The purpose of this work is to attract an attention to little – known publication of a pianist and musical expert Sofiia Dnistrianska (1882–1956) about outstanding Ukrainian composer Stanislav Liudkevych (1879–1979), where his personality as a famous representative of modern Ukrainian music was represented hardly for the first time outside of Ukraine. The generalized characteristics of composer’s work was also shown. Methodology of the research consists of combination of cultural-historical method (elucidation of the composer’s work and its estimation in the historical context) and origin learning method (processing of archival documents). Scientific novelty of the article was caused by the fact that such archival materials were added to scientific circle, as: correspondence of S. Liudkevych and S. Dnistrianska about the article in German language newspaper “Prager Presse” (Prague city, Czech Republic), which was published on 19 May, 1925 on the occasion of the 25th anniversary of S. Liudkevych composer activity. The translation of the article from the German was done by the author of this research. Controversy, which expanded around this publication of S. Dnistrianska, was about interpretation of national factor in music activity. S. Liudkevych reacted delicately by making notes in encyclopedic editions about himself. The question of national style, which was within sight of S. Liudkevych as not only the composer but also as the musical expert (let us recollect his article “Nationalism in music”, 1905), became basis for analytical researches of Ukrainian scientists Ivan Liashenko and Oleksandr Kozarenko. Conclusions of the proposed research work result in drawing attention to understanding of the national music culture problem. The results of the research give opportunity to develop investigations of the history of national music.
