By the end of the 20th century the educational role of music has come into the spotlight, and in addition to the impact of music on the development of general skills, its social and emotional effects are also the subject of research. This paper undertakes to explore the literature about the connections between music education and social-emotional skill development. For the collection and analysis of information, online sources of peer-reviewed scientific journals in addition to the university library were used. The study also examined the relationship between social-emotional learning and the world-wide well-known Kodály Concept and the effect of Kodály's vision of music education as a forerunner of socio-emotional skills development. The relationship between social-emotional skills and music was explored by reviewing the international music-specific literature from music psychology, music education, music therapy, and music for health and wellbeing. In order to illuminate the problem and to develop a holistic approach, the 100 studies presented here summarize research findings made and presented in different countries around the world.
