In addition, Adorno has a strong interest in music. He studied music under V.A. Berg, specializing in music composition. During his stay in the United States, he worked for the new york Institute for Social Studies from 1938 to 1941, and also served as the director of the music department of the research project of Princeton Radio. In 1949, he published the monograph "New Philosophy of Music". After returning to Germany in 1952, he wrote a controversial paper, analyzed the works of R. Wagner, and thought that these works were the causes of Nazi. His masterpiece "Introduction to the Sociology of Music" was published in 1976 after his death. In this work, he regarded the dance form of jitterbug as a kind of deliberately induced external frenzy, and suppressed the internal frenzy that many young people felt during their adjustment.
