The article is devoted to the scientific development of the problem related to the development of an artistic taste of the future teachers specialised in Musical Art. The purpose of the article is to theoretically and methodologically substantiate the development process of an artistic taste of the future teachers specialised in Musical Art in the process of teaching pop singing. The purpose is realised through the implementation of relevant tasks using the methods of theoretical research: analysis, synthesis, deduction, induction, generalisation and extrapolation. The article considers the category "artistic taste" as a person's ability developed by social practice to evaluate aesthetic phenomena, to distinguish beautiful things from ugly ones. The artistic taste of the future teachers of Musical Art is defined as an individual, socially conditioned system of evaluation of phenomena reflected in works of art, aimed at widening the worldview of an individual. The component structure of the artistic taste of the future teachers specialised in Musical Art consists of four components: personal-motivational, sensory-perceptual, intellectual-interpretive and reflexive-projective. Professional training of the future Music teachers is considered as a platform for the formation of their artistic taste. We find the specifics of training future professionals in pop singing particularly important in the context of the study. The pop variety of vocal music is recognised as the one that provides for effective pedagogical influence; in particular, it is aimed at forming the artistic taste of the younger generation, based on the needs, interests and perception level of most students. A set of scientific approaches is considered as a methodological basis for the formation of the future Music teachers’ artistic taste in the process of teaching them pop singing: axiological, student-centred and holistic approaches. The study also presents pedagogical principles, the implementation of which ensures the formation of the future Music teachers’ artistic taste in the process of teaching them pop singing.
