Abstract

The present research project focuses on musical analysis using audio descriptors based on psychoacoustic models. This approach is justified in this context, because it proposes to study composers who have cultivated an approach with perceptive phenomena in their musical discourse, as in the case of Karlheinz Stockhausen and his conceptions of Points, Groups and Masses; György Ligeti and his idea of Timbre in Motion, and Iannis Xenakis and his Stochastic Music technique. We focus the questions of this project from a description of the historical context of the composers and the motivators of their musical discourse, starting by the serialism practice and the experience with electronic music. Our analytical hypothesis is that the interaction of compositional methods of the 50s and 60s with these questions leads to a creative interaction with the psychoacoustic phenomena. We will present our methodology in three stages. First, we will review the bibliography, in which we will focus on the writings of the composers studied here, as well as on the state of the art in the area of psychoacoustics and computational aided analysis. Second, we will execute an exploratory stage, mediated by the audio descriptors, in which, from the musicological surveys and computational tools, we will develop a methodology for describing musical works that dialogues with the musical context studied. Finally, we will perform a stage of musical analysis, in which the description methodology generated in the second stage will be applied in musical works and contextualized based on the particularity of each composer.
