How did the guitar, bass and drum in the rock band evolve?

Violin and classical orchestral instruments are both embodied in rock music, but they do not occupy the mainstream position in rock music. Generally speaking, relatively few senior metal party rock fans can give you several such bands, and most of these "good and evil" arrangements and musical instruments are distributed in the huge branch of rock music-metal music. Melody metal, new metal, classical metal and opera metal are the main support points! You will also use some gorgeous metals and psychedelic metals, and even suicide black! But very few. Michael Jackson's music is also involved. How can I put it? It has something to do with the style of rock music. Let alone the spirit, it is noise! Rebellion, freedom, indulgence, single-handedly shouting anger and self-awareness expression are the main meanings of rock and roll. Violin is a classical or orchestral instrument, which does not have the characteristics of rock music. They are soft, elegant, lofty, serious and traditional, and can't be used. Even if it is used, it will not occupy the mainstream. They can only be "instrumental guest appearances", so rock music is rarely used because of their temperament. Tao is different. There is no common goal, so the appearance of metal music in rock music is accompanied by war, oppression and conflicts between nations and races. So the golden age of rock music is before, during or after the war. Among them, the strongest after World War II! Hippies have appeared in western countries, and even writers known as the "beat generation" have appeared in the literary world. People at that time, especially young people, were confused and impetuous. Among the representative works, Kerouac's Catcher on the Road or in the Rye, Osamu Dazai, a Japanese "rogue" writer, and even Haruki Murakami in the later period all have some "genetic sequelae". Many of these literary works are full of rock and roll, decadence, loneliness, sadness, anger, helplessness and smelly fart. From the 1950s to the mid-1980s, the rock era ended and gradually declined. Guitar, bass, drums, and an important keyboard (related to music style) are the main instruments because of noise! Their timbre wine exudes wildness, unruly, unruly and similar to the times! Guitar is a musical instrument with strong sexual suggestion, and its appearance directly created the birth of "bone skin".
