Symphony No. 3 in E-flat major, Opus 55 (also Italian Sinfonia Eroica, Heroic Symphony) is a structurally rigorous composition of great emotional depth.
Symphony No. 3 marked the beginning of the creative middle-period of the composer Ludwig van Beethoven.
Beethoven began composing the third symphony soon after Symphony No. 2 in D major, Opus 36; he completed the composition in early 1804, and the first public performance of Symphony No. 3 was on April 7, 1805 in Vienna.
