维基百科上的解释：
Rapping hip hop music can be traced back in many ways to its African roots. Centuries before the United States existed, the griots of West Africa were delivering stories rhythmically, over drums and sparse instrumentation. Because of the time that has passed since the griots of old, the connections between rap and the African griots are widely established, but not clear-cut. However, such connections have been acknowledged by rappers, modern day "griots", spoken word artists, mainstream news sources, and academics.
Blues music, rooted in the work songs and spirituals of slavery and influenced greatly by West African musical traditions, was first played by blacks (and some whites) in the Mississippi Delta region of the United States around the time of the Emancipation Proclamation. Grammy-winning blues musician/historian Elijah Wald and others have argued that the blues were being rapped as early as the 1920s. Wald went so far as to call hip hop "the living blues."

Jazz, developed from the blues and other African-American musical traditions, originated around the beginning of the 20th century. According to John Sobol, the jazz musician and poet who wrote Digitopia Blues, rap "bears a striking resemblance to the evolution of jazz both stylistically and formally."
During the mid-20th century, the musical culture of the Caribbean was constantly influenced by the concurrent changes in American music. From the 1950s through the 1970s, the descendants of Caribbean slaves in Jamaica were mixing their traditional folk music styles of mento music with the jazz, soul, rock and blues of America. In Jamaica, this influenced the creation of reggae music (and later dancehall). As early as 1956, deejays were toasting (an African tradition of "rapped out" tales of heroism) over dubbed Jamaican beats. It was called "rap", expanding the word's earlier meaning in the African-American community—"to discuss or debate informally."
Etymology [Rap这个词本身的来历]：
The use of the word to describe quick speech or repartee long predates the musical form,meaning originally "to hit". The word had been used in British English since the 16th century, and specifically meaning "to say" since the 18th. It was part of the African American dialect of English in the 1960s meaning "to converse", and very soon after that in its present usage as a term denoting the musical style.
Rapping can be delivered over a beat or without accompaniment. Stylistically, rap occupies a gray area among speech, prose, poetry, and song. Rap is derived from the griots (folk poets) of West Africa, and Jamaican-style toasting. It also has precedents in traditional Celtic music. Modern rap battles, for instance, bear a striking resemblance to the Limerick Game, a traditional Gaelic drinking game in which people compete for notoriety by making up insulting limericks about each other, the loser having to buy the next round of drinks. Likewise, puirt a beul, a form of Scottish mouth music was incorporated into Appalachian music and is an early ancestor of modern mouth percussion, or beatboxing. The influence of Scottish and Irish music on hip hop is not direct, since virtually all of the originators of hip hop culture were African American, but were transferred indirectly by way of American roots music.[citation needed] Roots music was created out of the fusion of African and Celtic music in the American South and is typified by the combination of African rhythms, Gaelic melodies, and (occasionally) vocal improvisation. It forms the basis of virtually all American musical styles from bluegrass to the blues, jazz, rock, funk, and country. Hip hop grew out of this same tradition; stripping down the melody, emphasizing the rhythm, and incorporating mouth music, battling, and vocal improvisation.
Rapping developed both inside and outside of hip hop culture, and began with the street parties thrown in the Bronx neighborhood of New York in the 70s by Jamaican expatriate Kool Herc and others. The parties introduced dancehall and the practice of having a "Master of Ceremonies," or MC, get up on stage with the DJ and shout encouragements to the crowd in a practice known as 'toasting'. Over time, those shouts of encouragement became longer and more complex and cross-pollinated with the spoken-word poetry scene to evolve into rap. It's believed that the first rapper to actually call himself an MC was Melle Mel from Grandmaster Flash and The Furious Five. He is also credited as being the first Hip Hop MC to rap in a traditional verse/chorus format. From the beginning hip hop culture has been syncretic, incorporating sounds and elements from radically divergent sources. While Funk breaks formed the backbone of early hip hop, Kraftwerk and other early techno artists were widely sampled as well.
