Abstract: The object of the study is the Theory of Interpretation in musical art. The subject of the study is the cognitive model of interpretation in musical art.  Particular attention is paid to the interpretation research of musical text from the standpoint of cognitive scientific paradigms, which implies knowledge of the laws and ways of evolution of musical culture, understanding of the functions, structure, content and language of musical art, analysis of the mechanisms of musical thinking. Expansion of the opportunities to learn about musical art is accompanied by a process of cognitive immersion into the nature of musical knowledge itself.  The methodological basis of the work is a cognitive approach that allows considering interpretation in musical art as a phenomenon connected with processes of musical thinking, consciousness, memory, and cognitive activity in general.  The novelty of the study is as follows:  the author developed and proposed a method of cognitive analysis of a musical text that allows covering the phenomenon under study as an artistic integrity in broad interrelations with the knowing subject, his/her intellect, experience, level of mental activity, as well as with the surrounding world. Main conclusions of the study: The cognitive model of interpretation in musical art is a methodological tool in the focus of which the facets (associated with assimilation of special knowledge, with methods of their mental organization, with formation of artistic ideas and their embodiment in acoustic, verbal and nonverbal forms) of musical conception of the cognitive process of the subject are manifested . Methodological foundations of the cognitive approach allow us tohighlight some new key points indicating the significant perspectives in understanding the semantic structure of interpretation in musical art in its multiple links with the knowing subject, his/her intellect, experience, and level of mental activity.
