Metalcore and Deathcore are truly amazing genres of music. I'd like to start this article on telling you it's not just a guy screaming in a microphone and a bunch of other guys playing random shit on their instruments.
Metalcore began to rise in popularity in the 2000's, when bands like Killswitch Engage and Lamb of God stepped up. It introduced a new decade of music, which was heavy, and instead of singing, the vocalist "screams". Not all the vocals are screaming, often times theres a soft part in the song where the vocalist sings a chorus while the guitar takes a break from its heavy riffs to play some chords. "Screaming" isn't like yelling something, its a complicated thing to master. There's outward screaming (which is the harder and better sounding of the two), and there's inward screaming. It's pretty self-explanatory. Outward has you screaming as you're breathing out and inward is as you breathe in. Very few bands use inward, one famous one that i've already mentioned is Lamb of God. Some bands use it for what's called a "Pig Squeal" where the vocalist makes a sound that sounds like he's saying "Bree-Bree". You can find that in bands like Job For A Cowboy and We Butter the Bread with Butter. Most Metalcore bands you find will use outward, in which if you listen to the stuff I've already suggested, you'll understand the difference.
The drums in Metalcore and Deathcore are often difficult and involve alot of the bass drum. Most of the time, (I'd say all but I'm sure someone would name a band that doesn't), the drummer will use a double pedal bass drum, where the drummer can hit 16th, or even 32nd notes for those of great skill. To be a drummer of this kind of Genre, you need to know what you're doing, because unlike rock, there is no basic beat, you have to make up something fast and skillful to keep up with the rest of your band.
The guitar in these genres is insane. It introduces a new meaning to Distorted and Heavy, with often times drop-tuning (And no I didn't just say that tuning your guitar down makes your music heavier, because it doesn't). The riffs in many songs of this genre include alot of your E string (if you were in standard tuning, which most of this genre isn't), alot of palm-muting, often times tapping, hammer-ons, pull-offs, pitch squeals, tremelo picking, and alot of other skills not seen in every genre. My favorite skill would probably be the "Sweep". If you don't know what that is, look it up, there's many great articles for that skill on Ultimate-Guitar.com.
Now you're probably wondering what the "core" in Metalcore and Deathcore is. Well basically, it's the rhythm difference. If you listen to Deathmetal then you listen to Deathcore, the rhythm in each are very different. But most importantly, the difference is the BREAKDOWN. Yes, the breakdown. If you don't know what it is, prepare for your thought on this type of music to change. The breakdown was actually created out of Disco, believe it or not. This is where the drums back out for a moment and the guitar stops it's insane speedy riffs to play a mix of different patterns along with the drum's bass. a pattern like "Dun-Dun-Dun-Dun-Dun... Dun-Dun-Dun-Dun-Dun... Dun-Dun, Dun-Dun, Dun-Dun-Dun" would be a pretty basic breakdown. Often times they can be complicated and hard to play, and other times it can be basic and easy, but either way it's debatebly the best part of the song.
Now what the hell is the difference between "Metalcore" and "Deathcore". Well, not much. Deathcore is a amalgamation of Metalcore and Deathmetal. It follows alot of the same guidlines as Metalcore, such as the breakdown. But it's in most cases heavier, faster and the screaming is more obnoxious in my own opinion. Deathcore is on the rise nowadays, with Metalcore hanging on. Specifically in the last couple years it began it's sensation with bands like Suicide Silence, Whitechapel, Emmure, All Shall Perish, etc.
To finish this up I'm going to list some Metalcore and Deathcore bands that I think are amazing. Don't argue with me and say that one of the Bands I list aren't of these genres, because even if they aren't exactly Metalcore or Deathcore, they're pretty damn close! Those with stars by them are the more popular and mainstream ones that I would suggest people that are new to the genre take a look at.
