Plucked string instruments are musical instruments that produce sound by plucking or strumming their strings. Common examples include the guitar, banjo, and harp. These instruments can be made from various materials, such as wood or metal, and they come in different shapes and sizes, affecting their sound quality and volume. The strings of plucked instruments can be made from materials like nylon, steel, or gut. When a string is plucked, it vibrates, creating sound waves that resonate within the instrument's body. This mechanism allows musicians to create a wide range of tones and dynamics, making plucked string instruments versatile in many musical genres.
