Josefine Opsahl (b. 1992) is a Danish composer and cellist whose work spans classical composition, electronic experimentation, and interdisciplinary performance. Based between Copenhagen and Berlin, she merges acoustic and digital soundscapes, often combining her cello with live electronics and sound design in her solo performances.
Opsahl studied both classical and contemporary music at the Royal Danish Academy of Music and Northwestern University (IL, USA), earning her Master’s degree in cello. She later completed composition studies in Contemporary Creative Art at the South Danish Conservatory.
Her work as a performer includes collaborations with ensembles such as Kottos and We Like We, as well as her 2022 solo release Atrium. As a composer, Opsahl has written for opera, ballet, and symphonic orchestra, including a cello concerto and large-scale works premiered at the Elbphilharmonie in Hamburg. Her opera Hjem was nominated for Opera of the Year at the 2023 Reumert Awards.
She is the recipient of several prestigious honors, including the 2022 Crown Prince Couple’s Stardust Award, the 2021 Léonie Sonning Talent Prize, and the Wilhelm Hansen Foundation’s Prize of Honor (2020).
Opsahl’s music is noted for its sensitivity to space, texture, and time—combining formal classical training with a contemporary, genre-defying curiosity.
