Hip Hop-"You ain't gotta hold your tongue.”

The roots of hip hop are found in African-American music and ultimately African music. The griots of West Africa are a group of traveling singers and poets who are part of an oral tradition dating back hundreds of years. Their vocal style is similar to that of rappers. The African-American traditions of signifyin', the dozens, and jazz poetry are all descended from the griots. In addition, musical 'comedy' acts such as Rudy Ray Moore and Blowfly are considered by some to be the forefathers of rap.
Within New York City, griot-like performances of poetry and music by artists such as The Last Poets, Gil Scott-Heron and Jalal Mansur Nuriddin had a significant impact on the post-civil rights era culture of the 1960s and 1970s.
Hip hop arose during the 1970s when block parties became increasingly popular in New York City, especially in the Bronx, where African-American, Jamaican and Latino influences combined. Block parties incorporated DJs who played popular genres of music, especially funk and soul music. DJs, realizing its positive reception, began isolating the percussion breaks of popular songs. This technique was then common in Jamaican dub music and had spread to New York City via the substantial Jamaican immigrant community. A major proponent of the technique was the 'godfather' of hip hop, the Jamaican-born DJ Kool Herc, who emigrated to the United States from Jamaica in 1967. Dub music had become popular in Jamaica due to the influence of American sailors and rhythm & blues. Large sound systems were set up to accommodate poor Jamaicans who couldn't afford to buy records and dub developed at the sound systems. Because the New York audience did not particularly like dub or reggae, Herc quickly switched to using funk, soul and disco records. Because the percussive breaks were generally short, Herc and other DJs began extending them using an audio mixer and two records.
Turntablist techniques, such as beat mixing/matching, scratching and beat juggling eventually developed along with the breaks, creating a base that could be rapped over. These same techniques contributed to the popularization of remixes. Such looping, sampling and remixing of another's music, sometimes without the original artist's knowledge or consent, can be seen as an evolution of Jamaican dub music, and would become a hallmark of the hip hop style.
