Plucked instruments are musical instruments that produce sound by plucking or strumming strings. Common examples include the guitar, harp, and banjo. These instruments can vary in size, shape, and number of strings, and they are often used in various music genres, from classical to folk. The sound of plucked instruments is created when the strings vibrate after being plucked. The pitch of the sound depends on the string's length, thickness, and tension. Musicians can use their fingers or a plectrum to pluck the strings, allowing for a wide range of expressive techniques and styles.
