The buccin, or buccin à tête de serpent, is a visually distinctive trombone popularized in military bands in France between 1810 and 1845 which subsequently faded into obscurity. It should not be confused with another instrument also called "buccin", revived in France in 1791 and modeled after the ancient Roman buccina which could deliver only four distinct notes.

The trombone is a musical instrument in the brass family. As with all brass instruments, sound is produced when the player's vibrating lips cause the air column inside the instrument to vibrate. Nearly all trombones use a telescoping slide mechanism to alter the pitch instead of the valves used by other brass instruments. The valve trombone is an exception, using three valves similar to those on a trumpet, and the superbone has valves and a slide.
