针对基于隐马尔科夫模型(HMM)的算法而实现的作曲系统进行改进,提出了利用人机交互式的音乐伴奏音型选择方式,实现了使不具备音乐知识的使用者也可以创作出善心悦目的乐曲。系统的给出了人机交互式创作的原理以及理论支持,通过实验证明了人机交互系统的可行性。最后邀请了三位专业作曲家对改进后的伴奏结果进行了系统评估,评估认为,计算机作曲系统可以创作出大众喜欢的音乐作品。Most of the existed composing Systems need the help of professional composing knowledge in the composing progress.While this paper proposed a new method,which is mainly to design a human-computer interaction between the ordinary people who command little knowledge about composing and the HMM based harmonizing system.With the improved harmonizing system,one ordinary people can compose a brilliant accompaniment for the given melody.Experiment shows that the proposed method is feasible to harmonize a melody.In the end,three professional composers are invited to evaluate the harmonizing results generated by the improved system.The evaluation shows that the improved system is able to generate favorable music for the common people
