As an art, music is an indispensable part of human life. In all ages, music has always been a kind of special channel to express human emotion. So analysis for music emotion has become an important topic. Music emotion cognition model and interactive technology research is an important part of human-computer interaction, multimedia technology and computer music research. It belongs to the category of artificial emotion research, and is of great significance to promote digital media and digital entertainment product´s emotion interaction ability and promote the emotional human-computer interaction research. This paper is a multidisciplinary-cross research work of computer application, music aesthetics, artificial intelligence, cognitive psychology and so on.
