Alphorn
Alphorn (Alphorn) or Alpenhorn (Alpenhorn) is a type of brass instrument and plays with a cup-like mouthpiece attached to a wooden conical tube. It is used by residents of the mountains such as Switzerland. Tubes are made by hollowing out natural trees (many spruce, possibly pine) (now many carbon fiber products are also available). It is a conical tube, most of the tube is straight, but in the well-known example the tip bends and opens like a trumpet. In the past I used a tree bent to fit the shape of the instrument, but now it is divided and made. Make a mouthpiece with hard wood, and attach it and it is complete. Alphorn is one of the open wind instruments. Since there is neither a valve mechanism nor a slide mechanism nor a sound hole, only a natural overtone string can be outputted. Since a tube thinner than the length is used, it is easy to produce a harmonic overtone. Alpohorn (currently in Victoria \u0026 amp; Albert Museum) made in Mount Rigi in Schwyz State is about 2.
