Designing Sound Representations For Musicology

This article describes the use of representations based on data extracted from the audio signal (sonogram, chromagram, audio descriptor) in musicology. A first part gives the historical context of these representations and discusses their transfer from the field of exact sciences to musicology. In the second part, I propose three new types of representation particularly effective in musical analysis: visualizations based on waveform and amplitude, a multilayered sonogram and chromagram, and an interface to assist the interpretation of self-similarity matrices for the analysis of musical forms and microstructures.
