Guitar playing vamp.
Miscellaneous facts about Jasper, courtesy of the Twilight Lexicon:
Jasper’s last name is Whitlock. He was human in Texas during the Civil War (his story will be told in detail in book three), so only Carlisle has been a vampire longer. He was twenty when he became a vampire (he was changed by a vampire named Maria). Alice’s nickname for him is "Jazz." He is 6′3" tall.
Rosalie is all about show; Emmett loves to make her happy–hence, lots of elaborate weddings. (When her history is public record, I think it will be more clear why she is the way she is.) Alice and Jasper aren’t into show, but they have the deeper relationship. They are married, but once was enough for them. Esme and Carlisle are also married, again, just the one time.
Emmett and Jasper have a hard time passing for younger than eighteen, but with their perfect credentials (birth certificates, driver’s licenses, etc.) people tend to accept whatever story they tell.
Jasper is very scholarly.
And from Wikipedia (spoilers galore):
Jasper Hale (born Jasper Whitlock) is the adopted son of Carlisle and Esme, adoptive brother of Edward, Emmett, and Rosalie, and husband of Alice. He was born in Texas and joined the Confederate States Army in 1861 to serve in the Civil War. Due to his extremely charismatic personality, he ascended through the ranks quickly. Jasper was turned into a vampire in 1863 by a vampire named Maria when he was 20 years old. As a vampire, he gained the ability to manipulate the emotions of those around him. Recognizing his high rank in the army, Maria decided to change him into a vampire to help her claim territory in Monterrey. Jasper's responsibility was to train young vampires and then kill them when they were no longer useful (about a year after their transformation- when their strength began to fade). After about a century of this, he grew weary of the lifestyle and joined an old friend, Peter, and his mate Charlotte. Jasper left the two eventually, not wanting to feed on humans because he could feel his prey's emotions as they died. Alice, foreseeing that they would be together, met him in a half-empty diner in Philadelphia, and together they sought out the Cullen family. Due to his past, where he was able to feed on humans whenever he chose, Jasper lacks strong self-control. However, in Eclipse it is suggested that the "vegetarian" lifestyle is not Jasper's first choice and that this also affects his self-control. He is described as tall with honey blond hair, and is muscular but lean. His body is covered with crescent-shaped scars, after the many years of fighting and training newborn vampires.
In Twilight, Jasper accompanies Alice and Bella when they are hiding from James. He uses his ability to calm Bella when she is stressed or afraid. In New Moon, he attacks Bella after she gets a paper cut, prompting the Cullen family to leave Forks to protect Bella. In Eclipse, Jasper teaches the werewolves and vampires fighting techniques to defend themselves against newborn vampires. In Breaking Dawn, Jasper leaves with Alice to find a vampire-human hybrid, and returns with her to defend Renesmee from the Volturi.

Personal history: Jasper served as a Major in the Confederate army during the Civil War. The vampire family that changed him in 1863 (TL) was very different from the Cullens in their dietary habits –they fed off humans. (PC2) Jasper became depressed over his way of life and sought something better. His search led him to Alice in 1948 (TL), which in turn led him to Carlisle in 1950. (TW14) (TL)
Jasper has the most difficult time with the lifestyle set by the Cullen family. He avoids contact with humans, as he is more tempted than the others to drink from them. Going to school is a difficult task, but he does it for Alice. (PC2)
He would do anything for Alice, as she is his whole life. Even though he treats the other members of his family with respect, he isn’t bound to them the way he is to Alice. (PC2)
Jasper uses the last name of Hale because he and Rosalie look so much alike and people assume them to be twins. The vampires tend to go with whatever the humans are willing to believe. Rosalie insists on using Hale as a last name, and therefore, Jasper took it as his, too. (PC3)
It was there, sitting in the lunchroom, trying to make conversation with seven curious strangers, that I first saw them.
They were sitting in the corner of the cafeteria, as far away from where I sat as possible in the long room. There were five of them. They weren't talking, and they weren't eating, though they each had a tray of untouched food in front of them. They weren't gawking at me, unlike most of the other students, so it was safe to stare at them without fear of meeting an excessively interested pair of eyes. But it was none of these things that caught, and held, my attention.
They didn't look anything alike. Of the three boys, one was big — muscled like a serious weight lifter, with dark, curly hair. Another was taller, leaner, but still muscular, and honey blond. The last was lanky, less bulky, with untidy, bronze-colored hair. He was more boyish than the others, who looked like they could be in college, or even teachers here rather than students.
The girls were opposites. The tall one was statuesque. She had a beautiful figure, the kind you saw on the cover of the Sports Illustrated swimsuit issue, the kind that made every girl around her take a hit on her self-esteem just by being in the same room. Her hair was golden, gently waving to the middle of her back. The short girl was pixielike, thin in the extreme, with small features. Her hair was a deep black, cropped short and pointing in every direction.
And yet, they were all exactly alike. Every one of them was chalky pale, the palest of all the students living in this sunless town. Paler than me, the albino. They all had very dark eyes despite the range in hair tones. They also had dark shadows under those eyes — purplish, bruiselike shadows. As if they were all suffering from a sleepless night, or almost done recovering from a broken nose. Though their noses, all their features, were straight, perfect, angular.
But all this is not why I couldn't look away.
I stared because their faces, so different, so similar, were all devastatingly, inhumanly beautiful. They were faces you never expected to see except perhaps on the airbrushed pages of a fashion magazine. Or painted by an old master as the face of an angel. It was hard to decide who was the most beautiful — maybe the perfect blond girl, or the bronze-haired boy.
