An Emotion-Driven Musical Piece Generator for a Constructive Adaptive User Interface

This paper presents the results of recent modification in the Constructive Adaptive User Interface (CAUI) that induces a model of emotional impressions towards certain musical piece structures and improvises a piece based on the model. The CAUI previously employed a ready-made melody generating module with its internal workings abstracted from the CAUI. Utilizing such black-box modules, however, may impede further effort to enhance the CAUI. To address this problem, a replacement module that automatically creates tunes tailored to the listener's impressions has been incorporated. Current results indicate that the CAUI may induce relevant relations that can support the adaptive improvisation of impression-causing tunes of a musical piece.
