Haidenko I. The Role of Computer Technologies in Contemporary Composer Practices.

The dissertation examines the use of computer technologies in composer practices and evaluates their active impact on composer processes and music composition as an integral entity. The first section discusses the aspect of use of computers in music. The core of analysis is computer modeling of composer processes and performer renditions, the newest creative possibilities and use of computers in teaching music. The second section seeks to define the notion of "music computer technologies" by relating them to familiar music definitions. technologies are similar structurally and functionally and define the ways of generating, organizing, developing, recording and realizing music by the human creator. The difference is in their nature. Thus, whereas composer techniques remain within the boundaries of human activities, music computer technologies are reflections of such techniques in the minds of computer programmers. Being an abstract model of the existing composer techniques, a sort of a hypertechnique,they include them as special cases. The study offers a series of new definitions of music computer technologies and composer techniques that have not been previously discussed in scientific literature. The third section focuses on music computer technology practices which are analyzed as per the elaborated classification system resting on the structural analogy to composer processes. The conclusions prove that computerization powers objectively affect the composer processes, derive the new methods of handling the music matter, and evoke new dramaturgical organization methods thus resulting in certain changes in music composition which would be impossible without computer technologies.
