Antonio Vivaldi’s Nisi Dominus RV 608 is a sacred vocal work composed in the early 18th century, likely during his tenure at the Ospedale della Pietà in Venice. Set to Psalm 126 (127 in the King James Bible), it is a solo motet for contralto, strings, and continuo, showcasing Vivaldi’s signature blend of expressive lyricism and virtuosic flair. The piece, structured in nine movements, alternates between introspective arias and dramatic recitatives, with highlights like the hauntingly beautiful “Cum dederit” and the fiery “Sicut sagittae.” It reflects Baroque religious music’s emphasis on emotional depth and divine contemplation, tailored for the talented female musicians of the Ospedale.
