Jasmine wants to play a song for Dudua's birthday party and Jambo wants to dress up for the occasion, but the music she plays and the clothes he wears don't go together; Jambo and Jasmine try different music and outfits to see if they match.

After staying up all night making music, Jambo wants to sleep; Dubidu and the Lalalas are playful and won't be quiet; Jasmine decides to tackle the problem and use the noises to make a lullaby that makes all Soundland sleepy.

Jasmine makes a song for the Major Festival in Soundland; everyone cries when she finishes playing it; Jasmine is frustrated as she wanted the song to be cheerful; Jambo makes the song much more cheerful by changing one note.

The Moon is sleeping; if they don't wake it up, the day won't come; Jambo solves the problem by climbing up the tallest buildings in Soundland; Jasmine tries to wake the Moon up on the ground, playing high musical scales with the Lalalas.

Jasmine and Jambo catch a bottle with a musical score inside that is difficult to play; both of them try playing it without much success; they create a symphony of grumbles and protests, which ends up fascinating the audience.

The Garden of Instruments is untidy and Jambo can't find his grandmother's violin; Jasmine finds it, but she accidentally breaks the strings; she replaces them with more unconventional ones: a cat hair, a shoelace, a guitar string and a washing line.
