Which instrument is considered an idiophone?

• A. Timpani
• B. Snare Drum
• C. Bass Drum
• D. Marimba

Answer: (D)

Idiophones produce sound from the vibration of the instrument’s own solid material when it’s struck, plucked, or rubbed. The marimba fits this idea because its wooden bars are the primary vibrating elements; when you strike a bar, the bar itself vibrates to produce a pitched tone, with the resonance of the frame and attached resonators helping amplify the sound. In contrast, the timpani, snare drum, and bass drum produce sound mainly through membranes (drumheads) that vibrate when struck, so they’re membranophones rather than idiophones.
