Rap is a vocal (口头的) style in which the performer speaks rhythmically and in rhyme, generally to a beat. The term of rap music is the same with hip-hop music typically-consisting of a rhythmic vocal style called rap. If we see it carefully, then we will definitely notice that the music usually is sung at higher pitches (调). Most of the time rap music is associated with chorus. Though rap music was primarily an American music style with African influence over its music and lyrics, recently it has been spread to almost the entire world. There is hardly any country or nation where rap music cannot be seen in some form or another, and it is one of the most popular music styles among the youngsters. However, when it comes to its history, it is believed that hip-hop or rap music started in the early 1970s，and gained much popularity throughout the world during the late 1970s and early 1980s. The history of rap music and hip-hop music is full of controversies (争议) and bans, as the lyrics sometimes relate to drugs and crime; even most famous pop stars and hip-hop musicians and singers were found to be associated with the controversies in their life. For that reason, no matter how popular this music style was or still is, it has always had a bad reputation in the eyes of mainstream society. 小题1:The passage is mainly about _____.
