Which category includes brass and wind instruments?

• A. Chordophones
• B. Membranophones
• C. Idiophones
• D. Aerophones

Answer: (D)

Sound is produced by vibrating air, so instruments that create sound this way are grouped as aerophones. Brass players set the air column in vibration by buzzing their lips into a mouthpiece, while wind instruments (like woodwinds) start the vibration with reeds or edge tones. The other families produce sound differently: chordophones rely on vibrating strings, membranophones on vibrating membranes, and idiophones on the instrument’s own body vibrating. So brass and wind instruments belong to aerophones.
