Giulia is taking piano lessons for an important concert, her debut with Ludwig Van Beethoven’s «Moonlight Sonata» no.14. Her days are punctuated by meticulous exercise, manic routine and a constant pressure, embodied and strengthened by her teacher and mentor, who encourages Giulia to give her best with constancy and dedication, to commit more and more, emphasizing her imperfections, staying faithful with his strict teaching method. Such a fight against the slightest flaw of execution shows on the one hand an extraordinary strength of mind of Giulia, motivated by her own attachment to music, and on the other hand reveals a fragility that leads her to feel bad and to hide, not to live fully. Because Giulia in her heart desires to sing, but she preys on the shyness of her fails to unlock. A path that passes from her discomfort thinking to be evaluated by the Master only “on the surface”, by the tiring psycho-emotional impact, to the need to bring out one’s voice as an authentic mirror of being. She succeeds in this enterprise thanks to that gruff and aggressive teacher, who however manages to read the desire hidden in her.
