Research and Application of Man-machine Interaction Automatic Piano Accompaniment System Based on Artificial Intelligence Technology

In order to understand the research of man-machine interaction automatic piano accompaniment system, a research and application of man-machine interaction automatic piano accompaniment system under artificial intelligence technology is put forward. In this paper, firstly, the composition system based on the algorithm of Hidden Markov Model (HMM) is improved, and a man-machine interactive music accompaniment sound type selection method is proposed, which enables users without music knowledge to create kind and pleasing music. The principle and theoretical support of man-machine interactive creation are given systematically. Secondly, the feasibility of man-machine interactive system is proved by experiments. Finally, three professional composers were invited to systematically evaluate the improved accompaniment results, and it was concluded that the computer composition system could create music works that the public liked.
