Cavatine, for trombone and piano in D flat major, op. 144

The Cavatine for Trombone and Piano, Op. 144, is a chamber music composition by French composer Camille Saint-Saëns, written in 1915. The piece was dedicated to George W. Stewart, a trombonist and the musical director of the 1915 World's Fair in San Francisco, where Saint-Saëns had participated in several concerts. Composed immediately after Saint-Saëns' return to Paris from the United States, the cavatina showcases the lyrical and vocal qualities of the trombone, despite its technical demands. The work was well received by Stewart and has since become one of the most popular solo pieces in the trombone repertoire.
