Alpenhorn
ALPENHORN, ALPHORN, a musical instrument, consisting of a
natural wooden horn of conical bore, having a cup-shaped mouthpiece,
used by mountaineers in Switzerland and elsewhere. The tube is made of
thin strips of birch wood soaked in water until they have become quite
pliable; they are then wound into a tube of conical form from 4 to 8 ft.
long, and neatly covered with bark. A cup-shaped mouthpiece carved out
of a block of hard wood is added and the instrument is complete. The
alpenhorn has no lateral openings and therefore gives the pure natural
harmonic series of the open pipe. The harmonics are the more readily
obtained by reason of the small diameter of the bore in relation to the
length. An alpenhorn made at Rigi-Kulm, Schwytz, and now in the South
Kensington Museum, measures 8 ft. in length and has a straight tube.
The well-known Ranz des Paches is the traditional melody of the
alpenhorn, which has been immortalized by Beethoven in the finale of the
Pastoral Symphony, where the music is generally rendered by a cor
aniglais. Rossini has introduced the melody into his opera William
Tell. Wagner, in the third act of Tristan and Isolde, was not entirely
satisfied with the tone quality of the cor anglais for
representing the natural pipe of the peasant.
Having in his mind the timbre of the alpenhorn, he had a wooden horn
made for him with one valve only and a small pear-shaped bell, which is
used at Bayreuth. The Swiss alpenhorn varies in shape according to the
locality, being curved near the bell in the Bernese Oberland. Michael
Praetorius mentions the alpenhorn under the name of holzerni trummet in
Syniagma Musicum (Wittenberg, 1615--1619).
