How Brass Instruments Work. Brass instruments are any tube that can be played with the lips. They're not always brass, as instruments like the Aborigine digeridoo, and the conch shell, are made of wood, and shell, respectively. However, most modern brass instruments have a long, cone-shaped tube and flaring bell. Usually the tube is coiled in order to make it easier to hold. Often they have valves or other mechanisms to extend the range of notes that can be played with the instrument. Making Sound . Modern brass instruments produce sound through a metal mouthpiece. The mouthpiece is similar on most brass instruments, usually varying only in size. Sound is produced by placing the lips on the mouthpiece and blowing while vibrating the lips.
