Metalcore (also known as "metallic hardcore" or erroneously referred to as "screamo", names given to the more punk-influenced bands) is a combination of HeavyMetal, ThrashMetal and HardcorePunk, and sometimes takes a more melodic approach to the songs than thrash. It is characterised by gratuitous use of the MetalScream, as well as breakdowns. Lots and lots of breakdowns (although due to, ahem, certain bands, this attribute has been {{Flanderized}} a bit). If you're not in the know, a "breakdown" is when the music kind-of slows down to induce moshing or "throwing down"...or something like that. ([[https://www.youtube.com/watch?v=gEj2Z1yfWnI Illustrated]] with Music/{{Helmet}}'s cover of the
''Anime/{{Gigantor}}'' theme - the breakdowns are at 1:16 and 2:42.) Modern bands often tend to mix it up with clean vocals and melodic riffs (see Melodic metalcore below).

Metalcore began life as a blending between thrash metal and hardcore punk, and was used to describe bands such as [[Music/DirtyRottenImbeciles D.R.I.]], S.O.D., and Music/SuicidalTendencies in the 1980's, however the term changed its meaning in the 1990's to "metallic hardcore", and the genre metalcore originally defined became known as "crossover thrash". This newer "wave" of metalcore included bands such as Integrity, Earth Crisis and Converge. By the end of the nineties, metalcore had evolved into "melodic metalcore", which slowly grew in popularity until the mid-2000s, when it was a big mainstream draw. In fact, today, metalcore is the most commercially popular form of metal.

There are several common styles of metalcore. The original metalcore, often called "metallic hardcore" to avoid any confusion with modern metalcore, is simply hardcore with a prominent influence from metal (usually ThrashMetal or old school DeathMetal) and includes bands such as Integrity, Rorschach and Ringworm. Melodic metalcore (which includes bands like Killswitch Engage and God Forbid) fuses metalcore with MelodicDeathMetal influences and SopranoAndGravel vocal dynamics and is generally what most people think of when they think "metalcore". Holy Terror metalcore, meanwhile, refers to heavily ThrashMetal-influenced metalcore with occasional doomy tendencies and apocalyptic, biblical lyrical themes; the term was originally coined by Integrity and quickly became attached to Ringworm as well and is now a largely informal label to refer to anything with similar lyrical themes. Most of those bands inevitably sound like Integrity, Ringworm, or All Out War, though others (namely Disembodied) have earned the label from more of a lyrical standpoint than a sonic one. Finally, metalcore that contains too much hardcore to qualify as metalcore but enough metal to not entirely qualify as hardcore either (examples being Hatebreed, Terror, and later-era Madball) is occasionally (and derisively) referred to as "brocore" due to the stereotypes of the fans of said bands being dimwitted, thuggish meatheads who go to shows less to enjoy them and more to start fights.[[note]]This actually harks back to the original days of crossover, which tended to attract a troubling amount of thugs at shows who would go just to be as violent as possible in the pit. The same people would then show up at thrash metal shows and do much the same thing, often to the point of driving people away from those shows due to the very real possibility of getting severely injured in the pit thanks to them. It led to a fairly widespread backlash from hardcore, crossover, and thrash musicians alike, all of whom were quite pissed off at having their shows ruined by the aforementioned thugs, with hardcore musicians taking an especially strong dislike to it due to how it ran contrary to hardcore culture as it originally was.[[/note]]

When combined with DeathMetal, metalcore usually transforms into {{Deathcore}}, but the 2010s have also brought "Entombedcore" (a common colloquialism, but there is no definitive name for the sound at this point), which fuses the more metallic side of hardcore with Swedish death metal (NOT Gothenburg; the distinction is important) and crust punk (sometimes also powerviolence and/or black metal, depending on the band) to create an angry, dirty, and abrasive form of the genre that has gained a fair bit of popularity as of late; prominent practitioners include Trap Them, Nails, Xibalba, and All Pigs Must Die.[[note]]Trap Them actually existed as early as 2001 and could probably be considered an UrExample of the sound, but they didn't really grow famous until the late 2000s-early 2010s, which was around when Entombedcore started to become a thing.[[/note]] It should be noted that most of these bands are rarely called "metalcore" (mainly due to the term's negative connotations) and the bands are, for the most part, involved in the grindcore, crust punk, sludge and/or powerviolence scenes, rather than the modern metalcore scene. Similarly connected is "slamcore" (another colloquialism), which started to become a small but growing trend in the mid-10s; it is characterized by a mixture of slam death metal riffing and breakdowns with significant elements of beatdown hardcore. Notable acts in this movement include No Zodiac, Acranius, The Merciless Concept, and Dysentery (circa ''Fragments''); while it is strictly underground, it is starting to gain some traction in both death metal and hardcore circles and thus bears mentioning. It should also be noted that it is entirely separate from slammy deathcore and should therefore not be confused with acts like Ingested, Waking the Cadaver, or Signs of the Swarm.

