"Das Judenthum in der Musik" (German for Judaism in Music, but perhaps more accurately understood in contemporary language as Jewishness in Music), is an antisemitic essay by composer Richard Wagner which criticizes the influence of Jews and their "essence" on European art music, arguing that they have not contributed to its development but have rather commodified and degraded it. It alleges that Jews infiltrated the music industry not through their artistic capabilities, but because of their control over financial resources. In particular it discusses the music of Jewish composers Felix Mendelssohn and Giacomo Meyerbeer, acknowledging its technical proficiency but criticizing it as lacking genuine artistic passion. According to Wagner, authentic art is rooted in immersion within the organic life of a culture, and Jews, indicated as being outsiders to this culture, are capable of only making artificial or superficial contributions. It was first published under a pseudonym in the Neue Zeitschrift für Musik (NZM) of Leipzig in September 1850. It was republished in 1869, this time bearing Wagner's name, with expanded commentary on the original publication's purpose, response and the purported negative impact on Wagner and his associates' careers.
