Abstract
This article focuses on the methods of electroacoustic music analysis. An analytical algorithm of works is developed in the following way: 1) an analysis of records by a computer program; 2) a description of auditory experience; 3) a comparison of auditory and computer analysis. Electroacoustic work Mycenae Alpha by Iannis Xenakis was analyzed using this method. The work is considered in the context of the author’s compositional technique and technical capabilities of the computer UPIC on which the product was created. The connection of graphics with outside-time structure and of sound with inside-time structure was described, detailed analysis of the macro-composition was done.
