There is another definition of "Avant-gardism" that distinguishes it from "modernism": Peter Bürger, for example, says avant-gardism rejects the "institution of art" and challenges social and artistic values, and so necessarily involves political, social, and cultural factors. According to the composer and musicologist Larry Sitsky, modernist composers from the early 20th century who do not qualify as avant-gardists include Arnold Schoenberg, Anton Webern, and Igor Stravinsky; later modernist composers who do not fall into the category of avant-gardists include Elliott Carter, Milton Babbitt, György Ligeti, Witold Lutosławski, and Luciano Berio, since "their modernism was not conceived for the purpose of goading an audience."Larry Sitsky, Music of the Twentieth-Century Avant-Garde: A Biocritical Sourcebook (Westport, Conn: Greenwood Press, 2002), xv. .
