The violin is a highly versatile, bowed string instrument known for its wide range and expressive capabilities. It has four strings, typically tuned to G, D, A, and E, and is played with a bow or by plucking the strings. The instrument's hollow wooden body amplifies its sound, producing a rich, resonant tone. The violin is integral to Western classical music, where it plays both solo and orchestral roles, and is also popular in folk, jazz, and contemporary music. In Indian classical music, the violin is adapted for sitting postures and tuned differently to suit ragas, making it central to Carnatic and Hindustani traditions.
