Composed by Léo Delibes for the opera Lakmé, premiered in Paris in 1883, the Flower Duet appears in Act 1 as Lakmé and her servant Mallika sing while gathering flowers by a river. Its French opening, Sous le dôme épais, became familiar far beyond opera houses through films, television and advertising, most famously a long running British Airways campaign. That exposure turned a short operatic excerpt into a widely recognised shorthand for calm, luxury and refinement, which is why creators still borrow it for beauty, romance and gentle parody today.
