针对目前自动作曲主要集中于西方音乐,研究中国音乐的自动创作模型。分别从音高和时值两个属性考察和分析民歌旋律特征,提出了基于旋律马尔可夫链的中国民歌自动作曲模式。选取具有典型民族特征的民歌进行分析,并给出了作曲程序实例和评价。实验结果表明,民歌马尔可夫作曲模式可以生成具有中国民族音乐特征的乐曲。该作曲模式可以作为专业音乐创作的一种辅助形式。
As the current automatic composition is mainly concentrated in western music, the paper focused on the study of Chinese music automatic creation model. Two properties of pitch and duration were chosen respectively to inspect and analyse the melody characteristics of folk songs. In this paper, an automatic composition model of Chinese folk songs based on melodic Markov chain was proposed. Some typical folk songs in Tibetan and Jiangsu areas were analyzed and two sample compositions were given for evaluation. Experimental results show that the composition based on melodic Markov model has the characteristic of Chinese folk songs. The composition mode can be used as an auxiliary form of professional music creation.
