The paper follows the discursive path of one of the dominant, and yet forgotten, terms in the history of ideas - that of?degeneration.? The richness of uses and various illuminations of the term, as well as its discursive dispersion and blurring, can be seen from the mid 19th until the first decades of the 20th century. The term was almost inescapable in studies of thinkers from various fields starting in the middle of the 19th century, it was successfully adopted from (...) French, Italian and British medical terminology into the art discourse of modern European societies. By focusing on music, the given term became permanently tied to thinking about relations of music and society in the German-speaking world. In a complex discursive development of the term, the author necessarily made certain choices, paying special attention to the Austro-Hungarian psychologists, Max Nordau who carried the concept of?degeneration? from the medical to the art sphere. The debate regarding the?degeneration of music,? was developed chronologically, starting from the Second Reich. While Wagner developed a theory of?degeneration? and its overcoming through?regeneration,? he was still considered?degenerated.? The given example reveals the complexity of the problem we face when we study the concept of?degeneration of music.? The consideration is completed with a glance at the life of?degenerated? musicians and music during the Weimar Republic, that is, their interpretation in the Third Reich. (shrink)