The 2010s have also brought a new, or rather "[[{{Pun}} nu]]" variation called "Nu-metalcore" (also sometimes called "new nu metal"). As the title would suggest, it's a combination of {{nu metal}} and metalcore. Basically the base of the music is metalcore, while aspects of nu metal - which can range anywhere from rapping, downtuned riffs, turntables, angsty lyrics, and use of electronica - are added onto it. While mixing the two together is OlderThanTheyThink, it generally got it's footing in 2012 when Music/{{Issues}} released their debut EP ''Black Diamonds'', though Music/{{Emmure}} also integrated nu metal into their sound with ''Felony'' three years earlier. Others followed suit and started gaining attention, such as Of Mice & Men, Cane Hill, Attila, Stray From the Path, Dangerkids, Sylar and From Ashes to New. Reception to this has been mixed; some view it as a new innovation in the saturated field of the genre, while others are turned off by it because metalcore's popularity was attributed to people growing sick of nu metal. It's important to know that the genre is still emerging and as a result it is still mostly underground, which isn't helped by the negative connotations that both ends of the fusion hold with the metal community. That being said, it's influence has continued to grow and expand, with an increasing amount of bands with the style emerging. Like vanilla nu metal, many bands labeled nu-metalcore don't sound much like each other, because bands draw from a wide variety of varying influences depending on the band in question. Naturally this leads to {{Fan Nickname}}s such as "Linkin Park-core" and "Slipknot-core". This, combined with the fact that some fans are still repulsed by the label, makes classifying them tricky.

* Music/LoveAndDeath (Mixed with NuMetal)
* Music/MakeThemSuffer (later material, overlapping with {{Deathcore}}. Regarded by some as finding the line between the two genres)

