Symphony on a French Mountain Air

25, is an orchestral composition written in 1886 by Vincent d'Indy.

As indicated by the title, d'Indy took the principal theme from a folk song he heard at Périer overlooking the Cévennes mountains (hence the work's alternative name, Symphonie cévenole).

Originally conceived as a fantaisie for piano and orchestra, the symphony is unusual in that it is scored for a prominent (but never dominant) piano part together with orchestra, and has acquired the label sinfonia concertante from some critics.

It consists of three movements and lasts just under half an hour: The symphony begins with an evocative melody played first by a cor anglais.

The work was dedicated to Marie-Léontine Bordes-Pène, who was the soloist at the premiere in Paris on March 20, 1887.
