String techniques refer to various methods used in music to produce sound from stringed instruments, such as the violin, guitar, and cello. These techniques include bowing, plucking, and strumming, each creating distinct tones and effects. For example, bowing involves drawing a bow across the strings, while plucking, or pizzicato, involves using fingers to pull and release the strings. Additionally, string techniques can encompass advanced methods like harmonics, where players lightly touch the strings to produce higher pitches, and vibrato, which adds expression by oscillating the pitch. Mastery of these techniques enhances a musician's ability to convey emotion and complexity in their performances.
