by Symphony No. 3 in E-flat major, Opus 55 (also Italian Sinfonia Eroica, Heroic Symphony) is a structurally rigorous composition of great emotional depth, which marked the beginning of the creative middle-period of the composer Ludwig van Beethoven.
The work is a milestone work of classical-style composition; it is twice as long as the symphonies of Joseph Haydn and Wolfgang Amadeus Mozart – the first movement is almost as long as a typical Classical symphony (with repetition of the exposition). Thematically, it covers more emotional ground than had Beethoven’s earlier symphonies, and thus marks the beginning of the Romantic period in classical music.
The second movement especially displays a great emotional range, from the misery of the funeral march theme, to the relative solace of happier, major-key episodes. The finale displays a similar emotional range, and is given a thematic importance then unheard of. In earlier symphonies, the finale was a quick and breezy conclusion; here, the finale is a lengthy set of variations and fugue on a theme from Beethoven’s music for the ballet The Creatures of Prometheus (1801).
Compositionally, the opening theme of Sinfonia Eroica resembles that of the overture to the comic opera Bastien und Bastienne (1768), composed by twelve-year-old W. A. Mozart. It was unlikely that Beethoven knew of that unpublished composition. A possible explanation is that Mozart and Beethoven each coincidentally heard and learned the theme from elsewhere.
