The alphorn is a wind instrument consisting of a natural wooden horn of conical bore and a cup-shaped mouthpiece, and it is used by mountain dwellers in Switzerland. This instruments are carved from solid softwood, and since they don't have lateral openings, the harmonic series of the open pipe are natural. Rossini introduced the melody Ranz des Vaches, a traditional melody from French Switzerland, into his opera William Tell, and Brahms was inspired by an alphorn melody he heard in the Rigi area of Switzerland when composing the great melody that opens the last movement of his First Symphony.
