 It is certainly true that Shostakovich borrows extensively from the material and styles both of earlier composers and of popular music; the vulgarity of "low" music is a notable influence on this "greatest of eclectics". McBurney traces this to the avant-garde artistic circles of the early Soviet period in which Shostakovich moved early in his career, and argues that these borrowings were a deliberate technique to allow him to create "patterns of contrast, repetition, exaggeration" that gave his music the large-scale structure it required.
