In the previous lectures, which made up the cycle “Classics of Russian Music of the 20th Century”, the works of Sergei Rachmaninov, Igor Stravinsky, Sergei Prokofiev, Nikolai Myaskovsky, Dmitry Shostakovich, Aram Khachaturian, Georgy Sviridov, Rodion Shchedrin and Alfred Schnittke were examined. Let us supplement this panorama with two final lectures: the first is intended to extend the range of composers’ names, the second will be devoted to an overview of 20th century music with an outlet into the universal space. As it is well-known, since the time of Peter the Great, who established St. Petersburg, two capitals coexisted in Russia, each of which possessed its own face and style, among other things, in the creation of music. By the end of the 19th century, two compositional schools had developed: the St. Petersburg school, the core of which was the “Mighty Handful”, and the Moscow school, headed by Piotr Tchaikovsky. During the 20th century, these schools continued their fruitful interaction. Among the names presented in the main sections of my lectures, Stravinsky, Prokofiev, Myaskovsky, Shostakovich, Sviridov began their activities in St. Petersburg- Petrograd-Leningrad, and later they became Muscovites (except for Stravinsky, who lived abroad from the early 1910s). In the second half of the 20th century, the leaders of the musical process in Russia were the Moscow composers Rodion Shchedrin and Alfred Schnittke, along with whom many other names can be mentioned, including Edison Denisov, Sofia Gubaidulina and Vladimir Martynov. Representatives of the Leningrad school continued to make a significant contribution to the treasury of Russian music. The following short overviews of the works of Sergei Slonimsky and Valery Gavrilin will testify to this. In addition to the two capitals, composers from a number of other cities in Russia, primarily, those with conservatories, have worked tirelessly in the field of the art of music, which has significantly expanded the scale of the panorama of the musical art in our country — the creative heritage of Elena Gokhman is cited as a characteristic example.
