The roots of the orchestra date back to the singer Emil Holm, who expressed a wish to establish a full-time symphony orchestra in Denmark. In collaboration with fellow musicians Otto Fessel, Rudolf Dietz Mann and Folmer Jensen, the orchestra was founded in 1925, with 11 players in the ensemble and conductor Launy Grøndahl having a leadership role, though without a formal title. The orchestra grew to 30 players within a year. The orchestra performed its first public concert was in 1927, and began to give weekly concerts in 1928. In 1930, Holm recruited Nikolai Malko to a similar key role like Grøndahl as conductor with the orchestra, though again without Malko having a formal title. In 1931, the orchestra began to give concerts at the Stærekassen hall of the Royal Danish Theatre. After going into exile from Germany in the 1930s, Fritz Busch worked extensively as a major conductor of the orchestra in parallel with Malko, though again with no formal title. By 1948, the orchestra had attained membership of 92 musicians.

The first conductor to have the formal title of principal conductor with the orchestra was Herbert Blomstedt, from 1967 to 1977. Blomstedt now has the title of æresdirigent (honorary conductor) with the DNSO. The second principal conductor, after an interregnum of 9 years, was Lamberto Gardelli, from 1986 to 1988. Thomas Dausgaard, who was the DNSO's principal guest conductor from 2001 to 2004, became principal conductor of the DNSO in 2004, the first Danish conductor to hold the title. Past principal guest conductors of the DRSO besides Dausgaard have included Yuri Temirkanov, Michael Schønwandt, and Dmitri Kitaenko.

In 2010, the orchestra announced Søren Nils Eichberg as its first-ever composer-in-residence.

In February 2011, the DNSO announced the appointment of Rafael Frühbeck de Burgos as its next principal conductor, as of the 2012-2013 season. On 4 June 2014, Frühbeck de Burgos resigned as chief conductor of the orchestra, with immediate effect, in parallel with his retirement from conducting, because of health problems. He died just one week later. In August 2014, the orchestra announced the appointment of Fabio Luisi as its next principal conductor, effective in 2017.

The orchestra has recorded commercially for such labels as DaCapo and Chandos, including music of Danish composers such as August Enna, Niels Gade, Rued Langgaard, and Per Nørgård. The orchestra has also commercially recorded such composers as Johannes Brahms. Wikipedia
