Professor Slim deals here with the several roles that music can play in the artworks of the Renaissance, looking in particular at Italian painting of the 16th century. For understandable reasons, art historians sometimes neglect the role of music and, especially, that of musical notation when studying works of art. These studies not only identify musical compositions, wholly or partially inscribed in paintings - and tapestries, ceramics, prints as well - but also seek reasons why these particular musical compositions were included and analyse their relevance to the scene depicted. Furthermore, as many of these studies show, identifying a musical composition, especially if it has a text, leads to the formation of ideas about iconographical functions and thus augments interpretations of the visual art.
