The piano is typically categorized as which type of instrument?

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

Answer: (A)

When we classify instruments, the key idea is what part of the instrument vibrates to produce the sound. A chordophone is any instrument whose sound comes from vibrating strings. The piano fits this because pressing a key causes hammers to strike strings, making those strings vibrate and generate pitches. The body and soundboard amplify that vibration, but the vibrating element is the string itself. Aerophones create sound from vibrating air, membranophones from a stretched membrane, and idiophones from the instrument’s own solid material vibrating without strings. So the piano is categorized as a chordophone.
