If you have seen a Ricola commercial, you are familiar with the alphorn (aka the alpenhorn). It is a giant horn made of wood. In the 18th century, it was used by shepherds to communicate across mountains. It is still popular there. Like yodeling and the accordion, it is a symbol of traditional Swiss music. In fact, it is the Swiss national instrument.
If you are interested in playing one, you’d better have a good set of lungs. It requires steady power to produce a sound. Not surprisingly, it is loud. Really, really loud.
Here is a link to a WSJ article on new, young stars of alphorn music. They are creating a stir by getting creative with the alphorn. Traditionalists disapprove.
