Arvo Pärt’s Salve Regina is a contemplative setting of the Marian antiphon for mixed choir and organ, lasting approximately 10–12 minutes. A quiet, steady organ pulse supports restrained choral writing that gradually expands from unison into as many as eight independent voices. Its recurring 3/4 metre follows the natural rhythm of the Latin text, while the music progressively becomes denser, darker, and more concentrated before reaching a powerful but controlled conclusion. Characteristically economical in its materials, the piece depends upon excellent tuning, sustained breath, rhythmic steadiness, and a unified choral tone rather than overt virtuosity
