Аннотация: The subject of the research is the problem of time in the new music, considered in the context of philosophical reflection. The category of time is considered through a prism of philosophy and new music. Two readings of time - time Chronos and Eon's time, according to the statement of the French philosopher G. Deleuze, are opposite. Music is defined substantially by the ordered current of time.Research method is based on a comparative analysis of philosophical concept and aesthetic-philosophical aims composers of the second half of the twentieth century. These settings are decisive in the spatial organization of the musical fabric. Structuring musical time and its various concepts is considered in a context of musical ideas of the Italian composer S. Sciarrino. Among compositions S. Sciarrino of analyzed in article, "Vanitas" - a huge paraphrase of a canzone of Stardust where the author addresses to emptiness Eon's metaphor. Opposing to Chronos and Eon as two forms of time, properties of the first is that it is limited and infinite. Eon is also boundless as the future and the past, but as an instant. S. Sciarrino's aspiration to the musical forms, adequate processes of activity of consciousness, and memory the Theory of duration of A.Bergson becomes one of the corresponding conclusions of article, is also connected with his theory of memory. By means of properties of memory the past and the present aren't mutually, they unite unity of knowledge.Scientific novelty of the paper is that for the first time analyzed the works of Sciarrino in the context of space and time, and for the first time carried out a comparative analysis of the music of the second half of the twentieth century, from the standpoint of philosophical categories.
