Context is key here. Shostakovich had survived the terrifying denunciations of 1936 and 1948. By 1957, he was finally able to write music without the immediate fear of the Gulag. The result was a work that is undeniably lighter than his tragic Fifth or Eighth Symphonies. However, Shostakovich never wrote anything "purely" light. Even in his happiest moments, there is often a sense of irony or a glimpse of the shadows.
