Ernst Krenek’s Karl V is a testimony to the anachronistic—in the best sense of the word—exploitation of the memory of the Holy Roman Empire, or the imperial idea of Charles V as the composer understood it, reflecting the unrealized possibility of a transformation of the medieval concept of empire into a contemporary form.
In its interpretation of the Holy Roman Empire, the opera builds a bridge to the world of values of the Austrian corporative state, which sought to attribute a special mission to Austria by linking it with the supranational idea of the Habsburg Empire. This involves a distinct rejection of the National Socialist idea of empire. On the musical level, this is expressed by the use of the proscribed 12-tone technique. which in various respects corresponds to the conceptual theme of the work.
Krenek’s position can be defined both from the standpoint of music-art and of philosophy-politics, as that of a border-crosser, one which resists classification in any specific direction.
This according to “Die Idee des Reiches in Ernst Kreneks Bühnenwerk mit Musik Karl V, op. 73 (1933)” by Raymond Dittrich, s essay included in Was vom Alten Reiche blieb…: Deutungen, Institutionen und Bilder des frühneuzeitlichen Heiligen Römischen Reiches Deutscher Nation im 19. und 20. Jahrhundert (München: Bayerische Landeszentrale für Politische Bildungsarbeit, 2011, pp. 421–33).
