基于动态规划的自适应和弦编配算法研究

Study on Adaptive Chord Allocation Algorithm based on Dynamic Programming

和弦的编配是作曲过程中耗时较长的一个重要步骤,传统作曲中的和弦编配主要采用人工完成,尚无成熟的自动和弦编配技术.本文针对以上问题,根据和弦构成规律与进行逻辑,提出了和弦体系构造函数(CFCS),设计出一种自动和弦编配的动态规划算法,以此来实现机器自动和弦编配.通过对多个算例进行实验,检测结果验证本算法是有效可行的.

The arrangement of chords is an important step in the process of composition,which takes quite a long time.In the traditional form of composition,the arrangement of chords was mainly manually completed,and there was not such technology as mature automatic chord arrangement.In view of the problems stated above,this paper proposes a CFCS according to the rules of chord arrangement and logic in operation,and designs a dynamic programming algorithm for automatic chord arrangement,so as to achieve the automatic chord arrangement done by machine.This algorithm is proved to be effective and feasible by experimenting with multiple examples.
