Two compact disc recordings (sold as a two-disc set) support the concepts introduced in Level 4. The disc for the Music Lesson Book includes the narration for the story, as well as two performances of each piece—an acoustic piano version and an orchestrated version. The disc for the Music Discovery Book contains all of the songs and the "Listen and Sing" examples in the book performed by a teacher and students. In addition, professional performances of all listening examples for music appreciation and movement activities are included.
