The French horn is a brass instrument known for its rich, warm sound. It has a coiled shape and a wide bell that helps produce its unique tone. Musicians play the French horn by buzzing their lips into a mouthpiece and using their fingers to press valves, which change the pitch of the notes. Often found in orchestras and bands, the French horn plays both melody and harmony. It is closely associated with classical music and is featured in compositions by famous composers like Wolfgang Amadeus Mozart and Richard Strauss. Its versatility makes it a favorite among many musicians.
