"The Oceanides" is a single-movement tone poem for orchestra written in 1913–14. The piece, which refers to the nymphs in Greek mythology who inhabited the Mediterranean Sea, premiered on 4 June 1914 at the Norfolk Music Festival in Connecticut with Sibelius himself conducting. The work (in D major), praised upon its premiere as "the finest evocation of the sea ever produced in music", consists of two subjects Sibelius gradually develops in three informal stages: first, a placid ocean; second, a gathering storm; and third, a thunderous wave-crash climax. As the tempest subsides, a final chord sounds, symbolizing the mighty power and limitless expanse of the sea.
