The aim of this paper is to integrate music and its therapeutic possibilities in an educational institution for early and preschool education, since these two areas can contribute to the development of preschool children. Therefore, the paper presents the benefits of music for the development of a child of early and preschool age, and then defines the area, goals, purpose, principles, and methods of music therapy. The paper presents the values of music therapy and its importance in the context of an educational institution for early and preschool education through examples of Croatian and foreign practice. Music therapy is predominantly used in working with children with developmental difficulties, but the advantages of its principles and methods open wide possibilities for implementation in educational work with inclusive groups and groups of children with typical development, which are confirmed by examples of analysed practices, collected in professional and scientific literature. A comparative presentation of the two mentioned areas confirms the justification for applying some elements of music therapy in the regular education system because it positively affects the social environment and the overall development of individuals in the group.
