Brass instruments are a type of instrument described as what?

• A. Membranophones
• B. Idiophones
• C. Chordophones
• D. Aerophones made of metal

Answer: (D)

Brass instruments are defined by how they produce sound: the air inside the instrument vibrates to create the pitch. When the musician buzzes the lips into the mouthpiece, that buzzing sets up a vibrating air column in the metal tube, and the instrument’s shape and valves shape the final pitch. That mechanism—sound produced by vibrating air—puts brass instruments in the aerophone family. The metal construction is typical for brass instruments, but the material isn’t what defines the category; it’s the way the sound is produced. By contrast, membranophones rely on a vibrating membrane, idiophones on the instrument’s own body without strings or membranes, and chordophones on vibrating strings.
