Tonal parsimony in chord-sequence analysis: combining modulation cost and tonal vocabulary
Researchers have developed a new method called tonal parsimony for analyzing chord sequences in music. This approach aims to reduce both the number of modulations and distinct tonal centers used in a piece, improving upon standard dynamic-programming techniques. Applied to a large dataset of chord sequences and annotated jazz standards, tonal parsimony significantly reduced tonal vocabulary and modulations while enhancing chord-scale agreement. AI
