Written in 1880 and first performed in 1882, the 1812 Overture commemorates Russia's defence against Napoleon's invasion in 1812. Tchaikovsky saved the full Russian hymn for the finale, layering it with bells and cannon effects that have made the ending instantly recognisable. The piece spread through concerts, films, fireworks displays and television as shorthand for a triumphant conclusion. Online, editors reuse this finale for mock epic wins, formal celebrations and any scene that needs a sense of a battle finally won and a feast about to begin.
