The principle of student-centered education, which has become increasingly important in recent years, is called the "principle of student suitability". In the education process, which will be determined according to the student, the teacher's inferences about how and in what way the student acquired and comprehended the information may have positive results in the learning-teaching processes. Especially in instrument training lessons, which is an important sub-dimension of music education, one-to-one communication between the teacher and the student makes the principle of suitability for the student inevitable. In this study based on the scanning model, the document analysis method was used. In the study, firstly, what the MBTI (Myers-Briggs Type Indicator) inventory is explained. Then, different studies aiming to determine the personality types of students and teachers in the field of music education are included. Research on the subject was grouped under five themes (author of the research, year of the research, type of research, name of the research, place where the research was conducted) and analyzed by content analysis and shown in the table. It was found that the research conducted was mostly doctoral and master's theses. Additionally, when the relevant research results are examined; it is seen that in an education process planned according to the MBTI inventory, success in instrument lessons increases, students with extrovert (E) preference tend to focus on voice training, and introvert (I) students focus on instrument performance.
