Danish composer Carl August Nielsen was born on 9 June 1865 in Sortelung on the island of Funen. He was the seventh of twelve children born into a poor peasant family. His father, Niels Jørgensen, was a painter and folk fiddler, and his mother sang traditional ballads. Nielsen received a violin at six and taught himself melodies, composing a lullaby and a polka by age nine. At fourteen he enlisted as a bugler and alto trombonist in the 16th Battalion band in Odense. In 1884 he entered the Royal Danish Academy of Music, studying violin, piano, and composition until 1886, and premiered his Suite for Strings, Op. 1, in 1888 at age twenty-three.

After graduation, Nielsen served for sixteen years as second violinist under Johan Svendsen in the Royal Danish Orchestra, taking part in the Danish premieres of Verdi’s Falstaff and Otello. He later became Kapellmeister at the Royal Theatre (1908–1914) and conductor of the Copenhagen Musical Society (1915–1927), while teaching at the Royal Conservatory from 1916 until his death. His oeuvre includes six symphonies (1892–1925), concerti for violin (1911), flute (1926), and clarinet (1928), the operas Saul og David (1902) and Maskarade (1906), the Wind Quintet (1922), four string quartets, choral works, and more than a hundred Danish art songs. His style progressed from Brahmsian Romanticism to progressive tonality, bold dissonance, contrapuntal clarity, and polytonal explorations, forging a uniquely Danish voice within European modernism2.

Nielsen’s music, characterized by its expressive energy and organic thematic development, often reflects conflict, resilience, and the vitality of nature. His Sixth Symphony, Sinfonia semplice (1924–1925), exemplifies his late-career economy and structural ingenuity. He died of a heart attack in Copenhagen on 3 October 1931 at age sixty-six and was buried in Vestre Cemetery. Although he was perceived as an outsider during his lifetime, his works secured international prominence in the 1960s through advocates like Leonard Bernstein. Today, Nielsen is Denmark’s foremost composer, celebrated through the Carl Nielsen Museum in Odense, the complete Carl Nielsen Edition, and his enduring presence in concert halls and on the Danish hundred-kroner banknote.
