Rap is an element of Hip-Hop: Hip-Hop was founded in the poor working-class black culture of new york in the late 1970s and early 1980s. The word Hip-Hop consists of four elements: Rap (rhythmic speech), Break Dance (break dance performed by street boys), DJ (skills of playing records and singing discs), graffiti (graffiti art) and related costumes. The attitude towards life constitutes a complete Hip-Hop culture. Its BPM is about 90- 1 10 beat, and its Chinese translation is hip hop. Life before Hip-Hop was rap and a little r&; B, plus the sound effects of various grinding films, belongs to the music that young people love to play since the 1980 s, and the Hip-Hop in this period is called the old-school hip-hop New hip-hop appeared in the early 1990s and has been popular ever since. Different from the old hip-hop, this kind of hip-hop is characterized by faster rhythm and more complicated lyrics. The new hip-hop has entered today's international pop series because of the achievements of musicians such as Jay-Z, 2 Pac and the infamous B.I.G Recently, rap superstars will smith and Eminem made a big splash in major award ceremonies, which pushed this craze to a climax. When hip-hop was all the rage in the 1990s, many different styles sprouted in the new school era. Hip-Hop is not only a kind of music produced in urban slums, but also a kind of voice representing urban slums. Rap musicians began to describe the hard life of themselves or those around them. The word "hip-hop" is a new type of music. Since its appearance, it has not only represented a single music category. At the turn of the century in 2000, hip-hop has developed into a synonym for a new lifestyle, including music, clothing and behavior. Street dance literally means hip; Hop is a hop and Hip-Hop is a Hip-washing, so you can see its origin. Hip-Hop contains Rap and r &；; B The complicated rhythm and sound effects of the record player, as well as graffiti on the wall, are also extensions of hip-hop culture. Leisure and healthy parties, if hip-hop helps, it is easy to make friends. Followed by R &；; B R and b are rhythm and blues, rhythm and blues, rhythm and blues. It's a branch of Bruce. I think it is the result of the continuous development of jazz rhythm and blues music after World War II. On the basis of urban blues, it combines the characteristics of swing music and piano music Buji-Wuji, and its voice becomes more powerful, highlighting the rhythm of continuous progress. It also retains the tradition of improvisation of black music, and the ensemble still adopts the blues form of 12 bar and the repetitive harmony framework. Before World War II, Blues records were operated by small record companies. After the war, due to the change of black social status, several major record companies became interested in black music. At this time, the leaderboard began to replace the original "national record" with "rhythm and blues". The representatives of this period are louis jourdan (1908 ~ 1975) and Joe Leakins. The characteristics of rhythm and blues are directly reflected in many rock music, especially the early rock music, many of which are "cover versions" of rhythm and blues. In 1970s, the combination of rhythm and blues and gospel gradually accelerated its development. Therefore, all black music in the 1970s has a strong flavor of rhythm and blues, especially Sol's music (see Sol's music section for details) and rhythm and blues are sometimes almost indistinguishable (such as the works of marvin gaye and Jackson 5). After 1980s, R&B incorporated more pop music elements, making it more commercialized. For example, many rhythm blues have lost their original characteristics, and emphasizing the rhythm of backhand has become its main body. Sometimes, in singing, you can find a few blues notes brought out by sliding. In recent years, the music of so-called R&B singers Brandy&Monica and Brian Mcknight is no longer the real R&B. If we insist on theoretical analysis, we can only regard it as a commercialized R&B bleached by the pop music market. But not all R&B works are like this. For example, eric clapton's Change the World and Tracy Chapman's Give Me a Reason (17), two Grammy-winning works of 197, are all integrated with pop music. Rhythm and blues, as one of the important sources of rock music, has become a witness of history. After influencing rock music, its own continuous development also makes it one of the most popular music in the pop music world today.
