FIDELIO is and remains the work for active music education! Ten thematic chapters drawn from the experiences and worlds of children ensure the acquisition of all competencies. Musical fundamentals are playfully and consistently integrated into the children's activities. Cooperative learning and natural differentiation - even in music! Open tasks and impulses allow for individual learning paths. Diverse learning forms and varied methods open up music education and enhance the children's initiative! A new variety in all areas: a modern, attractive mix of songs, dances, and listening pieces offers a wide range of choices. New spoken pieces and appealing media hits create a strong sense of identification. New interdisciplinary songs and ideas connect the subject of music with language, art, local studies, religion, and mathematics.
