Abstract

This paper examines the correlation between musical dissonance and auditory roughness-the most significant factor of psychoacoustic dissonance- and the contribution of the latter to algorithmic composition. We designed an empirical study to assess how auditory roughness correlates with human judgments of dissonance in natural musical stimuli on the sound object time scale. The results showed a statistically significant correlation between roughness and listeners' judgments of dissonance for quasi-harmonic sounds. This paper concludes by presenting two musical applications of auditory roughness in algorithmic composition, in particular to supervise the vertical recombination of sound objects in the software earGram.
