What instrument makes sound this way?

A guitar makes music when a musician plucks or strums its strings, causing them to vibrate rapidly. Those vibrations travel through the guitar's hollow wooden body, which amplifies the sound so it's loud enough to hear clearly, with different string thicknesses and lengths producing different musical notes.

A drum makes sound by being struck, causing a stretched surface to vibrate, rather than from strings, and a trumpet produces sound when a player buzzes their lips into a mouthpiece, vibrating air inside a metal tube — both very different methods from plucking strings.

Guitars come in many forms, including acoustic guitars that rely on their wooden body alone and electric guitars that use magnetic pickups to turn string vibrations into an electrical signal sent to an amplifier.
