Mario Castelnuovo-Tedesco (1895-1968) was an Italian composer of remarkable productivity and versatility, equally at home writing for the concert hall, opera house, and film studio. After emigrating to the United States in 1939, he became a central figure in Hollywood's golden age while maintaining a serious concert career, composing hundreds of works across every genre. His Jewish faith informed much of his later output, and he brought the same gift for lyrical melody and harmonic sophistication to sacred texts that made his instrumental music beloved by performers worldwide.
Castelnuovo-Tedesco's Sacred Service stands as one of the major twentieth-century contributions to the liturgical choral repertoire, combining deep spiritual conviction with the compositional craft of a master. For choral directors, his work offers the rare combination of musical substance and genuine singability; the writing never feels academic or imposed, but rather grows naturally from the text and the traditions it honors.
