Rationalizing the Revolution: Jazz in Hanns Eisler’s <i>Kampfmusik</i>

Abstract Hanns Eisler’s Kampfmusik , his revolutionary music for the working class, is famous for its rhythmic energy. Its steady beat has been understood as a legacy of the military march. I argue that this ‘Eisler Bass’ was instead ‘refunctioned’ from interwar German jazz. Using jazz pedagogical manuals to demonstrate how Eisler adapted the steady beat, I position Eisler’s writings and music within discourses of rhythm and rationalized factory labour. While this was central to Eisler’s political ambitions, it also led to his music participating in a larger practice of erasure of racial difference typical of the German Communist Party.
