The violin, sometimes known as a fiddle, is a wooden string instrument in the violin family. Most violins have a hollow wooden body. It is the smallest and highest-pitched instrument (soprano) in the family in regular use. Smaller violin-type instruments exist, including the violino piccolo and the pochette, but these are virtually unused. The violin typically has four strings, usually tuned in perfect fifths with notes G3, D4, A4, E5, and is most commonly played by drawing a bow across its strings. It can also be played by plucking the strings with the fingers (pizzicato) and, in specialized cases, by striking the strings with the wooden side of the bow.
