Musical Mode and Music Emotional Expression by Computer

摘要

This paper concentrates on the recognition of MIDI music's mode and music emotional expression base on mode by computer. First, we designed an algorithm which can automatically recognize the mode of a mid! music file. Then we carried out a raw data gathering experiment. After analyzing the raw data, we picked up a set of MIDI files as the training sample. Last, we put forward a method of classification of music emotion based on music mode by BP neural networks.
