A crucial figure in Western cultured music, Ludwig Van Beethoven is considered one of the greatest and most influential composers of all time. Despite the deafness that struck him prematurely even before he was thirty, he continued to compose, transmitting emotions, personal experiences and feelings with each of his works, leaving a musical production full of expressive strength and the ability to arouse emotions. Appreciated all over the world, two pieces of his classical / symphonic literature were performed: symphonies n.1 and n.2. Performed by the Orchestra of the University of the Sierra, they aroused a resounding ovation of acclaim and applause.
