Claus-Steffen Mahnkopf (born 22 October 1962) is a German composer, editor and author.
Claus-Steffen Mahnkopf was born in Mannheim, Germany, and studied composition with Brian Ferneyhough, Klaus Huber and Emanuel Nunes and music theory at the music academy in Freiburg where he graduated in 1992. At the same time, he studied musicology, philosophy with Jürgen Habermas and sociology at university. Later he was influenced by Habermas's antagonist Peter Sloterdijk and appropriated the idea of a philosophical explanation of the female orgasm (which lacks biological necessity in terms of procreative function) from an email novel Sloterdijk had published three years earlier.
In 1993 Mahnkopf was awarded a doctorate in philosophy for his dissertation on Arnold Schönberg. For his compositions Mahnkopf won numerous international prizes, among them the Gaudeamus International Composers Award in 1990, the composition prize of the city Stuttgart and the Composers Award of the Ernst von Siemens Music Foundation in 1998. Mahnkopf went to Rome (Villa Massimo), Italy, Venice (Centro Tedesco di Studi Veneziani), Italy, and Basel (Paul-Sacher-Stiftung), Switzerland, on scholarships. From 2001 until 2005 Mahnkopf worked regularly at the Experimental Studio of the SWR. Since 2005 Claus-Steffen Mahnkopf has taught composition at the University of Music and Theatre "Felix Mendelssohn Bartholdy" in Leipzig. His music has been performed by many ensembles, like SurPlus or ensemble recherche at international festivals, for example at the Salzburger Festspiele or at the Flanders Festival. Among musicians who regularly perform his works are oboist Peter Veale, Sophie-Mayuko Vetter, Carin Levine, James Avery and Frank Cox.
In 1995 Mahnkopf was one of the founders of the Gesellschaft für Musik und Ästhetik (society for music and aesthetics) at Freiburg and he is also one of the editors of the society’s magazine. Mahnkopf has worked as music theory teacher and as consultant for opera houses and he has published many essays in musicological magazines.
In 1999, Mahnkopf married professor doctor Francesca Yardenit Albertini (1974–2011), a Jewish philosopher of religion.
