The Language of the Birds (in German: Die Sprache der Vögel), JS 62, is a theatre score for orchestra written in 1911 by the Finnish composer Jean Sibelius.

The music comprises just a single number: the "Wedding March" (in Finnish: "Häämarssi") to accompany a festive scene in Act III.

However, no production of Paul's play appears to have utilized Sibelius's music, and as such, The Language of the Birds had to wait until 21 September 1983 for its world premiere, when the Finnish conductor Esa-Pekka Salonen and the Finnish Radio Symphony Orchestra played it over yle radio.

[3] The Language of the Birds' is scored for the following instruments,[1] organized by family (woodwinds, brass, percussion, and strings): The piece is notable by Sibelius's standards in that it omits both horns and bassoons.

[5] The Estonian-American conductor Neemi Järvi and the Gothenburg Symphony Orchestra made the world premiere studio recording of The Language of the Birds in 1990 for BIS.
