Alleluia: Tu es Petrus (there is another setting in Book 3)

This powerful SATB setting of the Gospel Acclamation Alleluia uses the Latin text from Matthew 16, where Christ declares Peter the rock upon which his church will be built. Isaac’s music powerfully conveys the sense of authority and divine promise within the text. The composer’s skill in setting sacred texts is evident in this motet, which is suitable for liturgical occasions when a strong affirmation of faith is required. The contrapuntal writing and homophonic passages create a rich texture, making it an effective choice for a choir looking to explore Renaissance sacred polyphony.
