Introduction Harmonic Analysis Harmonic CCG Statistical Parsing Conclusion 2/24 Approaches to Musical Analysis • Varying goals: 1. model/aid compositional process 2. model listener’s cognition 3. suggest interpretations • Often not clearly defined

Introduction Harmonic Analysis Harmonic CCG Statistical Parsing Conclusion 3/24 Thesis • Tonal harmony has a syntax like that of language • Statistical parsing can be used to infer harmonic structure Contributions: • Formal grammar for syntax of harmony • Harmonic analysis by parsing • Practical statistical parsing of chord sequences • Extension to analysis of performance data
