Details of his life for the period in which he was in Rome are equally uncertain. It is known that he was active as a composer of madrigals from approximately 1540 to 1546, during which time he almost certainly knew the renowned madrigal composer Jacques Arcadelt, then singing in the Sistine Chapel choir, since they were both members of an "academy of friends" gathered around a Florentine banker who was resident in Rome (Arcadelt's membership in the group is uncertain, but considered probable). One of Arcadelt's Venetian publications, his "Il quinto libro di madrigali" (Fifth Book of Madrigals) (1544), includes six pieces by Naich, further indicating a connection between the two.
