What are idiophones?

What are idiophones?

• A. Instruments where the frame vibrates to make noise
• B. Instruments with membranes stretched across frames
• C. Instruments with strings
• D. Instruments that produce sound by air columns

Answer: (A)

Idiophones produce sound from the vibration of their own material. When you strike, shake, or rub the instrument, the body itself vibrates and creates the tone, with no separate membrane, string, or air column involved. That’s why common idiophones include things like xylophones, bells, triangles, and wooden blocks—their material alone vibrates to produce sound. By contrast, membranophones rely on a stretched membrane to vibrate, chordophones on vibrating strings, and aerophones on vibrating air in a tube or column. So the description of instruments where the frame itself vibrates to make noise matches idiophones precisely.
