Zlata Tkach’s Concerto for Piano and Orchestra as a Culmination of the Composer Symphonic Thinking

The purpose of the article is to characterize Zlata Tkach’s Piano Concerto as the culminating composition in the genre of the composer’s symphonic music. The research methodology is based on the method of complex musicological analysis, due to which, the role of this work in the system of memorial genres of the author is determined, typical style features of her work late period are revealed, the thematic structure of the Concerto is characterized from the position of the manifestation of the principle of dialogicity and monothematism. The scientific novelty of the research is that for the first time, intonation processes in a Piano Concerto by Z. Tkach are systematically analyzed and the correlation of its traditional and innovative features is characterized. Being by genre attribution an opus with a pronounced desire to use modern means of expression, the concert is distinguished by the manifestation of the principle of microthematism and textural thematism. In the dramaturgical solution, the author conducts a constructive search in dynamic, timbre and rhythmic comparisons. At the same time, the intonational unity between the sections of the form, being the development of the romantic principle of poetry, is expressed in the form of monothematism. Conclusions. The creative method of Z. Tkach manifests itself in the synthesis of tradition and experiment. This is confirmed by the intonation-thematic structure of the Piano Concerto, in which the convergence of contrasting material contributes to the formation of an integral musical and dramatic concept. The motifs that form the basis of the monothematism complex establish intonation arches between the sections of a one-part composition, fastening them and subordinating them to a common plan. Important importance belongs to the opposition of the roles of the participants in the performance. Their dialogical activity is manifested in a peculiar way by the composer, primarily in the dialogue between the soloist and the orchestra: the interweaving of two contrasting figurative spheres is realized primarily in terms of content. The principle of monothematism is manifested especially vividly in the characterization of tragic reflections, painful reflections on the eternal conflict of the creative personality with the surrounding world, leading to a deep understanding of what exists. The other embodies the dynamism of life, dominating in the culmination of ‘action’, the accumulation of energy. Both the piano and the orchestra are equally involved in the development of both figurative principles. The resulting translational, purposeful movement towards the finale determines, along with the principle of monothematism, the integrity of the entire composition.
