A journey with a young listener to the sound university. The main characters of this musical journey are seemingly unrelated everyday objects: crystal bowls, drinking glasses, tiles, blocks of sandpaper, bolts, and nails, groats, and papers. The concert introduces an exciting world of sound that can be created with unusual instruments. On the stage are featured the Estonian Composers' Ensemble (EHA) consisting of Helena Tulve, Tatjana Kozlova-Johannes, Ülo Krigul, and Maria Kõrvits and twenty children-sound masters, who bring to the listeners a musical work for sound objects with theatrical elements.Authors and performers of the music: Estonian Composers' Ensemble and children aged 10–13.Age: 6+
