[Intro: instrumental only — fortepiano and strings state a clear Classical theme, elegant and balanced] [Exposition: instrumental development — Mozart-like melody over Haydn architecture, themes conversing] [Development: fully instrumental — theme fragments, minor-key tension, Beethoven heroic build] [Recapitulation / Chorus of orchestra: full Classical orchestra, Eroica-scale climax, still in Classical form] [Outro: instrumental — theme returns in clarity, fortepiano last, hall resonance fading]
