The alphorn, alpenhorn, or alpine horn is a labrophone, consisting of a straight several-meter-long wooden natural horn of conical bore, with a wooden cup-shaped mouthpiece. Traditionally the alphorn was made of one single piece, or two parts at most, of the wood of a red pine tree. Sometimes the trees would bend from the weight of snow in winter, and this caused them to have the larger and bent mouthpiece at their ends.[1] Modern alphorns are sometimes made from three distinct parts that can be attached together: this is to make them easier to transport by car, or even to carry them by hand, and today they are more frequently made from the wood of a spruce tree or fir tree.[1] The alphorn is used by mountain dwellers in the Swiss Alps. Similar wooden horns were used for communication in most mountainous regions of Europe, from the Alps to the Carpathians.[citation needed] Alphorns are today used as musical instruments.
