Answer
The answer is the Pre-Aida Verdi roles. Bel canto is an Italian operatic singing style that emphasizes technical skill, vocal agility, and a beautiful tone. Luciano Pavarotti, known as one of the greatest tenors of all time, was a prominent exponent of this style. The Pre-Aida Verdi roles refer to the operas composed by Giuseppe Verdi before his opera "Aida" (1871).
