The violin is a wooden string instrument. The violin typically has four strings tuned in perfect fifths, and is most commonly played by drawing a bow across its strings, though it can also be played by plucking the strings with the fingers. Violins are important instruments in a wide variety of musical genres. They are most prominent in the Western classical tradition and in many varieties of folk music. They are also frequently used in genres of folk including country music and bluegrass music and in jazz. Electric violins are used in some forms of rock music; further, the violin has come to be played in many non-Western music cultures, including Indian music and Iranian music. The violin is sometimes informally called a fiddle, particularly in Irish traditional music and bluegrass, but this nickname is also used regardless of the type of music played on it.
The violin was first known in 16th-century Italy, with some further modifications occurring in the 18th and 19th centuries. In Europe it served as the basis for stringed instruments used in western classical music, the viola and the violin. Violinists and collectors particularly prize the instruments made by the Stradivari, Guarneri and Amati families from the 16th to the 18th century in Brescia and Cremona and by Jacob Stainer in Austria. Baluswami Dikshitar, brother of renowned Karnatic Composer Muthuswami Dikshitar, learned the instrument from the military bandmaster in Madras and adapted his playing style to suit Karnatic Music.
