Abstract：Rap music is the second most popular music style in the world. More and more Chinese people, especially the new generation, come to know the rap music and become fond of it. This form of art is created by the black, and some lexical characteristics such as omission, full of obscene language and rhyme are fully embodied in the lyrics. Since Black English spreads all over the world in the form of rap music, which is more and more popular and has an important influence on the Chinese, this paper intends to explore the typical expressions of Black English through rap music, and to make an analysis of the differences between formal English and Black English, such as words and phrases, spelling and pronunciation and so on. Moreover, as rap is closely and inseparably related to the culture life of the black, the relationship between Black English and the culture life of the black will also be involved.
