Sensory Dissonance: models, historical context and musical applications

In this seminar we present an algorithm for sensory dissonance modeling through a critical band filter, based on the work of William Sethares and John Pierce. We begin with a historical review of the term dissonance, aiming to define what we understood by sensory dissonance, followed by an explanation of proposed models, from Helmholtz to Vassilakis. We will also present a detailed study of a spectrum generated by the proposed algorithm, and evaluate the limitations imposed by it. At last, we will present musical examples of usage of these techniques for creative processes.
