Born into a
Florentine noble family on 17 July 1561, he was the son of Giovanni Corsi (1519–1571) and Alessandra Della Gherardesca (d. 1615). His father was an important merchant who expanded the family activities in Palermo and was also in charge of Cardinal
Ferdinando I de' Medici, Grand Duke of Tuscany. In 1569, Giovanni provided important services to the Cardinal but died early in 1571, leaving Jacopo, who was only 10 years old, to be raised by his uncle Antonio with a great inheritance of 90,000
ducats. Jacopo and his brothers Bardo and Giulio had good investments in mercantile education, which allowed them to continue managing the legacy left by their father. The private tutor of Jacopo and his brothers was Ser Francesco Olmi, who in time became the family's fullest confidant. They also had classes with the experienced musician, the madrigalist
Luca Bati, being the first Florentine musician to be paid for fixed tutoring (3 ducats monthly for each child). Bati taught Jacopo and his brothers to sing, play the piano and music theory. He first married Settimia Bandini in
Rome in 1591, the daughter of the prominent banker Pierantonio Bandini, who was a friend of his late father Giovanni. He had a daughter with her, Giulia Corsi, in 1591. He was widowed by his first wife the following year, in 1592; Giulia was only a year old at the time. and sponsoring young musicians and their shows, spreading music and art throughout Florence. The hereditary title of Maquis of Caiazzo was granted to his brother Bardo Corsi in 1617, just fifteen years after his death, and for this reason, he was the last deceased member of his line not to have received it, passing it directly to his son Giovanni years later. ==References==
