It is about exploring the musicality of "special" books, especially beautiful and evocative, of exploiting their creative stimuli, to make them live within the performance. The Chorus reads, observes, comments on the books and composes songs and stage actions that are in close resonance with those books. Some of the authors involved (Mauro Bellei and Katsumi Komagata) meet and work with the children in the preparation of the performance. They will be present with them on stage to present, with their voice or their gestures, books to the public. The concert also sees the meeting between the violinist Silvia Tarozzi, co-director of the Choir, the composer Pascale Criton and the artist Fanette Mellier, who relate the composition for microtonal violin "Circle Process" with the book "Au soleil" : two works that proceed by gradual chromatic-sonorous transformations without solution of continuity or narration, entrusting the task of structuring the composition entirely to the color-sound.
