Agostino Diruta, born around 1590 in Perugia, was both the nephew and the student of Girolamo Diruta. Multiple sources note that Agostino received his musical training directly under Girolamo, who was an established organist, theorist, and composer of the late Renaissance. Girolamo is explicitly described as Agostino’s teacher, indicating a formal teacher‑student relationship within the family.
The two men were also related by blood: Girolamo Diruta, born in Deruta in the mid‑16th century, was Agostino’s uncle. This familial connection is confirmed across the biographical accounts, which describe Agostino as Girolamo’s nephew as well as his pupil, linking them through both kinship and professional musical lineage.
