Modelling Keys and Modulation with Scales and Harmonic Progressions
Résumé
Key changes, also called modulations, are common in tonal music. With cadences, they contribute to what can be called a tonal path, and generally to the structure of music. To better model key modulations throughout a piece, we propose to take into account scales, strong harmonic progressions as well as key relationships. We test these proposals on a corpus of Mozart String Quartets movements.
