(b Medicina, nr Bologna, c1660; d after in or 1699). Italian composer. He came from a Jewish family, but he converted to Christianity and entered the Carmelite monastery in Bologna. According to the title-pages and dedications of his works, he was maestro di cappella of Ravenna Cathedral from 1691 to 1699. The statement (in EitnerQ) that he was maestro di cappella at Medicina in 1692 may stem from a misreading of the title-page of op.2. Vannini's extant music consists of sacred polyphonic works for voices and instruments; they reveal him as a composer of moderate significance and skill.
