The thesis is devoted to the development of ensemble genres of Ukrainian cello music in the contest of pan-European stylistic trends evolution. The coverage of the national cello-playing evolution was carried out in the procedural motion within the chamber ensemble culture. There were marked three historical periods of cello ensemble art of Ukraine according to the forms of music playing, type and the means employed in the composition (the end of XVII-XIX century, the beginning of the XX century - 60-ies of the XX century, the last third of XX century - the beginning of XXI century). The identification of stylistic trends characteristic to each stage of the development led to the definition of the phenomena of sentimentalism, romanticism, Biedermeier art, neoclassical, neobaroque, neofolklorics, neostylistics etc. The process of the cello-playing formation and specificity in Ukraine in the XVIII-XIX centuries were studied in the comparative analysis with the development of European cello school. That caused an appeal to issues of pedagogy and methodology of cello playing, the role of the concert-virtuoso culture in the process of instrumental art professionalization, the national factor and European influences, the manifestation of peripheral, institutionalization, etc. Considerable attention is paid to the features of cello art formation in different regions of the country. The process of cello-playing professionalization is traced, the basis of which in Ukraine has become a highly amateur music-making. This was reflected in determining of the value and role of amateur cellists, whose performing activity promoted professional level of domestic Cello Art (A. Galenkovsky, N. Golitsyn, M. Jasinski, V. Kologrivov, P. Seletsky, A. Storozenko). The feature of Ensemble Cello Performances of the professional period resulted in the need to highlight the creative ways and the evaluation of the first professional cello players, such as B. Berezhnitsky, D. Danchovsky, P. Pshenichka, A. Slyadek, A. Volfstal (Lviv), O. Belousov, M. Bukinik, S. Glaser, A. von Glenn, I. Dubinsky, J. Press (Kharkiv), V. Alois, V. Gutor, V. Meshkov, A. Verbov, L. Zelenka (Odessa), L. Albrecht, S. Kozolupov, F. von Mulert, S. Vilkonsky (Kiev). The stylistic features of the Ukrainian cello music ensemble genres identified by the analysis of musical style and performing technologies of ensemble works of the Ukrainian composers and their comparison with samples oPf Western-European music (end of XVIII-XIX centuries - L. van Beethoven, D. Bortniansky, J. Brahms, I. Lizogub, M. Lysenko; the first half of the twentieth century - F. Akimenko, V. Barvinsky, V. Kosenko, S. Lyudkevych, B. Lyatoshynsky, I. Raczynski and others; 60-ies of the XX - early XXI century - I. Alekseichuk, V. Bibik, V. Gubarenko, Y. Ischenko, I. Karabits, V. Larchikov, E. Petrichenko, I. Polsky, E. Stankovic, A. Shtogarenko etc.). The investigation of the basic steps of stylistic changes and synthesizing events in the national musical art of the second half of XX - beginning of XXI century become possible by studying of the cello ensemble heritage of Y. Ishchenko.
