Abstract: The object of research in this article is the piano cycles of the Italian composer and pianist Alessandro Longo (1864-1945). The subject of the study is the continuation and development within the framework of this genre of romantic traditions laid down by romantic composers F. Chopin and R. Schumann. Alessandro Longo turned to writing piano cycles throughout his life. These works are distinguished by significant artistic merits. The author of the article examines in detail such aspects of the topic as the creation of the integrity of the cycle on the basis of tonal, figurative-emotional, genre connections between the plays. Within the framework of the suite-type cycle, he reveals the features of programmaticity found in the names of the plays and their arrangement in cycles. Special attention is paid to the analysis of piano cycles of etudes, which are interpreted by Longo not so much as a genre aimed at practicing techniques to improve professional skills, but as a sketch, romantic piano miniature. The author uses an integrated approach, including system-historical and comparative methods of analysis. The basis for the study of the research was the method of musical theoretical analysis, including thematic, stylistic, structural and compositional aspects. The author's significant contribution to the study of the topic lies in the introduction to musicological usage and understanding of a significant layer of Italian musical culture of the late XIX – early XX century. Alessandro Longo's piano cycles, which are in demand in the performing practice of Western European musicians and are of interest for pedagogical practice, are little known to domestic performers and have not been considered in musicology. This publication is the first study of A. Longo's piano cycles in the light of the implementation of romantic trends. As a result of the analysis, the author comes to the conclusion that the piano cycles of the non-sonate type by A. Longo continue the established traditions in the implementation of this genre, which is manifested in the appeal to certain principles of cyclization: tonal logic, genre, tempo, tonal, emotional-figurative connections between the pieces. At the same time, they reveal an identity peculiar to both the Italian national culture as a whole and to this author, which is manifested in melodiousness, melodiousness (including in cycles of sketches), as well as emotional saturation and theatricalization.
