Verdi Quattro pezzi sacri

The Quattro Pezzi Sacri, or Four Sacred Pieces, are choral works by Giuseppe Verdi.

Written separately and with different origins and purposes, they were nevertheless published together, in 1898, and are often performed as a cycle in this sequence:

Ave Maria (unaccompanied chorus, in Latin, composed 1889)
Stabat Mater (orchestra and chorus, in Latin, composed 1896-1897)
Laudi alla Vergine Maria (unaccompanied female voices, in Italian, composed 1886-1888)
Te Deum (orchestra and double chorus, in Latin, composed 1895-1896)

The "Ave Maria (sulla scala enigmatica)" uses the enigmatic scale.
