Cipriano de Rore was closely associated with Adrian Willaert in Venice, and multiple sources suggest that he may have studied under Willaert during his early years in Italy. Although no definitive documentation survives to prove formal instruction, dedicatory material in Rore’s Venetian publications refers to him as a disciple or follower of Willaert, and stylistic evidence in his early madrigals shows clear indebtedness to Willaert and his circle. This makes an early period of study or mentorship in Venice before 1542 a reasonable and widely accepted supposition.
Some biographical sources go further, explicitly identifying Rore as a pupil of Willaert and stating that he sang in the chapel of St. Mark’s under him, while others treat the claim as probable but unconfirmed. Regardless of the documentary gaps, Rore’s later career reinforces the connection: in 1563, after Willaert’s death, Rore succeeded him as maestro di cappella at St. Mark’s, demonstrating the stature of their relationship and Rore’s position within Willaert’s artistic lineage.
