The Reichsmusikkammer (translatable variously as "Reich Music Chamber," "State Music Institute," or "State Music Bureau") was a Nazi institution. It promoted "good German music" which was composed by Aryans and seen as consistent with Nazi ideals, while suppressing other, "degenerate" music, which included atonal music, jazz, and music by Jewish composers. The Institute was founded in 1933 by Joseph Goebbels and the Reichskulturkammer (State Bureau of Culture), and it operated until the fall of the Third Reich in 1945.
One of the Institute's primary goals — that of extolling and promoting "good German music", specifically that of Beethoven, Wagner, Bach, Mozart, Haydn, Brahms, Bruckner and the like — was to legitimize the claimed world supremacy of Germany culturally. These composers and their music were re-interpreted ideologically to extol German virtues and cultural identity.
Music and composers who did not fall into the RMK's definition of "good German music" were deprecated and then banned. The Institute proscribed various great composers of the past, including the Jewish-by-birth composers Mahler, Mendelssohn, and Schoenberg, and also Debussy, who had married a Jew. The music of politically dissident composers such as Alban Berg was also banned. And composers whose music had ever been considered sexually suggestive or savage, such as Hindemith, Stravinsky and the like, were denounced as "degenerate" and banned.
