This dissertation in Italian language, which roughly translates to "Ludic Score - a Linguistic Approach to Musical Paradigms in Videogames", explores the meaning embedded in game music. The thesis suggests a linguistic approach to the analysis of the musical components of the videogame, supporting the fundamental role of the latter in the semantic structure of the medium. The dissertation defines a musical morphology of video games through a number of case histories and the application of linguistics methods: a paradigmatic model of musical analysis, the Ludic Score, is proposed to represent the musical structure of the videogame and the semantic relations between its music cues.
