Punk came out of the British economic crisis in the 1970s, which determined the rebellious nature of punk. In the 1970s, the declining United Kingdom faced an economic crisis. Crude oil prices soared and several major industries were in trouble. International trade has stagnated, prices have risen, and a large number of workers have lost their jobs. People are helpless in the face of the current situation and have been severely hit mentally. Therefore, teenagers have strong dissatisfaction and even despair about the real society. They angrily attack all aspects of society and express their thoughts through wild and cathartic behavior. Later, punk was introduced to the United States, and its scale in the United States was not large at first. Moreover, punk at this time was not a politically anarchic music, as it had been in Britain, but a language of teenage rebellion against their parents and the middle class they hated. Hip Hop is a cultural concept. It originated from the slums of New York in the United States in the 1970s, that is, the Brooklyn area where some poor black people lived. Because they lived in poverty, they often hang out on the street every day. Some people play basketball, some vent their emotions through graffiti, and some people put graffiti on the street. Dance to music and play Hip Hop. The so-called Hip Hop contains the following four elements─1. "Graffiti". 2. "Hip-hop". 3.『DJ』. It’s not enough for a good DJ to just be able to play songs. The most important thing is to know how to scratch records and be able to coordinate with the performance to arouse the emotions of the dancers. To be considered a good DJ. 4.『MC』. MC refers to Raper. An MC can use particles such as "oh", "yo" and "ah" to develop a unique rhythm and create a fanatical atmosphere in the crowd with just one mouth. Therefore, Hip Hop does not only refer to a music category, not just a dance type, but a whole set of cultural spirit, which mainly combines black language, music, dance, life attitude... etc., to form a complete picture of Hip Hop. Blues is the ancestor of jazz, rock and gospel songs. It was originally just a 12-bar musical form that was sung, sung or played by early black slaves in the United States to express their emotions. Blues music began in the Blue Department of the United States at the beginning of this century. . It was originally a short song shouted by poor black people while working, and it was also mixed with the rhythm and rhyme similar to the recital form in the church. This kind of music has an obvious special style, which is to use the "call and response" form similar to Chinese folk songs, which is called "Call and Response" in English. At first, the musical phrase will give people a feeling of tension, crying, and helplessness, and then the subsequent musical phrase will seem to comfort and relieve the suffering people. It’s like a suffering person crying to God, and then receiving God’s comfort and response! This improvisational playing method later slowly evolved into various types of music, such as Rock and Roll, Swing, Jazz... Therefore, blues is also the root of modern pop music. The harmonica has been widely used in blues music since about the mid-twenties. At that time, there were many street performers in the United States performing music. Their common instruments were banjos, drums, and something called "pan quill pipes" of wind instruments. Since the performance of the guitar and harmonica are better than these traditional instruments and are more suitable for performing in rough places, the harmonica is gradually used to play blues music. Around the 1930s, many black people moved to the big city of Chicago, and blues music and blues harmonica also spread in Chicago, and later became a genre of their own called Chicago Blues. When listening to blues music, you will find that they all seem to follow the same musical form. The reason is because a standard form of music commonly used in blues concerts is called 12 Bar Blues. R&B is the abbreviation of English Rhythm & Blues, translated as "Rhythm and Blues". As the name suggests, it adds a strong dance rhythm to blues. This music style was born in the 1940s. From an economic point of view, the rise of R&B is partly related to the consumption environment at that time. During World War II, the purchasing power of black people increased greatly, and the supply of black music exceeded the demand. R&B came into being and was invincible. The period from 1945 to 1960 was the heyday of R&B. At that time, black people were not allowed to enter white nightclubs, theaters and first-run movie theaters. Buying records and listening to them at home became their best pastime.

R&B has continued to develop, evolve, and grow since its birth, and has always been the mainstream element in the music world. R&B singers have always been undefeated on the pop charts, excluding B.B. King, Stevie Wonder, and others who have maintained their momentum for decades. In addition to the evergreen trees that have never fallen, the new generation of superstars who have emerged in the R&B music scene since the 1980s also continue the myth of R&B's dominance. It can be said that the 1990s was another unprecedented period of prosperity for R&B.
