Beethoven's Third Symphony, originally entitled "Bonaparte", now bears the title "Eroica" ("Heroic"). Napoleon promised an Enlightened Europe but ultimately Beethoven was disillusioned by him. This handbook treats the politics, aesthetics, reception, and musical meaning of this decisive work, which, because of its unique design, powerfully expanded the potential of symphonic expression. Beethoven's ideals, derived largely from the writings of Friedrich Schiller and clearly perceived already by the composer's contemporaries, are readily apparent in the music.
