Jean Sibelius was a Finnish composer born on December 8, 1865, in Hämeenlinna, Finland. He is best known for his symphonies and tone poems, which reflect the landscapes and folklore of his homeland. Sibelius played a significant role in establishing a national identity for Finland through his music, particularly during the country's struggle for independence from Russia. Sibelius's most famous works include the Finlandia and the Violin Concerto in D minor. His style evolved over time, moving from late Romanticism to a more modern approach. He composed seven symphonies, with the Seventh being his last, completed in 1924. Sibelius passed away on September 20, 1957, leaving a lasting legacy in classical music.
