Analysis of psychoacoustic responses to digital music for enhancing autonomous creative systems

In the present article the authors describe a psycho-acoustics study aimed at obtaining data for the enhancement of creative systems. Specifically, it is provided an analysis of the emotional responses provoked by fractal-generated music, establishing the link between input parameters from which a given musical piece is generated, and the emotion provoked. This analysis constitutes the basis to elevate computer-assisted creativity: Our ultimate goal is to create musical pieces by retrieving the right set of parameters associated to a target emotion. This paper contains the description of (i) a method to evaluate the emotional responses to fractal-generated music fragments, (ii) acoustic settings and protocol, (iii) analysis of the emotional responses given by human listeners. Even though similar experiments whose intention is to elucidate emotional responses from music have been reported, this study stands because a connection is appointed between fractal-generated music and emotional responses, all with the purpose of advancing in computer-assisted creativity.
