The main difference between Black Metal and Death Metal is that the Black Metal is a Sub-genre of heavy metal music and Death Metal is a extreme subgenre of heavy metal music
Black metal is an extreme subgenre of heavy metal music. Common traits include fast tempos, a shrieking vocal style, heavily distorted guitars played with tremolo picking, raw (lo-fi) recording, unconventional song structures, and an emphasis on atmosphere. Artists often appear in corpse paint and adopt pseudonyms.
During the 1980s, several thrash metal and death metal bands formed a prototype for black metal. This so-called first wave included bands such as Venom, Bathory, Mercyful Fate, Hellhammer and Celtic Frost. A second wave arose in the early 1990s, spearheaded by Norwegian bands such as Mayhem, Darkthrone, Burzum, Immortal, Emperor, Satyricon and Gorgoroth. The early Norwegian black metal scene developed the style of their forebears into a distinct genre. Norwegian-inspired black metal scenes emerged throughout Europe and North America, although some other scenes developed their own styles independently. Some prominent Swedish bands spawned during this second wave, the second generation in Sweden being led by Dissection, Abruptum, Marduk, and Nifelheim.Initially a synonym for “Satanic metal”, black metal has often sparked controversy, due to the actions and ideologies associated with the genre. Many artists express extreme anti-Christian and misanthropic views, advocating various forms of Satanism or ethnic paganism. In the 1990s, members of the scene were responsible for a spate of church burnings and murders. There is also a small neo-Nazi movement within black metal, although it has been shunned by many prominent artists. Generally, black metal strives to remain an underground phenomenon.
Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted and low-tuned guitars, played with techniques such as palm muting and tremolo picking, deep growling vocals, aggressive, powerful drumming featuring double kick and blast beat techniques, minor keys or atonality, abrupt tempo, key, and time signature changes, and chromatic chord progressions. The lyrical themes of death metal may include slasher film-style violence, political conflict, religion, nature, philosophy, and science fiction.Building from the musical structure of thrash metal and early black metal, death metal emerged during the mid-1980s. Bands such as Venom, Celtic Frost, Slayer, and Kreator were important influences on the genre’s creation. Possessed, Death, Necrophagia, Obituary, Autopsy, and Morbid Angel are often considered pioneers of the genre. In the late 1980s and early 1990s, death metal gained more media attention as popular genre. Niche record labels like Combat, Earache, and Roadrunner began to sign death metal bands at a rapid rate.Since then, death metal has diversified, spawning several subgenres. Melodic death metal combines death metal elements with those of the new wave of British heavy metal. Technical death metal is a complex style, with uncommon time signatures, atypical rhythms, and unusual harmonies and melodies. Death-doom combines the deep growled vocals and double-kick drumming of death metal with the slow tempos and melancholic atmosphere of doom metal. Deathgrind, goregrind, and pornogrind mix the complexity of death metal with the intensity, speed, and brevity of grindcore. Deathcore combines death metal with metalcore traits. Death ‘n’ roll combines death metal’s growled vocals and highly distorted, detuned guitar riffs with elements of 1970s hard rock and heavy metal.
