Musicology Annotation << Back The Avant-Garde technique of aleatory compositions as a means of expressiveness in music of the second half of the 20th century Svetlana G. Farkhutdinova The situation in the musical art of the 20th century has been changing because of the emergence of "avant-garde" opuses that are defi antly opposed to the traditional norms of music. The new reality requires development of new approaches. Identifi cation of the models of texture space organization in relationship and interaction with composition techniques, i.e. sonorism and pointillism, leads to understanding of the specifi c characters of the world spatial images and allows tracing the infl uence of the atomicity on the density of the texture with the addition of such qualities as weightlessness and tenuousness. It is no doubt that at the beginning of the 20th century it was quite possible to come across the term "composition" (e.g. in the works by V. Kandinsky). So no wonder that since the second half of the 20th century composition occupies a prime position in music not only at the level of form, but also at the level of the author's name of the composition, which brings to its interpretation some additional semantic counterpoint. The question of the fi nal result is that of compositional structure of new semantic, dramatic, philosophical and technological ideas. For each composition it is necessary to bring up, to invent or to discover something new, without repeating if possible. That leads to polystylism with an entirely different way of thinking, where a composer can take any previously written music (e.g. that of classics, romantics, etc.) and use it as a source for composing a new work, introducing and tying up together various historical and cultural spaces. Keywords: music of the second half of the 20th century, avant-garde technology, musical composition, aleatoric, sonoristic, thematic multiplicity. Contacts: E-mail: sve10.71@mail.ru Pp. 03-08.
