What do you call an instrument that creates sound by vibrating air?

• A. Aerophone
• B. Membranophone
• C. Idiophone
• D. Vocal

Answer: (A)

When a sound is produced by making the air itself vibrate, the instrument falls into the aerophone category. This includes instruments where the air column is set into oscillation by the player's breath, lips, or a vibrating reed—like flutes, brass instruments, and woodwinds. That direct interaction with vibrating air is what defines an aerophone. Membranophones produce sound from a vibrating membrane, such as a drum skin; idiophones produce sound from the instrument’s own body vibrating (like a bell or xylophone). The term vocal refers to the human voice, not an instrument class, so it doesn’t fit the given description of an instrument generating sound by vibrating air. Hence, the best label for an instrument that creates sound by vibrating air is aerophone.
