Born in Bosjökloster, he was an organist (completing his examinations in 1909),[2] and as a young man a concert pianist and music teacher.
In 1920 he studied on a scholarship in Berlin, Dresden, Vienna and Paris, which brought formative contacts with Arnold Schoenberg and Paul Hindemith.
[1] While his earlier works display the influence of Sibelius, he soon led the way for Swedish composers to move away from the late Romantic style and became considered as somewhat radical.
[2] His violin concerto features as part of the sound track of the 1936 film Intermezzo, directed by Gustaf Molander and starring Ingrid Bergman and Gösta Ekman.
He also composed music for the 1944 film Hets (known in English as either Torment or Frenzy), directed by Alf Sjöberg from a screenplay by Ingmar Bergman.
