The turbulent period in Europe before and during World War I was one of the main causes of development in the Arts. The old Romantic world was collapsing in a most violent manner. Composers responded to the changes and aggression differently. Leos Jancek composed the Violin Sonata as a reaction to the war, and with intensified nationalistic feelings. The characteristic compositional style found in his Violin Sonata was a result of the influences he was exposed to during his growth as a composer, and his original ideas conceived while researching folk music of his native Moravia and speech inflections in the Czech language. This study compares Janceks Violin Sonata to those of Brahms and Debussy on historical, social, and stylistic levels.
