Jean Sibelius (/sɪˈbeɪliəs, -jəs/; Swedish pronunciation ), born Johan Julius Christian Sibelius (8 December 1865 – 20 September 1957), was a Finnish composer and violinist of the late Romantic and early-modern periods. He is widely recognized as his country's greatest composer and, through his music, is often credited with having helped Finland to develop a national identity during its struggle for independence from Russia.
The core of his oeuvre is his set of seven symphonies which, like his other major works, continue to be performed and recorded in his home country and internationally. His best-known compositions are Finlandia, the Karelia Suite, Valse triste, the Violin Concerto, the choral symphony Kullervo, and The Swan of Tuonela (from the Lemminkäinen Suite). Other works include pieces inspired by the Finnish national epic, the Kalevala, over a hundred songs for voice and piano, incidental music for numerous plays, the opera Jungfrun i tornet (The Maiden in the Tower), chamber music, piano music, Masonic ritual music, and 21 publications of choral music. Throughout his career, the composer found inspiration in nature and Nordic mythology, especially the heroic legends of the national epic, the Kalevala.
