Biographical information on Fiorenza's schooling and early life is very scarce; he must have been born in the city of
Naples somewhere in the very beginning of the 18th century. Nevertheless, we can be sure that he received his training at the conservatory of S. Maria del Loreto in his hometown under
Giancarlo Cailò and
Francesco Barbella. The first verifiable date in Fiorenza's career is 1726, the year in which his
sinfonia in A minor for flute, two violins and basso continuo was published. From 1734 to 1740 Fiorenza played, maybe as a violinist, in the
Cappella Reale and with the orchestra of the
Teatro S. Bartolomeo. More information is available about Fiorenza's later years. An account of his election to the post of teacher for violin, cello and double bass at the Naples conservatory of S. Maria del Loreto on 22 May 1743 indicates that he succeeded
Nicola Vitolo (who in his turn was the successor of Fiorenza's former teacher
Barbella). From 1750 onwards, however, Fiorenza was confronted with a series of troubles at the conservatory. Not only did he engage in a violent conflict with one of his colleagues, the oboist
Cherubino Corena, he also seems to have had several altercations with his students. As a result of this, Fiorenza was dismissed from his post in 1763. Alongside his teaching activities at the conservatory of S. Maria del Loreto, Fiorenza seems to have remained active as a violinist in the
Cappella Reale, in 1754 taking over the leader's position from
Domenico de Matteis, who had died in that same year. On Fiorenza's activities between his dismissal in 1763 and his death on 13 April 1764, we lack all information. ==Works==
