In the summer of 1812, Beethoven composed the Symphony no. 8 in F Major, op. 83. On its surface, the symphony seems to be in the Classical style, but it is filled with modern twists and turns. He was depressed over the loss of a relationship and his worsening hearing. But in 1813, he wrote a piece of music commemorating the defeat by Wellington of one of Napoleon's armies. When it premiered in December of 1813, it garnered Beethoven a new level of popularity.
