Pierrot Lunaire
He was a Symbolist poet. His published works include "Pierrot lunaire: Rondels bergamasques" (1884), a poem cycle based on the commedia dell'arte figure of Pierrot, and "La Guirlande des Dieux" (1910). The composer Arnold Schönberg set a German-language version (translated by Otto Erich Hartleben) of selections from his "Pierrot Lunaire" to innovative atonal music. In a different, late romantic style, some of Hartleben's translations found their way into the vocal works of Joseph Marx.
