Subsequently, he appeared at La Scala in Milan (singing in all three of the Mozart/Da Ponte operas under conductor Riccardo Muti), and also in such cities as Turin, Verona, Bologna, Florence, and Naples, as well as major opera houses in Switzerland, France, Austria, Germany, England, Spain, Israel, and North and South America.
At the beginning of his career Corbelli sang lyric baritone roles, but his natural talent for comedy caused him eventually to be typecast in comic parts.
At the Royal Opera House, as of March 2012, Corbelli had taken part in 87 performances since his debut in 1988 (as Taddeo in L'Italiana in Algeri).
[2] Although primarily associated with Italian-language comic roles, Corbelli's résumé shows his wide-ranging interests and versatility, including French and German roles (Sulpice in Donizetti's La fille du regiment, Papageno in Mozart's Die Zauberflöte), Baroque opera (Seneca in Monteverdi’s L'incoronazione di Poppea) and a twentieth-century English-language opera (Nick Shadow in Stravinsky’s The Rake's Progress).
On 26 November 2007, while in London rehearsing for La Cenerentola, Corbelli stepped in at the last minute for a production of L'elisir d'amore at the Royal Opera House, singing the role of Belcore for the second half of the opera from the side of the stage while Ludovic Tézier, who had sung the first half with a throat infection, acted the role.
