Which of the following best describes percussion instruments?

Percussion instruments are defined by how their sound is produced: mainly by the instrument’s own body vibrating when it is struck, shaken, or scraped. The two core groups are idiophones, which produce sound from the material of the instrument itself (like bells or a xylophone), and membranophones, which use a stretched membrane that vibrates (like drums). In addition, some chordophones that are struck—rather than bowed or plucked—also fit percussion, since the action that creates the sound is striking. That combination—membranophones and idiophones, plus struck chordophones—best captures what percussion encompasses. The other descriptions focus on how the sound is produced in general (air vibration, strings, or electronic generation) and don’t align with the percussion family as commonly categorized.
