Fuzzy Frequencies: Studying tonal structures by analysing pitch content extracted from audio

In this study, we explore the possibilities of pitch extraction from audio. Helena Cuesta’s recent multiple f0 estimator (2020) results in precise pitch analysis. We compare pitch class profiles derived from audio and symbolic encodings by analysing 492 compositions. In a close-reading study of Palestrina’s 8-mode Vergine cycle, we examine the effect of performance characteristics such as ensemble composition, acoustics, intonation, and performance practice on the quality of the profiles. Then, we zoom in on differences between the profiles of each mode. Finally, by analysing a selection of modal cycles we demonstrate to what extent pitch profiles can be used to analyse the historical development of tonal structure. We presented this work at the International Medieval and Renaissance Music Conference 2024 in Granada, Spain. For more details, please visit the conference schedule.
