Espectromorfologia e Processos de Estruturação

Abstract

Spectromorphology refers to the ways in which frequency spectra are shaped over time. Listeners’ responses to sounds and music derive from psychological responses to the energetic identity, behaviour and organisation of sound-types in the contexts of sounding structures. Instrumental archetypes are a useful initial reference base, from which a broader range of morphological models and combinations can be elaborated. This leads to a discussion of types of motion, which in the listening mind may be linked to real or imagined experience. Motion is expressed both through the goal-directed tendencies of external contours (evoking the notion of gesture) and through internal textural behaviours. The shaping and motion of spectromorphological archetypes provide models for defining structural functions and structuring processes: we interpret the significance of the combined actions of structural participants as we listen over shorter and longer stretches of time. Finally, the spatial aspects of spectromorphology and the influence of the listening environment are discussed.
