String Instrument Brief Introduction

String instruments or stringed instruments are musical instruments that produce sound from vibrating strings, which may be made of vegetable fibre, metal, animal gut, silk, or artificial materials such as plastic or nylon. In nearly all stringed instruments the sound of the vibrating string is amplified by the use of a resonating chamber or soundboard. The vibrations are transmitted to the body of the instrument, which also vibrates, along with the air inside it.
