Although Sibelius’s Fifth Symphony seemingly has three movements, the first movement contains an allegro and a scherzo, providing the feeling of four movements for the symphony. In its entirety, the symphony can be heard as a “struggle” leading to the “victory” heard in the beautiful “Swan Theme” at 1:24 in the video below. The theme was said to be inspired by the swan calls Sibelius heard after watching sixteen swans taking flight at once.
Note the unusual ending for the symphony.
