Emo that has evolved just a tiny bit from talking about killing themselves, to bringing out their frustration with their parents and their small genitalia stolen from what used to be brutal lyrical themes from death metal.

Calling this shit "metal" and calling yourself a "metalhead" when you like any deathcore or deathcore influenced bands is completely wrong, and you are completely gay.
Go listen to real metal. Faggots.

My personal favorite genre of music, deathcore is a fusion of death metal and metalcore, used in deathcore: harsh vocals that can lead to pig squeals, palm muted guitar riffs, drums that sound like machine guns, and breakdowns.

A genre of music invented by scenesters to make them feel as though their metalcore bands are somehow related to death metal more then they already are. Metalcore as a genre is in fact derived from melodic death metal, especially that of Gothenburg Sweden. So in reality all deathcore is really just metalcore with a different name.

Deathcore is a genre of noise art created when a drummer plays to the monologues of throat cancer patient over the sounds of a pencil sharpener vibrating against the strings of an electric guitar. It is listened to by scenes kids along with metalcore, and some argue that deathcore is actually a subgenre of heavy metal. However, this cannot be true because heavy metal is a genre of music and deathcore does not technically constitute as music, for the only real instruments used is a set of drums and an electric guitar that is not actually played by a human being.

a term created by those that like to subcategorize as far as they can, when really, almost every single band dubbed as "deathcore" can be considered death metal. what makes the "genre" deathcore even more ridiculous, is that no bands will actually call themselves, nor admit to being deathcore, the "fans" and familiars are the ones that name it such. the only difference between what people consider death metal and deathcore is that "deathcore" focuses a little bit more on breakdowns, but old death metal bands such as Dying Fetus uses breakdown very much in their music, and are still called death metal.

a fusion genre consisting of AMERICAN-style death metal and/or Grindcore, and general metal-core influences. Deathcore is not as Swedish/European influenced as metalcore, but still features breakdowns, frequently ad nauseum. (The Gothenburg sound is not really death metal, but a different kind of thrash metal. it still rules, though.)

SIDE NOTE ON DEATH METAL:
actually a from of Thrash Metal, the European "Death Metal" sound tends to follow established rules of harmony. Harmonic minor modes are very common, and accidentals (notes falling outside the key signature) are kept to a minimum. it tends to be based somewhat on european Classical Music, but not as much as Yngwie Malmsteen. times signatures fluctuate far less than american DM.

American Death Metal follows NO rules of harmony and finding the song's key is frequently almost impossible. diminished and/or chromatic tonalitied fly about and disonance is a hallmark. blast beats are borrowed from hardcore/punk (metal an dpunk have a long history of cross-pollenization), and time signatures tend to fluctuate usually for a jarring effect. as in any genre, some bands are just barely able to play, but the really good ones are usually masters of their instruments.

the term itself doesnt exist- it was made up by a bunch of bored 13 year olds huffing on computer cleaner, and enough retards actually took it to be an actual genre. bands routinely ignore/disown the term.

By definition, deathcore is a hybrid of metalcore and death metal. Deathcore bands typically sound like deathgrind bands with a heavy influence from modern metalcore with frequently used staccato, syncopated open-note breakdowns and metalcore screams. A vocal technique used in deathcore frequently is the pig-squeal, which is also used in other grind genres yet with a distinctively different sound to the technique. Bands such as Job For A Cowboy and Suicide Silence laid out the blueprints for the genre and spawned many other copycat bands. The Red Chord and a few other bands also helped to popularize the genre. Like metalcore and nu-metal, deathcore bands have received heavy criticism for supposed trendiness, lack of skill, and/or differences from "real" heavy metal bands/genres causing many bands to change to a pure death metal sound (Job For A Cowboy/Annotations Of An Autopsy) or a purely metalcore sound (Bring Me The Horizon).

Deathcore is a style of extreme music often confused by its fans with death metal. Deathcore draws heavily from the "malcore" style of metalcore in the sense that elements of its sound, both in composition and production, are rejected by the more conservative metal culture (ex. death/black/thrash/sludge metal). Deathcore differs from metalcore in the sense that it is generally faster, more heavy, and tending toward darker themes such as are present in death metal. Deathcore is also notorious for the excessive use of breakdowns, an element also present (but less frequent) in death metal and other 'true' metal genres. Hardcore dancing, a dance style in which fans swing their arms and legs violently in rhythm, has become hugely popular among deathcore fans, and is a trademark of live deathcore shows.

Despite many fans' beliefs, deathcore is vastly different from traditional death metal. Musically, the deathcore song structure is generally much more formulaic than that of death metal; songs tend to have one or two guitar riffs, several breakdowns, and possibly a chorus. Deathcore composition is also much less complex, many songs featuring doubled guitar parts or simple guitar harmonies, with the bass guitar being almost entirely indistinguishable.

Possibly the biggest difference between the two genres lies in their production. Deathcore is produced similarly to metalcore in many ways. Clean guitar parts, extremely balanced guitar and vocal tracks, as well as heavily mastered drum tracks tend to cause deathcore and metalcore to sound much like popular hard rock music in terms of production.
