String instrument
String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when the performer plays or sounds the strings in some manner.

In some keyboard instruments, such as the harpsichord, the musician presses a key that plucks the string.

Strings are lengths of a flexible material that a musical instrument holds under tension so that they can vibrate freely, but controllably.
