord of Hosts.

As the piece moves forward, the mood shifts from awe to vibrant celebration. The lyrics urge us to proclaim the Lord's holiness across heaven and earth ("Ekwusa tie ya n'igwe n'uwa"), calling everyone to recognize God's glory alongside the angels ("ndị mụọma"). By the time the choir reaches the Hosanna, the rhythm has picked up, turning into a joyful, rhythmic shout that feels right at home in a festive Nigerian Mass.

For a choir director, this Sanctus offers a wonderful balance of solemnity and energy. The transition into "Ọ dị ngozi bụ Onye bịara n'aha Onyenweanyị" (Blessed is He who comes in the name of the Lord) is bright and welcoming, lifting the congregation's spirits as they prepare for the Consecration. It is a piece that reminds us why we sing the Mass—to join our earthly voices with the heavenly chorus in unreserved praise.
