Death rock is reflected in the content of lyrics and has no limitations in musical form. No matter what instrument or genre you use, as long as the lyrics are related to life and death, it can be called death rock.

Deathcore is a branch of death rock. The music style is arranged along the hardcore grindcore route, and the lyrics are still related to life and death.

Death metal is also a branch of death rock. The style of music follows the metal route, and the lyrics are still related to life and death.

Through the above examples, death blues, death jazz, death folk and many other styles can become a type of death rock. Their main similarity is the lyrics content, while their differences are the performance style and musical form.

To put it simply, if you write a lyric related to death, you can express it in any musical form. If your music imitates deathcore or metal and your lyrics talk about "scrubbing," it's definitely not death rock.

There are too many categories of rock music, but if you understand clearly what is form and what is connotation. Then there are many new styles of rock music that are unknown or not yet popular.

In fact, it is not difficult to distinguish the form and connotation of music. The formal things are things related to music theory and performance, while the connotative things are mainly reflected in the lyrics and the attitude of the creator.

I repeat some old sayings. In fact, most of the styles of rock music are said by so-called music critics. And among music critics, how many of them know music and have played rock music? Many music critics in China know nothing about music, but they are good at English and have read and translated some foreign materials. You know, foreign music critics also have business guns... Many of today's rock styles are not created by creators, but are spoken by music critics...

Regarding rock style, it doesn't matter. What matters is whether you understand the music, whether you really like it, and whether you have your own principles for rock music.

The above is just my personal opinion and is for reference only. I believe you also have your own opinions.