[[folder:Bands confused for Metalcore]]
The following bands are often called metalcore, but are very much not metalcore. We keep this short list here because we don't want these bands put on the main metalcore list by an earnest passerby.
* Music/ThreeInchesOfBlood: The confusion comes from the dual vocalists and early tendency to tour with core acts. While switching between clean, punk styled vocals and harsh, growled and screamed vocals is common in metalcore, 3 Inches of Blood is very much a thrash-power metal band with little to no similarities to metalcore outside of common thrash elements. Furthermore, while one of their vocalists does use similar screams to some metalcore bands, their other vocalist uses a [[Music/JudasPriest Halfordesque]] screech that's far more in line with thrash metal, speed metal and PowerMetal.
* The Absence: They became a name around the same time as a lot of melodic metalcore acts and had some stylistic similarities on their first EP, but they quickly turned into straightforward thrashy melodic death metal.
* Austrian Death Machine: Straight ThrashMetal; they are often considered metalcore due to [[Music/AsILayDying who their singer is]].
* Battlecross: They have some minor stylistic similarities to some of the heavier melodic metalcore acts, but overall, they're thrashy melodic death metal.
* Music/BlackCrownInitiate: Progressive death metal. The confusion comes from their frequent usage of clean vocals and some djent elements (mostly in their earlier material).
* Music/TheBlackDahliaMurder: They qualified on their first demo and had noticeable elements of it on ''Miasma'' (''Unhallowed'' also had bits of it pop up from time to time, but not to any major degree), but they dropped any and all elements of it with ''Nocturnal'' in favor of aggressive, brutal death-tinged melodic death metal and never looked back.
* [=DevilDriver=]: Mixture of GrooveMetal and MelodicDeathMetal, along with some NuMetal on their self-titled. ''Pray for Villains'' was the closest that they ever actually came to melodic metalcore.
* Entheos: TechnicalDeathMetal with some djent and electronic elements.
* Music/FiveFingerDeathPunch: Straight-up GrooveMetal on their first album, [[ThrashMetal thrashier]] groove metal along the lines of Music/{{Pantera}}'s faster songs on the second, and a bit of both on the third. Some of their mellower songs border on PostGrunge.
* Gatecreeper: Like Mammoth Grinder, they're death metal with very prominent hardcore and crust elements, and they also tend to tour with punk acts. Also like Mammoth Grinder, they're still more death metal than hardcore, which is what separates them from similar acts like Black Breath and Outer Heaven.
* Music/{{Hacktivist}}: They're a mix of RapMetal, {{Djent}}, NuMetal, and [[HipHop Grime]]. They are sometimes considered metalcore (often lumped to the nu-metalcore trend) due to the SopranoAndGravel dynamics between the two lead rappers as well as the guitarist. Outside of that, they bare nothing in common with metalcore.
* Human Remains: ''Extremely'' influential to mathcore and also helped influence multiple early deathcore acts, but was very grindy TechnicalDeathMetal with some hardcore influence.
* Light This City: They mostly look like hardcore kids, and the other bands they've been in are mostly hardcore or pop punk, but the music is straight MelodicDeathMetal.
* Music/{{Marmozets}}: They are sometimes referred to as metalcore due to their use of screamed vocals contrasted by cleans. In reality, they're a heavier brand of alternative/indie rock with some progressive metal leanings. [[https://www.youtube.com/watch?v=717esXeCB-I They even mocked metalcore with a video of their own.]]
* Music/{{Mastodon}}: The confusion stems not from the music itself, but the timing. Their rise in popularity happened concurrently to the rise of melodic metalcore in the mid-'00s, and as such was often lumped into the scene. Musically however, they're a mix of [[DoomMetal sludge]][=/=][[GrooveMetal groove]] metal that later moved to a [[ProgressiveMetal progressive]][=/=][[AlternativeMetal alternative]] sound.
* Music/NeObliviscaris: Some might confuse them for this due to the SopranoAndGravel dynamics between Tim Charles and Xenoyr. That's where the similarities end. Their music is rooted in ProgressiveDeathMetal, with a [[NeoclassicalPunkZydecoRockabilly slew of other genres in the mix]]. Even in terms of vocals, Tim Charles' clean singing is far more operatic than that of a clean metalcore vocalist, and Xenoyr's is far more brutalizing than the average unclean one.
* Music/{{Neuraxis}}: The confusion mostly arises from their material having a mildly influenced Gothenburg sound combined with their old vocalist's style of harsh vocals and their tendency to tour with deathcore acts, but they are [[MelodicDeathMetal Melodic]] TechnicalDeathMetal.
* Pyrithion: Like Austrian Death Machine, they have occasionally been lumped in with metalcore due to Tim Lambesis. They're pretty straightforward death metal.
* Music/TheRedChord: They toured with a lot of metalcore acts back when they were getting famous and had a significant amount of pull with that fanbase, but they are deathcore/deathgrind. The only real stylistic similarities would be the occasional breakdown and Guy's vocals, but again, it was mostly just a mix of timing, the bills that they were usually on, and the fact that they were from Massachusetts.
* Music/{{Revocation}}: Back when they were first signed to Relapse Records, the metalcore label was thrown at them here and there due to Dave Davidson's somewhat shout-y vocal style and their occasional usage of vaguely Gothenburg-esque riffing, and they also tended to tour with a lot of metalcore, deathcore, and djent acts in their earlier days. They were always an amalgamation of melodic death, thrash, and tech-death, however, and they've moved more and more towards death metal with each album, while Dave's voice has grown progressively deeper and less shout-like.
* Soul Embraced: Possibly due to being a Christian band. They started out as a straight up death metal band, but their later albums brought ProgressiveMetal and AlternativeMetal influences into the fold.
* Sylosis: The confusion comes mainly from their vocalist's screaming style, as well as their time of emergence and their tendency to tour with melodic metalcore acts. Musically, however, the band is ThrashMetal with some elements of DeathMetal and ProgressiveMetal.
* We Are Harlot: Straight-up HardRock. They sometimes get this tag because of [[Music/AskingAlexandria who their lead singer is]].
* Woe of Tyrants: Some minor stylistic similarities plus a tendency to tour with core acts when they were active, but they were thrashy melodic death metal.

