The new "Musikus" is relevant to contemporary and age-appropriate teaching, focusing on subject matter and themes. The work approaches musical topics in an interdisciplinary manner and conveys them integratively, action-oriented, and primarily through non-musical contexts. The structure follows the seasonally influenced course of a school year and can serve as a basis for annual planning. The new "Musikus" provides impulses for singing and making music, for improvisation and listening, for gestural-mimetic and scenic representation, as well as for dance and movement. Following the main part with thematic double pages, there is a 34-page song appendix. A systematic summary of voice, dance, music theory, and instruments concludes the work. "Musikus" and "Musika" accompany the children throughout the book and frequently interject with comments. Accompanying materials include audio CDs with listening examples, dance, and song accompaniments.
