Chapter 9 Conceptual Blending in Melodic Harmonisation: Development and Empirical Evaluation in the Case of the CHAMELEON System
- 411 Downloads
This chapter presents the CHAMELEON melodic harmonisation assistant that learns different aspects of harmony from expert-annotated data, blends learnt harmonies from different idioms using the COINVENT framework and harmonises user-given melodies. The learnt harmonic elements include chord types, chord transitions, cadences and bass voice leading, while blending is employed on the level of chord transitions. A methodology that integrates chord transition blending is utilised for constructing a compound chord transition probability matrix that combines information of two initial learnt harmonic idioms. This chapter also presents the key-findings of empirical studies on the perception of blends, focusing initially on results obtained from cadence blending and afterwards on the output of the CHAMELEON system. The empirical evaluation of the CHAMELEON system was performed through tests that were specifically designed for evaluating blending; results indicate that the COINVENT framework for conceptual blending is a promising tool for computational creativity in music.
