The little gates that control the airflow through a brass instrument are called valves.

Valves are mechanical devices that can open or close pathways, and in the context of brass instruments, they govern the flow of air within the instrument. When a musician presses a valve, it changes the length of the tubing that the air must travel through, which alters the pitch of the note being played. This modification of airflow allows brass players to create a wide range of musical notes and dynamics.

There are typically three or four valves on a brass instrument, such as a trumpet or tuba, and they are essential for playing various scales and notes effectively. These valves enhance the versatility and expressiveness of brass instruments, making them a fundamental component in their design.
