Question

the piano is the weird instrument that can be considered both a _____________ and an _____________ (choose 2!).
select all correct options
aerophone
membranophone
idiophone
chordophone

Explanation:

Pianos produce sound when hammers strike steel strings (classifying them as chordophones, instruments where vibrating strings create sound). They are also classified as idiophones because the vibrating soundboard (a solid part of the instrument) amplifies the sound, which fits the idiophone category of sound produced by a vibrating solid material. Aerophones use air vibration, and membranophones use stretched membranes, which do not apply to pianos.

Answer:

idiophone, chordophone
