This project is part of Spoke 2 “Creativity and Intangible Heritage”, Work Package 1, of the PNRR Extended Partnership 5 Changes program (Cultural Heritage Active Innovation for Sustainable Society). It focuses on Milanese publishing of “ready-made” music in the early twentieth century. The research is based on the identification and cataloguing of collections of mood music for films, dance music for orchestras, intermezzi for theatres, café-concerts, grand hotels, and other occasions, which are the products of a specialized publishing tradition by Milanese publishers such as Ricordi, Carisch, and Sonzogno. The project aims to identify and catalogue musical documents not only for the purposes of a history of applied composition, but also as a broader contribution to the history of early twentieth-century musical culture. The main product of the research will be a database conceived as a tool for structuring, ordering, mapping, and relating different types of objects: texts, images, musical documents in notation, and audiovisual material. The database will serve as a reference tool for basic research and provide useful support for teaching and creative or applied research. It will integrate bibliographic information with innovative methods of interactive audiovisual presentation, thus facilitating the dissemination and transfer of results to students, scientific audiences, and the general public.
