What's the difference between rock, punk and pop? Ask god for help

Rock and punk are not different, but tolerant. Punk belongs to a kind of rock music, which is a style of rock music. The counterpart of punk style is metal style. These are two mainstream styles in rock music. In addition, there are a few electronic and atmospheric styles, but they are basically born out of metal and punk. Punk was born in the mid-1970s. Punk music pays little attention to musical skills, tends to emancipate the mind, and is in sharp opposition to the mainstream position. Its biggest feature is "triad" (I can't say one or two sentences clearly, simply speaking, it is a simple repeated arrangement of several chords). Punk music generally pays more attention to the expression of ideas and social reality. Now most punk bands are not punk in the traditional sense. They pay more attention to the arrangement of music and concentrate on adding other elements to music. Metal has a longer history, and metal music is in sharp contrast with punk with a lot of gorgeous skills and beautiful melodies (this is the root of the fierce conflict between punk fans and metal fans). The arrangement of metals is usually very gorgeous and gorgeous, including the arrangement of dead metals and dark metals, which is not so "beautiful" and contains a lot of complicated techniques. Both styles can be called rock music, so rock music is a large range, and punk is just one of them.
