"Tu es Petrus" is a sacred motet composed by William Byrd, an English composer of the Renaissance era. The piece was composed in the late 16th century, around 1590, during the reign of Queen Elizabeth I. It was first performed in the Chapel Royal, London, and was dedicated to the queen. The motet is written for six voices, with two sopranos, alto, two tenors, and bass. It is divided into three movements, with the first and third movements being in triple meter and the second movement in duple meter. The text of the motet is taken from the Gospel of Matthew, chapter 16, verses 18-19, where Jesus declares to Peter that he is the rock upon which he will build his church. The first movement begins with a majestic and grandiose opening, with the voices singing in unison to proclaim the words "Tu es Petrus" (You are Peter). The music then shifts to a more contrapuntal texture, with the voices weaving in and out of each other in a complex and intricate manner. The movement ends with a return to the opening theme, with the voices once again singing in unison. The second movement is more subdued and introspective, with the voices singing in a more homophonic texture. The music is characterized by its use of suspensions and dissonances, which create a sense of tension and release. The movement ends with a quiet and contemplative cadence. The third movement is a joyful and celebratory finale, with the voices singing in a lively and rhythmic manner. The music is characterized by its use of syncopation and lively rhythms, which create a sense of energy and excitement. The movement ends with a triumphant and exultant cadence, with the voices proclaiming the words "et portae inferi non praevalebunt adversus eam" (and the gates of hell shall not prevail against it). Overall, "Tu es Petrus" is a masterful example of Byrd's skill as a composer. The piece is characterized by its intricate and complex counterpoint, its use of dissonance and tension, and its grandiose and celebratory character. It remains a beloved and frequently performed work in the choral repertoire to this day.
