With the exception of Shostakovich's Lady Macbeth of the Mtsensk District, Soviet opera in the 1930s has been relatively little studied. Yet this was an era in which opera was vigorously promoted as an ideal Soviet form after more than a decade of criticism from radical proletarian groups. This article considers three main aspects of Soviet operatic culture in the 1930s. First, opera's emotional power was valued as a way to mobilise mass opinion and the opera house was increasingly seen as a highly ideological site. Second, whilst most of the work in founding a Soviet repertory was carried out at Leningrad's Malyi Opera Theatre, Moscow became increasingly involved as the decade continued. Third, Soviet opera was highly dependent on adaptations of socialist realist novels. This phenomenon of ‘transposition’ is seen here as an attempt to invest scores with an unimpeachable political message. Moreover, transposition was an ideal method of regulating ambiguous literary texts by condensing their cardinal features in dramatic form. Although the story of Soviet opera was largely one of failure, its study sheds important light not only on the development of the Russian operatic tradition, but also on the dynamics of Stalinist culture.
