An associate of Giuseppe Verdi's, he also taught two internationally renowned Italian operatic tenors, Francesco Tamagno and Alessandro Bonci.
Fiorina (1851), another opera semiseria, was a success in Italy and beyond, and the commedia lirica Tutti in maschera (1856), his best-known work, was later taken up in Vienna and Paris.
At the Liceo, his pupils included the composer and orchestral musician Raffaello Squarise and the heroic tenor Francesco Tamagno, who later created the title role in Verdi's penultimate masterpiece, Otello.
He composed the Tuba mirum section of the Dies Irae, for solo baritone and chorus, but for various reasons the work was never performed in public during his lifetime.
