The following paper aims at describing the metaphorical conceptualization of musica in the cognitive approach. The linguistic corpus consists of texts of music theory and music history manuals and texts of interviews with music artists. The chosen methodology, cognitive semantics, allows to explain how the concept of musica is expressed by means of the metaphor of human being. The musica is recognized as a human organism which has its physicality (materiality of body) and psychology (immateriality of mind).
