Using Emotion Map System to Implement the Generative Chinese Style Music with Wu Xing Theory

Wu Xing is an ancient mysterious Chinese philosophy applied to many fields. The Music Emotion Classification (MEC) refers to the music cognition of mind with the categorized emotion result mapping to music parameters. Many researchers focused the topic on the MEC with theory and experiment development in the past decades. This chapter mainly discusses the possibility to synthesize the meta-level algorithmic music based on the analysis result from the previous research, with the proposed Emotion Map System (EMS) mapped into the innovated Wu Xing Emotion Map System (WXEMS), which indicates the emotion situation based on the X-Y coordinate movement in the WXEMS plane. The MEC result shown in the EMS/WXEMS trajectory controls the algorithmic music variation with the proposed mapping rules. In addition, the generative music varies smoothly according to the correspondent WXEMS data changed with any emotion transition, which can apply the technology into the generative background music in Chinese style using the proposed Wu Xing Automated Music System (WXAMS).
