Music in Nazi Germany, like all cultural activities in the regime, was controlled and "co-ordinated" (Gleichschaltung) by various entities of the state and the Nazi Party, with Propaganda Minister Joseph Goebbels and the prominent Nazi theorist Alfred Rosenberg playing leading – and competing – roles. The primary concerns of these organizations was to exclude Jewish composers and musicians from publishing and performing music, and to prevent the public exhibition of music considered to be "Jewish", "anti-German", or otherwise "degenerate", while at the same time promoting the work of favored "Germanic" composers, such as Richard Wagner and Anton Bruckner. These works were believed to be positive contributions to the Volksgemeinschaft, or German folk community.
