随着各种行业的逐渐发展与壮大,音乐在其中的应用也越来越广泛,而它们对应用音乐的需求也在逐渐的扩增。因此,利用计算机自动生成音乐的问题就越来越受到关注。本文针对计算机在音乐自动生成中的问题,提出一种将音乐关系中的基本元素分开来进行建模、分析、生成、融合的分析方法。我们利用音乐节奏本身所具有的可以被形式化的特点,提出了一个概率上下文无关文法系统,其主要是用于描述相对独立的音乐节奏元素。该系统主要是对音乐作品进行学习与分析,并将音乐节奏转化为形式化的文学语句。通过内外概率算法是如何实现音乐节奏的自动生成的呢?本文将对其进行分析与探讨。
With the gradual development and growth of various industries, the application of music in them is also more and more widespread, and their demand for application of music is also gradually expanding. Therefore, the issue of using computers to automatically generate music is receiving increasing attention. In this paper, aiming at the problem of computer in music automatic generation, this paper presents a method to analyze, generate, and merge the basic elements of music relations separately. We use the characteristics of music rhythm itself can be formalized, put forward a probabilistic context-free grammar system, which is mainly used to describe relatively independent elements of rhythm music. The system is mainly for learning and analysis of musical works, and the rhythm of music into formal literary statements. How to realize the automatic generation of music rhythm through the internal and external probability algorithm? This article will analyze and discuss it.
