Il Cannone Guarnerius of 1743 is a violin created by the Italian luthier Giuseppe Antonio Guarneri of Cremona (1698–1744). Il Cannone is also known by the variants Il Cannone del Gesù, the Cannon, often appended with Guarneri del Gesù, the Guarneri trademark. The violin received its name from a former owner, the Italian violin virtuoso Niccolò Paganini (1782–1840), because of its power and resonance. So associated is Paganini with Il Cannone that it is common for the violin to be referenced as Il Cannone, ex Paganini. Paganini lost a valuable Antonio Amati violin as a result of his penchant for voracious gambling. He was given a neglected Guarneri violin, a gift from an amateur violinist and businessman. Paganini played on this instrument for the rest of his life, fondly calling it “my cannon violin,” referring to the explosive sound that he was able to make it produce. He bequeathed it to the city of Genoa, Italy upon his death, and it is now considered a national treasure. When in need of repair, Il Cannone would be sent to the workshop of Jean Baptiste Vuillaume (1798–1875) in Paris, the greatest luthier of his day. Not only did Vuillaume repair the Guarnerius, but he also made an exact replica. The copy was so exact, that not even Paganini could distinguish one from the other. It was not until Paganini noticed subtle differences in tone that he could identify the original. Paganini presented the copy to his only student, Camillo Sivori, who would later bequeath the instrument to the Municipality of Genoa, where it now is exhibited with the original Il Cannone. Il Cannone is exhibited alongside other Paganini memorabilia within the Paganini room of the Palazzo Doria-Tursi, the Genoa town hall. The original violin is maintained in playable condition, and is taken out and played monthly by its curator. The Cannone was played each year by the winner of the Premio Paganini contest for young violinists, which sees the Italian city attracting the cream of the crop of young violin performers (since 2002 the contest has been held every two years). On occasion, Il Cannone is loaned to musicians for performance. In 1996, violinist Eduard Schmieder was invited and gave a recital on Il Cannone in Genoa at the Palazzo Ducale for the audience of 2000 (with pianist Valentina Lisitsa); on this rare occasion, a posthumous International Peace Prize ceremony was given
