The current article is an attempt to reveal the theoretical and practical foundations of the formation of individual-author identity of future teachers of music. In addition, to explore the basic vectors and factors of the concept of “I” in the paradigm of Self-Identity + Musician & Creativity Identity. The development and realization of experimental model of training of students for the purpose of individual-authorial identity formation became a tool of the aim realization. Research methods: formative experiment, online questionnaire using Google Forms, self-reflection survey with combined type questions and essays, statistical generalizations and complex data analysis, generalizations. Individual-authorial identity is interpreted within the experimental model of training as a set of complex connections between the individual “I” of the student and music as an art. In addition to important qualitative data obtained during the final stage of the experiment, it was also found that the average level of academic success in the experimental group was 17.8%–21.6% higher than the level of the parallel group, which worked on the usual educational model. 35.2% of respondents successfully work as a music teacher in educational institutions of different levels (against the average of 8.5-20.9%). Individual-author identity affects the effectiveness of learning and contributes to the formation of professional orientation. It focuses on a creative approach to teaching music and conscious development of creative abilities. The following research should focus on further testing of the proposed training model.
