Probabilistic functionality in multimedia
Abstract.Functionality in music is understood as “expectation of emergence of certain elements of a piece of music with a certain degree of probability” (A.P. Milka). It is usually expressed as a system of inclination of unstable elements of a tonality to stable ones. The author of this article carries out mathematical analysis of this aspect within the multimedia genre, which combines sounds and silence, present in every piece of music, with visual imagery (motions, pictures, films, etc.). Its elements can be repeated, like sounds do, and, if they are central elements of the composition, they can be more stable than sounds. The author defines the common principles of functionality in multimedia and demonstrates the forms of their expression in a performance and in a happening. The analysis is based on the law of probability. It helps find regularities of stability-instability relationship in compositions containing a gesture. The author proves that in multimedia, where the length of a composition is often not defined by the composer, those elements are more stable, which are repeated with higher probability. The author is the first to give exact definitions to the regularities of functionality in multimedia, in which musicological analysis has usually been substituted with descriptions.
