String instruments are a family of musical instruments that produce sound through the vibration of strings. The strings are stretched across a resonating body, and the sound is amplified by the instrument’s hollow body or other resonating mechanisms. Players produce sound by plucking, bowing, or striking the strings, and the pitch is controlled by the length, tension, and thickness of the strings.

• Bowed: Violin, Viola, Cello, Double Bass.
• Plucked: Guitar, Harp, Mandolin, Ukulele, Sitar.
• Struck: Piano, Dulcimer.
