Is punk related to rock? What is the difference between them?

Many people are vague about these three concepts. Let me explain it to you with what I know.

Metal and punk belong to rock, and metal is divided into heavy metal and death metal. Punks are divided into hardcore punk, pre-punk, trendy, post-punk, etc. Let's talk about it in detail:

Black metal: anti-religious, good at using soprano, piano, violin and organ.

Death metal: hatred is the theme, emphasizing that there is no melody, the guitar is fast, the drum is fast, and the lead singer is unclear.

Destroy metal: the melody is slow, clean and occasionally hoarse.

Gorgeous metal: a branch of mainstream metal, which is popular in this area. Musicians wear colorful clothes.

Grindcore: No melody, only two or three minutes.

Garbage: alternative rock.

Hard core: from punk, rough lyrics and melody anxiety.

Heavy rock: lighter than metal.

Heavy metal: Electric guitar is distorted seriously, explosive and destructive.

Industrial metals: Computer simulates sound effects and imitates the effects of machines.

Neoclassical metal: there is a lot of infiltration of classical music.

Pop metal: adding pop elements to heavy metals is a big compromise of rock and roll.

Strong metal: a mixture of speed metal and whipping metal.

Avant-garde metal: the arrangement is complex and imaginative.

Speed metal: smooth melody, fast speed and clear articulation.

Whip metal: Come on, the guitar is granular.

Punk:

Hard-core punk: extreme, shouting and sloppy style has been unable to become the mainstream.

Pre-punk: advocating simplicity, low-key and cultural, and rough music.

New wave: Overpunk who likes to shoot mtv, laying the foundation for campus rock.

Post-punk: advocating destruction and reorganization, high technology and extremely complicated.

Alas, a branch of hardcore punk, pure violence.

Synthpop: playing with a synthesizer.

Power pop: About three minutes, rebellious and explosive.

No waves: atonal, harsh, artistic, no melody, unacceptable to ordinary people, but a paradise for musicians.

Punk revival: come on, beautiful melody.

Many people like to attribute punk to metal, which is still under discussion.

The first punk band in new york was theramones in London, which was represented by sexpistols. In the early 1990s, a group of punk revivalists-represented by greenday and rancid-emerged from the American underground music industry. These new forces brought punk music back to its original style and tried to add heavy metal elements to the music.

On behalf of rock band U2, Rolling Stones and Beatles, they are all very classic bands.
