Italo Gardoni (12 March 1821 – 26 March 1882) was a leading operatic tenore di grazia singer from Italy who enjoyed a major international career during the middle decades of the 19th century. Along with Giovanni Mario, Gaetano Fraschini, Enrico Tamberlik and Antonio Giuglini, he was one of the most celebrated Italian tenors of his era.
His voice was not large but it was exceptionally pure toned and sweet, lacking any disruptive vibrato. He sang legato passages with impressive smoothness but he could also dispatch florid music with flair and considerable agility.
Born in Parma, Gardoni studied with Antonio De Cesari (1797–1853). He made his debut as Roberto Devereux (Donizetti) in Viadana in 1840, and over the following 7 years made his career in France, Italy and Germany. In Paris in December 1844 he was Bothwell in the Paris première of Louis Niedermeyer's opera Marie Stuart at the Théâtre de l'Académie Royale de Musique opposite the soprano Rosine Stoltz, and was with her again there for the premiere of Michael Balfe's L'étoile de Seville in the following year. Gardoni knew and worked with Balfe, who composed items particularly for him. The limpidity and clarity of his voice, and his ravishing upper notes (no less than his youth, charm and elegance) were greatly admired in Paris: and if he was not ready for all the roles from the repertoires of Adolphe Nourrit and Gilbert Duprez, still (they thought) some Meyerbeer would have suited him well, not least Raoul in Les Huguenots. Gardoni continued to sing in Paris throughout his career.
