On the introduction of musical knowledge, including the subjective ambiguity of a arranger, in the interactive harmonization system 'HASCAP'

摘要

The purpose of this paper is to propose a user interface using the expert system. This user interface is loaded in the interactive harmonization system. The user interface reflects the ambiguousness contained in the system and the user's subjectivity and taste in the technical work. Each membership function, which is defined by the control parameter specified by the user and based on seven pieces of technical musical knowledge, is used for this harmonization system. By changing the value of the control parameter according to the experimental music and examining the result, we find another natural accompaniment chord.
