The Quattro pezzi sacri (Italian pronunciation: [ˈkwattro ˈpɛttsi ˈsaːkri], Four Sacred Pieces) are choral works by Giuseppe Verdi. Written separately during the last decades of the composer's life and with different origins and purposes, they were nevertheless published together in 1898 by Casa Ricordi. They are often performed as a cycle, not in chronological sequence of their composition, but in the sequence used in the Ricordi publication: They were first performed together (without the Ave Maria) in a concert by the Paris Opera on April 7, 1898.
