How do aerophones make sound?

• A. The membrane vibrates to produce sound waves
• B. A vibrating column of air produces sound waves
• C. The strings vibrate
• D. The frame vibrates

Answer: (B)

Aerophones produce sound by vibrating air. When you play one, your breath excites a column of air inside the instrument to oscillate, and this vibrating air creates the sound waves we hear. The length and shape of the air column, along with how the air is set into motion (blown across an edge, buzzed by lips, or set by a reed), determine the pitch and timbre. This is different from other families, where the sound comes from vibrating membranes, strings, or the instrument’s frame rather than the air column itself.