They were all looking away — away from each other, away from the other students, away from anything in particular as far as I could tell. As I watched, the small girl rose with her tray — unopened soda, unbitten apple — and walked away with a quick, graceful lope that belonged on a runway. I watched, amazed at her lithe dancer's step, till she dumped her tray and glided through the back door, faster than I would have thought possible. My eyes darted back to the others, who sat unchanging.
"Who are they?" I asked the girl from my Spanish class, whose name I'd forgotten.
As she looked up to see who I meant — though already knowing, probably, from my tone — suddenly he looked at her, the thinner one, the boyish one, the youngest, perhaps. He looked at my neighbor for just a fraction of a second, and then his dark eyes flickered to mine.
He looked away quickly, more quickly than I could, though in a flush of embarrassment I dropped my eyes at once. In that brief flash of a glance, his face held nothing of interest — it was as if she had called his name, and he'd looked up in involuntary response, already having decided not to answer.
My neighbor giggled in embarrassment, looking at the table like I did.
"That's Edward and Emmett Cullen, and Rosalie and Jasper Hale. The one who left was Alice Cullen; they all live together with Dr. Cullen and his wife." She said this under her breath.
“Now you know the whole story,” I concluded. “So it’s your turn to talk. What happened while I was with my mom this weekend?” I knew Jacob would give me more details than Edward had. He wasn’t afraid of scaring me.
Jacob leaned forward, instantly animated. “So Embry and Quil and I were running patrol on Saturday night, just routine stuff, when out of nowhere — bam!” He threw his arms out, impersonating an explosion. “There it is — a fresh trail, not fifteen minutes old. Sam wanted us to wait for him, but I didn’t know you were gone, and I didn’t know if your bloodsuckers were keeping an eye on you or not. So we took off after her at full speed, but she’d crossed the treaty line before we caught up. We spread out along the line, hoping she’d cross back over. It was frustrating, let me tell you.” He wagged his head and his hair — growing out from the short crop he’d adopted when he’d joined the pack — flopped into his eyes. “We ended up too far south. The Cullens chased her back to our side just a few miles north of us. Would have been the perfect ambush if we’d known where to wait.”
He shook his head, grimacing now. “That’s when it got dicey. Sam and the others caught up to her before we did, but she was dancing right along the line, and the whole coven was right there on the other side. The big one, what’s-his-name —”
“Yeah, him. He made a lunge for her, but that redhead is fast! He flew right behind her and almost rammed into Paul. So, Paul . . . well, you know Paul.”
“Lost his focus. Can’t say that I blame him — the big bloodsucker was right on top of him. He sprang— hey, don’t give me that look. The vampire was on our land.”
I tried to compose my face so that he would go on. My nails were digging into my palms with the stress of the story, even though I knew it had turned out fine.
“Anyway, Paul missed, and the big one got back on his side. But by then the, er, well the, uh, blonde . . .” Jacob’s expression was a comical mix of disgust and unwilling admiration as he tried to come up with a word to describe Edward’s sister.
“Whatever. She got real territorial, so Sam and I fell back to get Paul’s flanks. Then their leader and the other blond male —”
“Carlisle and Jasper.”
He gave me an exasperated look. “You know I don’t really care. Anyway, so Carlisle spoke to Sam, trying to calm things down. Then it was weird, because everyone got really calm really fast. It was that other one you told me about, messing with our heads. But even though we knew what he was doing, we couldn’t not be calm.”
“Yeah, I know how it feels.”
“Really annoying, that’s how it feels. Only you can’t be annoyed until afterwards.” He shook his head angrily. “So Sam and the head vamp agreed that Victoria was the priority, and we started after her again. Carlisle gave us the line, so that we could follow the scent properly, but then she hit the cliffs just north of Makah country, right where the line hugs the coast for a few miles. She took off into the water again. The big one and the calm one wanted permission to cross the line to go after her, but of course we said no.”
“Good. I mean, you were being stupid, but I’m glad. Emmett’s never cautious enough. He could have gotten hurt.”
“I think I can live without school for a day. What are we doing?”
“I want to talk to Jasper.”
Jasper, again. It was strange. In the Cullen family, Jasper was always a little on the fringe, part of things but never the center of them. It was my unspoken assumption that he was only there for Alice. I had the sense that he would follow Alice anywhere, but that this lifestyle was not his first choice. The fact that he was less committed to it than the others was probably why he had more difficulty keeping it up.
At any rate, I’d never seen Edward feel dependent on Jasper. I wondered again what he’d meant about Jasper’s expertise. I really didn’t know much about Jasper’s history, just that he had come from somewhere in the south before Alice found him. For some reason, Edward had always shied away from any questions about his newest brother. And I’d always been too intimidated by the tall, blond vampire who looked like a brooding movie star to ask him outright.
“Alice, can I ask you a question? About the future?”
She was suddenly wary. “You know I don’t see everything.”
“It’s not that, exactly. But you do see my future, sometimes. Why is that, do you think, when nothing else works on me? Not what Jane can do, or Edward or Aro . . .” My sentence trailed off with my interest level. My curiosity on this point was fleeting, heavily overshadowed by more pressing emotions.
Alice, however, found the question very interesting. “Jasper, too, Bella — his talent works on your body just as well as it does on anyone else’s. That’s the difference, do you see it? Jasper’s abilities affect the body physically. He really does calm your system down, or excite it. It’s not an illusion. And I see visions of outcomes, not the reasons and thoughts behind the decisions that create them. It’s outside the mind, not an illusion, either; reality, or at least one version of it. But Jane and Edward and Aro and Demetri — they work inside the mind. Jane only creates an illusion of pain. She doesn’t really hurt your body, you only think you feel it. You see, Bella? You are safe inside your mind. No one can reach you there. It’s no wonder that Aro was so curious about your future abilities.”
