Daniel Carlsson is born in 1980 in Sweden.

He began his education at the Royal Danish Academy in 2002 as a tenor and graduated in 2008. During the course of his studies he decided to change his voice from tenor to counter tenor strongly encouraged by baroque specialists such as Jacob Lorentzen and Jill Feldman. He received his singing education from Margrethe Enevold, Bodil Gümoes and Tony Landy and has concurrently attended master classes with Roger Vignoles, Martin Isepp and Jill Feldman among others.

Since he began singing counter tenor in 2007 he has been much in demand as a soloist both in Denmark and Sweden. Recently he appeared as soloist in J.S. Bach cantatas with Trinitatis Cantory and the conductor Per Enevold, in Bach's St. John Passion and in Zelenka's Lamentations both in Holmen's Church with conductor Jacob Lorentzen.

In 2008 he also appeared as soloist with Holmen's Cantory in Charpentier's Messe de Morts at Cuenca Baroque Festival in Spain. Later that year he sang Pergolesis Stabat Mater in Oslo and Bach's Christmas Oratorio in Sweden as well as Bach's B-minor mass with Sønderjylland Symphony Orchestra in february 2009.

2009 starts with a duet concert with baroque soprano Anna Jobrant Dalnäs in The Royal Naval Church in Copenhagen, Denmark. Other future engagements include the role of Amor in Monteverdi's L'incoronazione di Poppea at Drottningholm Cuort Theatre.
