Grappolo 4, obra electroacústica del compositor chileno Jorge Martínez Ulloa. Un análisis acústico, psicoacústico, y espectromorfológico, en el estudio de procesos de estructuración hallados, y como aporte a estrategias de percepción acusmática

Abstract

A first reflection that allows us, as receivers and sound producers trained to develop from the sound that reaches our ears, and that is the product of the interaction with our acoustic-cultural environment, (which causes us to assume an attitude or position regarding this phenomenon), to ask ourselves about our ways of listening, is what could well allow us to make a preliminary, but necessary examination, of how to approach this electroacoustic piece. Indeed, the results obtained from this analysis, in which the study of the spectromorphology proposed by Denis Smalley was applied, will be presented, as well as considerations mainly of acoustic and psychoacoustic order that emerge from this application, which will as well offer an understanding of the nature of the structuring processes of the sound materials studied, and their articulation at the macro, meso, and micro levels, as an organizational strategy in sound perception.
