3/13/2023 0 Comments Definition of sonority in music![]() The opposition between consonance and dissonance underlies much of Western music (e.g., Dahlhaus, 1990 Hindemith, 1945 Parncutt & Hair, 2011 Rameau, 1722 Schoenberg, 1978). ![]() Consonant tone combinations tend to be perceived as pleasant, stable, and positively valenced dissonant combinations tend conversely to be perceived as unpleasant, unstable, and negatively valenced. Simultaneous consonance is a salient perceptual phenomenon that arises from simultaneously sounding musical tones. We hope that this package will facilitate further psychological and musicological research into simultaneous consonance. We formalize this conclusion with a computational model that predicts a musical chord’s simultaneous consonance from these three features, and release this model in an open-source R package, incon, alongside 15 other computational models also evaluated in this paper. We conclude that simultaneous consonance is a composite phenomenon that derives in large part from three phenomena: interference, periodicity/harmonicity, and cultural familiarity. ![]() Here we question this view, substantiating our argument by critically reviewing historic consonance research from a broad variety of disciplines, reanalyzing consonance perception data from 4 previous behavioral studies representing more than 500 participants, and modeling three Western musical corpora representing more than 100,000 compositions. Various competing theories of consonance have been proposed over the centuries, but recently a consensus has developed that simultaneous consonance is primarily driven by harmonicity perception. Simultaneous consonance is a salient perceptual phenomenon corresponding to the perceived pleasantness of simultaneously sounding musical tones.
