Unidades Semióticas Espaciais (USEs) e a manipulação artística sistemática do espaço extrínseco musical

Abstract

In this work we present the concept of extrinsic space and, based on bibliographic studies related to its syntactic and semantic development as well as the practice of spatialization in real time and composition of works for multichannel systems, we aim to structure what we call Spatial Semiotic Units (SSUs). Intended to be the smallest perceptible unit in the domain of extrinsic space capable of producing some artistic meaning, SSUs are a proposal of a toolkit for composing and analyzing both sound and image material. From a proposed orthography of SSUs, we present an analysis of the extrinsic space of an audiovisual electroacoustic music composition performed by the author. We evaluate the advantages and disadvantages of the procedure adopted at the conclusion.
