注释,注释: The article explores the genre of string quartet on the example of Beethoven and Shostakovich in the aspect of intonation and thematic connections, as well as the parallels of creativity of both composers. The author gives examples of thematic, interval, intonation and textural-melodic quoting of Beethoven's works in Shostakovich's quartets. Russian culture and Beethoven's influence is revealed, in particular, in relation to working with the material of Russian songs in quartets written by order of Count Razumovsky. The author reveals Shostakovich's attraction to Beethoven's work, the closeness of his compositional style and ideas in terms of conceptuality, architectonics, the use of musical and expressive means and a tendency to dynamic onslaught. The methodology of the research is based on the analysis of historical materials, musical articles, concepts of outstanding historians and music theorists. The main contribution of this study is the identification of thematic and semantic connections between the quartets of Beethoven and Shostakovich. The author concludes that Shostakovich often turned to Beethoven's work, used his methods and techniques of working with the material, the structure of the cycle, included allusions to themes, intonations in his quartets, and even used whole textured excerpts from Beethoven's music – and he made it through the prism of his creative style. The novelty of the article lies in the identification of the connection between Beethoven's work and Russian music, the composer's use of melodies of Russian songs in "Russian Quartets", as well as intonation-thematic parallels between the quartets of Beethoven and Shostakovich. In addition, the article reveals the special role of the performer in the work on the quartet of both Beethoven and Shostakovich.
