The Septet in E♭ major, Op. 65, was written by Camille Saint-Saëns between 1879 and 1880 for the unusual combination of trumpet, two violins, viola, cello, double bass and piano. Like the suites Opp. 16, 49, 90, the septet is a neoclassical work that revives 17th-century French dance forms, reflecting Saint-Saëns's interest in the largely forgotten French musical traditions of the 17th century.
