Danish soprano Sofie Ottosen was educated at the Juilliard School of Music in New York, in the Soloist Class at the Royal Danish Academy of Music, and at the Opera Academy at the Royal Theater in Copenhagen. She made her debut as Frasquita in Bizet's Carmen in 1992 at the Danish Royal Opera, where she has since sung the roles of Barbarina in Mozart's The Marriage of Figaro and the Niece in Britten's Peter Grimes. However, her true breakthrough came in the guise of Rosalinde in Strauss' Die Fledermaus at the New Theatre in Copenhagen, a role she sang more than 70 times. It is in the arena of the operetta where she is most noted in her native country.
She has an active career as a soloist in Denmark, particularly in large choral works such as Handel's Messiah, Brahms' and Mozart's requiems, and Orff's Carmina Burana. She also has performed in Salzburg, Vienna, and Hamburg. She is equally at home in smaller settings and frequently sings with various partners, including John Venning with his Three Royal Tenors and his Royal Quartet.
Ottosen's recording company, Soprano Records, issued its first CD in 2005. Entitled H.C. Andersen & Trio Fabula, it was released as part of Hans Christian Andersen's bicentenary celebrations and contains both dramatic recitations and vocal renditions of the author's beloved fairy tales. In fact, Ottosen's performance of Prokofiev's The Ugly Duckling marks the first time that it has been recorded in Danish.
