Sonora's tale is full of art, being the main one: music. Each phase of the narrative is marked by a song that expresses, concentrates and guides the story to its summits. In the prelude, Escuriluz is the sung poetry that echoes as a musical background to set the plot. The smaller arrangement reproduced with the weight of the notes played by a melancholic piano, accompanied by a voice that seems to cry out for every word that sings, would inevitably produce: The Song of Death.
