The church has had a long association with music and musicians. The funeral of Frédéric Chopin took place in the church, and the composers Camille Saint-Saëns and Gabriel Fauré each held the title of the church organist. The church has a celebrated pipe organ, located in the tribune over the south entrance to the church. It is contained in a very ornate case with sculpted angels, spires, and other ornament harmonised with the decor. The organ was built by Aristide Cavaillé-Coll in 1845. It was restored by Cavaillé-Coll's successor Charles Mutin in 1927, who also extended the manuals to 56 notes. Tonal modifications were carried out by Roethinger, Gonzalez-Danion, and Dargassies in 1957, 1971 and 1988 respectively. :.A smaller organ from the same period is located in the choir.
