Finding Musical Pieces with a Similar Emotional Distribution throughout the Same Composition

Abstract

The aim of this work was to build a system that would enable to automatically compare various interpretations of the same composition in terms of the emotions, and to discover which of them are more and less similar. The stages of building such a computer system include such issues as annotating music data, building regressors, aligning different renditions, detecting and visualizing emotions over time, and result analysis. Analyzing the obtained results for Prelude No. 18 by Frédéric Chopin, the author found which performances of the same composition were more similar to each other and which were quite dissimilar in terms of the shaping of emotions over time.
