Symphony no. 3 "Eroica", Symphony no. 4

Symphony No. 3 in E-flat major, Op. 55, "Eroica", and Symphony No. 4 in B-flat major, Op. 60, are symphonies by Ludwig van Beethoven, completed in 1804 and 1806 respectively. They are works that show Beethoven's shift from his early classical roots toward larger forms and greater expressive range: the Eroica has extended movements, bold thematic development and wide dynamic contrasts, while the Fourth is more compact and classically balanced.
