Tonal parsimony in chord-sequence analysis: combining modulation cost and tonal vocabulary 事件

Tonal parsimony in chord-sequence analysis: combining modulation cost and tonal vocabulary arXiv:2606.03459v1 Announce Type: cross Abstract: We study the assignment of local tonalities to chord sequences, a task useful for harmonic analysis, composition, and jazz-oriented improvisation. Standard dynamic-programming approaches minimize modulations but can introduce unnecessarily many tonal centers. We compare this transition-only objective with pure minimum-vocabulary analysis and with tonal par
