Abstract
This paper describes an MUSAI (MUSical expression generation system by Adjective with Interaction) reflecting user's impression represented by an adjective, i.e., an image word. The MUSAI uses a Kansei space and fuzzy rules that represent a relationship between musical expression and impression. The inputted user's impression is mapped into a Kansei space and the parameter values of musical expression are obtained by fuzzy inference. Then, the musical expression is generated based on the obtained parameter values and the inputted MusicXML. If a user is not satisfied with generated musical expression, a user inputs a modification word with an adverb and an image word such as more bright, and the musical expression is modified by changing the coordinates values in a Kansei space. The validity of the MUSAI is confirmed by experiments. From the experimental results, it is found that the MUSAI successfully generates musical expressions reflecting each experiment participant's impression.
