The Messiah - Salabue Stradivarius of 1716 is a violin made by the Italian luthier Antonio Stradivari of Cremona. It is considered to be the only Stradivarius in existence in as "new" state. The neck has been lengthened and at minimum the bass bar, bridge, tailpiece, and pegs have been replaced. It is in the collection of the Ashmolean Museum in Oxford, England.

The violin, colloquially known as a fiddle, is a wooden chordophone, and is the smallest, and thus highest-pitched instrument (soprano) in regular use in the violin family. Smaller violin-type instruments exist, including the violino piccolo and the pochette, but these are virtually unused. Most violins have a hollow wooden body, and commonly have four strings, usually tuned in perfect fifths with notes G3, D4, A4, E5, and are most commonly played by drawing a bow across the strings. The violin 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.
