Like his father, Valentino Fioravanti, he specialised in the opera buffa genre, but he also composed sacred music including two oratorios during his time as maestro di cappella of Lanciano Cathedral (1839–1843).
He made his debut as composer at the Teatro San Carlino in Naples in 1819 with the premiere of La Pulcinella molinaro, spaventato dalla fata Serafinetta, an opera buffa set to a libretto by Filippo Cammarano.
[1][2] The following year, he returned to Rome, sought advice from Donizetti, and completed his second opera, La contadina fortunata which had a successful premiere at the Teatro Valle in November 1820.
Disappointed in his hopes of receiving the chair in counterpoint at the Conservatory of San Pietro a Majella, Fioravanti's economic position became increasingly perilous.
A serious illness in 1872 forced him to give up the position, although the music school continued to pay his salary and provide food and lodging for the rest of his life.
Federico Polidoro, who visited Fioravanti in the last week of his life, wrote that he had remained lucid until the end and had said that the greatest joy of his last years was seeing his long-ago student Nicola D'Arienzo become the professor of counterpoint at San Pietro a Majella.
