The Saxhorn is a family of brass instruments invented by Adolphe Sax in the 1840s. It is characterized by its conical shape and mellow tone, making it popular in military and brass bands. The family includes various sizes, such as the soprano, alto, tenor, baritone, and bass saxhorn, each producing different pitches. Saxhorns are played using a mouthpiece and valves, allowing musicians to change notes easily. They are often used in ensemble settings, contributing to rich harmonies and melodies. The instrument's unique sound and versatility have made it a staple in both classical and contemporary music.
