Musicology Annotation << Back On the General Bases in the Development of Music and Natural Sciences of New and Newest Time Irina Tukova Traditionally, the art of music and science are seen as two completely separate spheres of knowledge of the world. The article makes an attempt to form an idea of their development as a integrated system. Chosen period — from the XVII century to the present moment. At this time in the natural sciences were established and developed two paradigms — the classical (mechanistic) and non-classical (relativistic). The generality of musical art of modern times leads to the formation and development of a single composition technique — key functional system. The last century has changed dramatically this unity by introducing various principles of selection and organization of material. The article commonality of musical art and science is considered in two ways. First — chronological. Recorded events, demonstrating a paradigm shift. The second — a principle of understanding the world. An attempt is made to identify the main features of the natural sciences law characteristic of classical and non-classical paradigms. Their features are projected on the principles of musical material. This approach allows us to understand the underlying causes of co-existence in the XX century — the beginning of the XXI century, a variety of composition techniques, ways of structuring essays etc. The main methodological approach is proposed to use the principle of complementarity, introduced in science by N. Bohr. Keywords: art of music, natural science, New Time, Newest Time, analogy, the law, the principle of complementarity, the technique of composition. Contacts: E-mail: tukova@ukr.net Pp. 03-08.