!!Tropes Common In Metalcore:
* ChristianRock: Metalcore and PostHardcore are both filled with Christian bands for whatever reason. Most famously are Music/TheDevilWearsPrada, Music/{{Underoath}}, Music/{{Demon Hunter}}, Music/AsILayDying, and August Burns Red.
** NotChristianRock: They also have a bunch of this
* {{Emo}}: Often associated with this genre, because bands like Atreyu, Bullet For My Valentine and early Avenged Sevenfold were often influenced by it.
* GatewaySeries: To extreme metal and HardcorePunk.
* GenrePopularizer: Issues did this with nu-metalcore. While combining metalcore with nu metal dates back decades, they were the first to prove that combining the two can be a successful formula with their debut EP ''Black Diamonds''. Not surprisingly, combining them has become increasingly common afterwards, with some pre-existing metalcore bands (Of Mice & Men, Emmure, Attila) even integrating it into their sound.
* HeavyMithril: Averted most of the time.
* LighterAndSofter: Often characterized as such to other Extreme Metal genres, thanks mainly to the PopPunk-oriented second wave of Melodic Metalcore that became the public face of the genre (and the main target of scorn from metal purists). Many of the more aggressive traditional metalcore groups are just as heavy, if not heavier, than most death or black metal. Take {{Converge}} for example.
* LongTitle: This was a pretty big trend in the genre for a while. Some of the worst offenders included Daughters, Norma Jean, Curl Up And Die, Shai Hulud, Botch, Coalesce, Integrity, Eighteen Visions and 7 Angels 7 Plagues. Candiria, Iwrestledabearonce and Burnt By The Sun were known to do this occasionally as well.
** Even Hatebreed got in on it with "Conceived Through An Act Of Violence", ''Satisfaction Is The Death Of Desire'', "A Lesson Lived Is A Lesson Learned", and a few tracks on their SelfTitledAlbum
* MohsScaleOfRockAndMetalHardness: Usually about an 8 or 9. Occasionally dip down to a 7 (Music/AllThatRemains does this sometimes) or very rarely go up to a 10 (Music/{{Chimaira}} and Music/TheDillingerEscapePlan, for example). Most mathcore and Entombedcore sometimes goes UpToEleven, but this is pretty uncommon.
* NeoclassicalPunkZydecoRockabilly: Most metalcore brings in alot of influences throughout the extreme metal scene, mainly MelodicDeathMetal, regular DeathMetal, BlackMetal, and ThrashMetal. Some bands bring in influences from PopPunk, ElectronicMusic, GrooveMetal, and AlternativeMetal.
** First-wave, meanwhile, often played with elements of noise rock, post-punk, free jazz, post-rock, grindcore, sludge metal, progressive rock, and whatever the hell else they felt like putting in.
** Later bands such as Music/{{Issues}} and Of Mice & Men have been combining this with NuMetal, which is known for being this trope. This has led to the nu-metalcore movement that's become popular in the '10s.
* PersonaNonGrata: A number of bands have been banned from venues due to overly-aggressive fans (The Acacia Strain were particularly infamous for this); the Borg Ward venue in Milwaukee made headlines on metal sites by banning ''the entire genre'' because of property damage from fans, and then proclaiming on social media that most other venues in the area won't book metalcore bands or tours for the same reason.
** Integrity became this in New York after arousing the ire of the mosh crew DMS. The reasons why [[RuleOfCautiousEditingJudgement Shall not be discussed]].
* ScaryMusicianHarmlessMusic: Commonly inverted. They usually dress like an average person or androgynously, but the music is still heavy metal.
* SopranoAndGravel: Most bands have this. This unfortunately causes people to assume any metal band that uses this dynamic is metalcore. Melodic Death Metal (and even regular death metal in some cases) are the usual victims of this.
* SurprisinglyGentleSong: Almost every band on this page will have at least one of these per album. The first-wave acts and bands that sound like them usually have something post-rock-influenced, while the melodic acts usually have a PowerBallad. Mostly averted by Entombedcore, but you'll still see more melodic songs here and there.
* TropeCodifier:
** Metallic hardcore: Integrity, Ringworm, or Earth Crisis.
** Mathcore: Music/{{Converge}} or Music/TheDillingerEscapePlan.
** Melodic metalcore: Music/KillswitchEngage, Music/ShadowsFall, Music/AllThatRemains, or Music/AsILayDying.
** Modern metalcore: Music/BringMeTheHorizon,[[note]]At least until ''[[NewSoundAlbum That's the Spirit]]''[[/note]] Music/AskingAlexandria, Music/TheDevilWearsPrada, or Music/ADayToRemember.
** Entombedcore: Music/TrapThem or Cursed.
** Nu-metalcore: Music/{{Issues}}, Music/{{Emmure}}, or Of Mice & Men
* UrExample: Either Integrity or Ringworm for the genre in general, Starkweather for mathcore, either Killswitch Engage or 7 Angels 7 Plagues for melodic metalcore, The Devil Wears Prada for electronicore (and arguably the current brand of breakdown-laden, post-hardcore-inflected melodic metalcore), either Trap Them or Cursed for entombedcore (''maybe'' also Racetraitor), and Biohazard for nu-metalcore (or Emmure and Issues for the modern version we know today).
* VocalTagTeam: A common trope due to the SopranoAndGravel dynamics. One is usually the screamer who serves as the primary vocalist, while other provides clean vocals (often in the chorus) for contrast. Though one-man variations exist.
* {{Wangst}}: Occasionally, especially common with emo-influenced bands. Nu-metalcore, being that it's a fusion of metalcore and the normally angsty nu metal, can fall into this.
