The new "Musikus" is relevant to contemporary teaching and age-appropriate. The work approaches musical themes in an interdisciplinary manner and conveys them integratively, action-oriented, and especially through non-musical contexts. The structure follows the seasonal rhythm 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-mimic and scenic representation, as well as for dance and movement. Following the main part with thematic double pages, there is a 34-page appendix of songs. 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 such as audio CDs with listening examples, dance, and song accompaniments are also included.
