The alphorn is a traditional wooden musical instrument originating from the Alpine regions of Switzerland and Germany. It is typically made from a single piece of wood and can be up to 4 meters long. The instrument produces a deep, resonant sound and is often used in folk music and celebrations. Alphorns are played by blowing into a mouthpiece, similar to a brass instrument. They have no valves or keys, allowing musicians to create a range of natural harmonics. The alphorn is not only a musical instrument but also a symbol of Alpine culture and heritage.
