Educational institutions represent one of the main forms of a child's life outside the family, and as such they should give equal importance to all areas of the child's development, because this is precisely the main feature of the integrated preschool curriculum. Any activity that promotes the development of one dimension also affects other dimensions of children's development. This final paper talks about the curriculum of work and preschool education, its historical development and the modern integrated curriculum that takes place in today's early and preschool education institutions. Furthermore, the paper deals with the impact of music on the overall development of a child. As an active being and the subject of his own development, the child shows interest in music and musical elements in his own way already in the first days of life.
