SANCTUS

"Sanctus" by Charles Okeke (Halogen) is a reverent Latin setting of the Holy, Holy, Holy, composed for Catholic liturgy. Written in solfa notation, the piece captures the majesty of the heavenly chorus praising God. The score includes a dedication to the St. Cecilia Angelic Voice Choir at the St. Joseph the Worker Chaplaincy, UNIZIK, grounding it in the vibrant university choir culture of Nigeria.

It is sung during the Eucharistic Prayer at Mass, right after the Preface. The choir leads the congregation in this ancient acclamation, moving from the solemn declaration of God's glory ("Pleni sunt caeli et terra") to the joyful "Hosanna in excelsis." The familiar Latin text connects the local worshipping community to the universal Church.

The arrangement features a distinct solo line that introduces the "Hosanna," building anticipation before the full choir joins in with a soaring descant. This dynamic shift elevates the worship experience, drawing the faithful deeper into the mystery of the Mass as they prepare for the consecration.
