Abstract

This paper investigates the impact of timbre on consonance perception. Through five large-scale behavioral studies (235,440 judgments), the authors demonstrate that timbral manipulations can reshape consonance preferences, even creating preferences for inharmonic intervals. Computational modeling reveals that these timbral effects dissociate psychoacoustic mechanisms, leading to an updated model incorporating harmonicity, roughness, and slow beats. The findings suggest perceptual origins for diverse scale systems and highlight the power of large-scale behavioral experiments in auditory perception research.
