Biography of Julian Gayarre (1844-1890), one of the best tenors of all times. At 19, a professor at the Conservatory of Music in Madrid heard him singing for the first time and offered him a scholarship to continue his studies. His artistic life runs between continued success, becoming the world's greatest tenor. But in 1890, while singing at the Teatro Real in Madrid, a failure in his voice is like a cruel reminder of what would happen a few days later: his death at a young age. The doctors gave a diagnosis, but his friends know that Julian Gayarre died because he could not sing anymore.
