Creative Ideas and Aesthetic Emotions in the Sonata for Violin and Piano by Leoš Janáček

Apart from several works that are emblematic of the 20 th -century operatic repertoire, Leoš Janáček is also the author of works for violin and piano, of which the Sonata catalogued as JW VII/7 is the most prominent.Through the historical overview below, this study aims to highlight its place among the chamber works of the Czech composer, with an emphasis on the chronology of the composer's multifaceted activity between 1914 (when he began composing it) and 1922 (when its final version saw the light of day).The analysis explores the depths of the creative process and, apart from dealing with the instrumental and compositional techniques and procedures, it focuses on messages, emotions and ethos.The research dwells on a few details related to sonority, especially to the ancestral, archetypal and folk vein of the music, and on the way the piano and violin, in turn, must make us hear a cimbalom.We see that the traditional sonata form allows for modern creative interpretations, anchored in the vivid substance of folklore, and no less in the composer's fertile imagination.For performers, Leoš Janáček's Sonata for Violin and Piano is not a technical challenge, but rather the path towards conveying the emotions of one of the most original composers of the 20 th century.
