Finlandia, Op. 26 is a symphonic poem by the Finnish composer Jean Sibelius. The first version was written in 1899, and it was revised in 1900. The piece was composed for the Press Celebrations of 1899, a covert protest against increasing censorship from the Russian Empire, as the last of seven pieces, each performed as an accompaniment to a tableau depicting episodes from Finnish history.
A recurrent joke within Finland at this time was the renaming of Finlandia at various musical concerts so as to avoid Russian censorship. Titles under which the piece masqueraded were numerous, a famously flippant example being Happy Feelings at the awakening of Finnish Spring.
Most of the piece is taken up with rousing and turbulent music, evoking the national struggle of the Finnish people. But towards the end, a calm comes over the orchestra, and the serenely melodic Finlandia Hymn is heard. Often incorrectly cited as a traditional folk melody, the Hymn section is of Sibelius's own creation.
Sibelius later reworked the Finlandia Hymn into a stand-alone piece. This hymn, with words written in 1941 by Veikko Antero Koskenniemi, is one of the most important national songs of Finland (though Maamme is the national anthem). With different words, it is also sung as a Christian hymn (Be Still, My Soul; also Hail, Festal Day), and was the national anthem of the short-lived African state of Biafra (Land of the Rising Sun).
