(b Tolentino, 15 March 1790; d Pesaro, 5 or 6 Aug. 1848). Italian composer. He studied with Paisiello in Naples and, after trying his hand at writing operas, worked as a singing teacher there from 1815. Vaccai was more successful with later operas, two of which (Zadig ed Astartea and Giulietta e Romeo) were staged in 1825. In 1830 he went to Paris, where he again taught singing, and in the same year moved on to London for three years before returning to Italy. He was appointed professor of composition at the Milan Conservatory in 1838. Vaccai wrote a total of 17 operas, as well as church music, cantatas, songs, and four ballets, but he is best known for his singing tutor, the Metodo pratico di canto italiano per camera (London, 1832). His singing exercises are still in the repertory.
