The symphony and the concerto are musical forms with a long history. The former is the fundamental means of expression for a symphony orchestra, making use of all its capabilities. The concerto, on the other hand, allows a solo instrument to be highlighted, which dialogues with the orchestra. In Harold en Italie, Hector Berlioz created a hybrid model, in which the protagonism is divided and the soloist can also express themselves through silences. It was the famous Paganini who commissioned the work, but he was disappointed to see that the score did not allow him to stand out throughout and refused to play it. Later, upon hearing it, he knelt before Berlioz, moved by the genius of the composition. This concert with commentary also reveals the poetic narrative behind the music: the melancholic wanderings of a young man disillusioned by the futility of life.
