Music has been an important segment in life of every individual since ancient times. Its universal nature is emphasized by the American poet Henry Hadsworth Longfellow, who says that music is in fact the universal language of mankind. It is a well-known fact that music has a positive effect on a child's prenatal development and that a child reacts to music at the earliest stage of his life. Since the child's environment plays an important role in the development of a child's musical skills, it is necessary to start developing the child's musical skills as early as possible. In addition to parents and educators, primary education teachers have a key role to play in developing musical skills. Therefore, the framework of this paper is the role of primary education teachers in teaching music and developing the musical skills of first grade students. This paper discusses music as art and the important role of the subject Musical culture in the educational process. Furthermore, it is stated that the teacher of primary education should possess competencies focused on singing, playing, listening to music, musical creativity and musical games. The primary education teacher's role is to introduce students to musical culture and to encourage and influence the development of students' musical skills. In order for the musical culture to be dynamic and creative, it is necessary to carefully select methodological procedures. Methodical procedures in the lower grades of elementary school in the music culture setting are procedures for singing in class, procedures for playing instruments in class, procedures for listening to and getting to know music in class, and procedures for performing musical games and dancing in class. Using different methodological procedures in the musical culture class in the lower grades of primary school contributes to a better acquisition of musical content. This paper seeks to show the importance of the role which teachers in primary education have during music teaching and development of musical skills of first grade students and a experimental research was conducted in the first grade of a primary school that puts the role of primary education teachers at the center of musical skills development.
