II. Andante molto mosso
This movement, entitled by Beethoven "By the brook," is held to be one of Beethoven's most beautiful and serene compositions. At the opening the strings play a motif that clearly imitates flowing water.
III. Allegro
This is the scherzo movement of the symphony, which depicts the country folk dancing and reveling.
IV. Allegro
depicts a violent thunderstorm with painstaking realism, starting with just a few drops of rain and building to a great climax.
