In percussion classification, which additional subcategory is sometimes included besides membranophones and idiophones?

• A. Aerophones
• B. Struck chordophones
• C. Substituted idiophones
• D. Elektronophones

Answer: (B)

In percussion classification, an extra subcategory is used for instruments whose sound comes from vibrating strings but that are played by striking. These are called struck chordophones. They fit here because the instrument’s tone originates from string vibration, which makes it a chordophone, while the act of playing—striking with mallets or hammers—aligns with percussion technique. This combination sets them apart from membranophones (drums where sound comes from stretched membranes) and idiophones (solid bodies that vibrate to produce sound without strings). Aerophones would involve sound produced by vibrating air, not strings, so they belong in a wind-instrument category. Substituted idiophones isn’t a standard category, and elektronophones refer to electronic sound sources rather than a traditional percussion grouping.
