区别于中国传统的以讲演故事为主的说唱音乐（曲艺音乐），本文涉及的说唱音乐（rap music）是指起源于美国黑人聚集地的嘻哈说唱。在当代中文说唱中，成都方言说唱是发展较为繁荣的组成部分。本研究从成都方言特征对说唱的影响这一问题出发，选取7首方言说唱单曲（共计296个有效音乐小节）作为基础语料，从押韵和节奏两个方面进行语音韵律特征的分析。押韵方面，统计语料中各韵脚类型的出现规律，结合成都方言音系特征分析常用韵脚，并与普通话进行对比，阐述成都方言音系在说唱作词和语流（flow）编排中的优势。节奏方面，通过考察说唱音乐中的文本设置（text setting），统计音乐节拍强弱与歌词文本轻重的对应情况，探索音乐与语言节奏的关系。本文分析认为，成都方言的声韵母和声调特征相较于普通话而言更有利于说唱的歌词创作和演唱；成都方言说唱基本遵循音乐强拍与重读音节的对应约束，这一约束在音乐小节的最强拍位置具有最强的效力。此外，本文尝试将端木三（2016）提出的汉语重音规则应用到成都方言重音的标注上，并对该规则进行了一定的补充，总结了成都方言重音判定的方法。

Unlike the traditional Chinese rap music which is based on storytelling, the rap music referred to in this paper originated from the African American community in the United States. Among contemporary Chinese rap music, Chengdu dialect rap is one of the prosperous components. In this study, seven rap songs (296 valid music bars) were selected as the basic corpus to analyze the rhyme and rhythm of Chengdu dialect rap. In terms of rhyme, this paper counted the frequency of occurrence of different rhyme types in the corpus, analyzed the common rhymes in relation to the phonological features of Chengdu dialect, and compared with Mandarin to illustrate the advantages of the phonological system of Chengdu dialect in rap lyrics writing and flow arrangement. In terms of rhythm, the relationship between music and language, especially the correspondence between strong music beats and stressed syllables of the lyrics was explored by examining the text setting in Chengdu dialect rap music. The analysis in this paper suggests that the features of initials, finals and tone of Chengdu dialect are more conducive to lyrics writing and rap delivery than those of Mandarin; Chengdu dialect rap basically follows the correspondence constraint between strong beats and stressed syllables, and this constraint is most effective in the strongest beat position of a music bar. In addition, this paper has attempted to apply the Chinese stress rules proposed by Duanmu(2016) to the identification of stressed syllables in lyrics and make some supplements to the rules to summarize how to determine the position of stress in Chengdu dialect.
