音高的算法生成与结构对应

Pitch Algorithmic Formation Corresponding to Structure

音高的发展问题一直是音乐发展中的核心内容之一。在算法作曲中,音高发展是以某种算法原理为规则,由音高生成以及音高控制(包括选择、组织、变化等等)两个部分共同完成的。作为底层原理的算法决定了所生成音高的结构形态以及可控方式与程度。本文将以算法作曲中三种常用的音高生成方式作为讨论对象,以Max/MSP软件作为操作平台搭建算法模块。通过实例分析,论述不同音高生成方式的特点,以及算法思维与音高结构的基本对应问题。

That the issue of pitch development is always one of the core contents of the music development.In the algorimic composition,the pitch development is based on a certain algorithmic principle as rule,and fulfilled with both of the pitch generation and pitch control（including selection,organization,and changes）.As an underlying principle,the algorithm determines the structure form of the pitch creation as well as its controllable method and extent.The paper explored three common modes of pitch generation,with Max/MSP as an operating platform to make algorithm modules.Through the case analysis,the author discusses the characteristics of different pitch generation,and the issue that the algorithmic thinking basic corresponding to the pitch structure.
