The term 'Brass Section' refers to a group of instruments typically found in a symphonic orchestra. This group includes tubas, HORNS, and ZINC. Tubas are large, low-pitched brass instruments that produce a deep, resonant sound. HORNS are also brass instruments, but they are smaller and produce a higher-pitched sound. ZINC is a metal alloy made up of copper and tin, which is used to make brass instruments. Together, these three instruments create a unique sound that is often used in classical music.
