Statement of the problem. The centuries-old development of the genre of piano caprice (capriccio), which led to its flourishing in the work of romantic composers, is considered as an integral part of the genre system in Western European piano music. Insufficient study of Mendelssohn’s piano works, in particular caprices, determines the relevance of the research. The purpose of the article is to generalize stylistic qualities of the composer’s piano caprices in the context of genre evolution and their performance features. Analysis of research and publications. The genre of caprice is studied in the historical research of T. Livanova (1983), who equates the form of fantasy and capriccio-ricercare. V. Protopopov (1979) reveals the connection between fantasycapriccio and fugue in the early 17th century. K. Agisheva (2007) examines the historical aspects of the study of the capriccio genre. Modern Western European researchers, analyzing the genre of piano caprice, emphasize that its musical texture is filled with elements of vocal lyrics and mood swings (Lewandowski, 2017; Keym, 2009). At the same time, the issues of performance features remain unclear. Methods. Complex methodological approach applied in the article (historical, genre, structural-functional, performаnce research methods) allows us to trace the development of caprice from the Baroque era to Romanticism and conduct an intonational-dramatic analysis of Mendelssohn’s works in accordance with the following criteria: musical form (dramaturgy), textural presentation, thematic development, tempo-rhythmic characteristics, nature of thematism. Analysis of recent research and publications. Baroque caprice is a work of polyphonic composition and improvisational construction (J. S.Bach, G.F. Handel, I. Sweelink, J. Frescobaldi). In the era of Viennese Classicism, caprice was not very popular due to its improvisational, bizarre nature, contradicting to the aesthetic ideals of the time. The genre of piano caprice became widespread in the era of Romanticism in the works of F. Mendelssohn, whose distinguished style is marked by virtuosity, melody, grace, sentimentality, clarity of presentation. Among the works of F. Mendelssohn there are seven caprices for solo piano and with orchestra. The intonational-dramatic analysis of Mendelssohn’s piano caprices makes it possible to trace the main stylistic qualities of the genre and to reveal its performance features. Conclusions. The work outlines the stylistic traits of Mendelssohn’s piano caprices ассording to such parameters: – compositional structure of his piano caprices is a one-movement composition or a cyclic one, composed of two or three movements; – texture of the music is determined by polyphonic orchestral elements and broad cantilena themes; – thematic development is based on repetition, variability or variation; – tempo-rhythm is characterized by three-beat pulsation, syncopation of rhythm, sharp accentuation; – thematicism is determined by synthesis of lyrical and decisively acting images inherent in the style of Mendelssohn. Hence, the main task for the performer is clarity, expressive intonation of the melody in combination with a “pearl” light touch and energetic dynamic tempo rhythm.
