I just thought I'd clear that up after all of these "definitions" in which I have encountered an unbelievable amount of people who try to pass off their blatantly false pretenses as fact, and are slowly infecting others with their high-horse, holier-than-thou bullshit. Because honestly, with your ridiculous definitions, Beethoven, George Gershwin, and Britney Spears are/was "emo bands."
Now, onto the real definition.
In the early 90s there was a movement in the hardcore genre that came to be known as "Emotive Hardcore," spearheaded by Rites Of Spring. Harder-core-than-thou kids, who swore by Dischord Records a la Minor Threat, actually coined the term "Emo" as something of a put-down for the kids who really liked Rites Of Spring, Indian Summer and this new wave of "Emotive" Hardcore bands. That's right, "Emo" was once not something kids called themselves. The field exploded outwards from there - Level-Plane Records has always been the most famous Emo label. Acts like Yaphet Kotto, I Hate Myself, Saetia, Hot Cross, A Day In Black And White, Funeral Diner, I Would Set Myself On Fire For You, You And I, and hosts of others came in the next decade. Most emo bands have since broken up, but there's still the occasional hold-out (again, the majority of Level-Plane Records' roster has been a procession of emo acts). Like most DIY hardcore/punk of the time, a majority found its way onto vinyl and not much else. Some people consider bands like Fugazi, and later Sunny Day Real Estate, a progression of emo, but personally, I don't quite follow that philosophy.
Often, more recently, this gets intertwined with post-hardcore, and understandably so - that's nothing to make an issue of, since well shit, at least it's close.
Since the late 90s, though, bands have been emerging in the vein of Taking Back Sunday, Dashboard Confessional, and the thousands of their clones. As far as I can tell, some lazy journalist somewhere, writing an article about them, decided "Well, fuck, no one knows what emo is anyways, so I'll call these bands "emo" - sounds more appealing than bubblegum pop rock..." and the spiral continued downwards into the current amalgomation of bands MTV has told everyone is "emo."
Somehow, people decided that "emo" meant "emotional," which is obviously bullshit, as 99% of bands make music to illicit emotion, which would make "emotional" a completely all-encompassing genre from classical to opera to pop to rap.
Hope that helps.
Rites of Spring is emo.
NB: Emo does not mean the person cuts themselves, they might but that is not why they're emo.
2) A style. Quite similar from emo to emo but they try to make it quite unique. Some common features of emo's are:
-long hair that covers their eyes
-skinny fit jeans
NB: Not all emo's wear this style and just because you see someone who has one or more of the above features doesn't mean they're emo.
3) A genre of music. Some people find it depressing, but generally emo's listen to it because it describes something that has happened/happening to them perfectly. It's like the band has taken their memories and found the perfect way to describe it.
NB: Just because a band isn't very popular doesn't mean it is emo and some emo music is very cheery and consoling.
2) You see big groups of emo's in town wearing that style, but still managing to look cool and different.
3) Some people say My Chemical Romance is emo and depressing, but they have some cheeryish songs and their lyrics mean something to some emo's.
2. Type of music characterized by heartfelt, although sometimes whiny lyrics.
3. Person who listens to afformentioned type of music. Stereotypically wears too-small sweaters and tight jeans, black horn-rimmed glasses, and straight black hair, although this is not always true. Sometimes a vegan, sometimes straight edge.
What most people think it is, is someone that wears mostly dark clothing, guys that where eyeliner, and they all cut themselves.
What I have found it to actually be is people who might not have the hardest of lives, but just enough problems to make them think they do. They are not as sad as people think though, they only want other people to think they are. It is just the same as someone who over uses jokes because they have a low self esteem, except sad instead of glad. They might write poetry, where make up, skinny jeans, and stuff, but most "emo" guys are straight. And emo's who are not faking it do not like to be called emo. they are just whoever they are, without labels. the conception that they cut themselves is wrong. some do, but I've met a few preps who take out a razor, to. emo's are just as conforming as all the rest, and the real ones will admit it. they aren't trying to be abnormal, they just like how they look.
-real thing: no your not. your just a poser and your stupid.
Emo kids are mostly seen with acoustic guitars and My Chemical Romance attire, as well as black hair that simply screams "kick me in the balls as hard as you can".
High-pitch nasally voice can often be heard uttering the words "You just don't understand", followed by the sound of slamming door, then muffled whimpering as the individual proceeds to scratch their wrist, hoping you'll take notice of their weak and futile efforts to portray suicide and/or self-mutilation.
But most notably, Emos keep records of thier so-called "problems" in diaries. These records mostly include pointless whiny rants:
"They just don't understand"
"And Karen dumped me today. She says I'm the perfect guy, and that I'm always there for her, just like when her Chimichangas were too cold, and she ended up cutting her wrist out of shear depression. She says it's not me, it's her. She says I'm too good for her. I love her so much... I think I'll express my undying love for her by throwing my pillows and crying... and perhaps I'll write a love song and sing it off-key..."
