Brain Scans of Rappers and Jazz Musicians Shed Light On Creativity

ananyo writes "Rappers making up rhymes on the fly while in a brain scanner have provided an insight into the creative process. Freestyle rapping — in which a performer improvises a song by stringing together unrehearsed lyrics — is a highly prized skill in hip hop. But instead of watching a performance in a club, Siyuan Liu and Allen Braun, neuroscientists at the U.S. National Institute on Deafness and Other Communication Disorders in Bethesda, Maryland, and their colleagues had 12 rappers freestyle in a functional magnetic resonance imaging (fMRI) machine. The artists also recited a set of memorized lyrics chosen by the researchers. By comparing the brain scans from rappers taken during freestyling to those taken during the rote recitation, they were able to see which areas of the brain are used during improvisation. The rappers showed lower activity in part of their frontal lobes called the dorsolateral prefrontal cortex during improvisation, and increased activity in another area, called the medial prefrontal cortex. The areas that were found to be 'deactivated' are associated with regulating other brain functions. The results echo an earlier study of jazz musicians. The findings also suggest an explanation for why new music might seem to the artist to be created of its own accord. With less involvement by the lateral prefrontal regions of the brain, the performance could seem to its creator to have 'occurred outside of conscious awareness,' the authors write in the paper." Bonus points for science rhymes; for anyone who has the time.

      Rap is purest crap, all real musicians agree
      Ignorance, its purest theme
      But at least it's not the effrontery
      Of boot and beery country

      Cappin' off dem white bitches
      Or leavin yur boots under the bed
      Neither scratches euphonic itches
      or creates harmony in your head

      country is purest dreck, all real musicians agree
      but at least it's not the annoyance
      of droopy pants boy bands
      and they don't shoot each other, you see

      Howlin' at the moon
      and stemmin the rose at night
      The one's got pants a-fallin off
      the other's jeans - too tight

      They both objectify wimmen, and pretend to be real men
      The's one's all drugs and bluster
      the other worships Custer
      and we know what happened to him

      But if it rhymes, it's all good
      one the one hand with a thump
      on the other with drippy harmony
      and the gayest cowboy rump

      So expose your kids to rock and roll,
      classical and jazz
      With any luck, they'll grow up,
      with music you won't razz.

      But should they fall, victim to,
      music you can't stand
      Be prepared, have earplugs ready,
      right there in your hand.

  3. Cue the hatred of hip hop artists by CRCulver · · Score: 3, Informative

    I'm sure this thread will have lots of blather about how hip hop lyrics are valid artistic expressions. I used to have the same prejudice, until I started studying epic poetry of Central Asia. Much of the Kyrgyz epic Manas, acclaimed by scholars in the West upon its discovery a century ago, is comparable to most hip hop artists: badly strung together recitations of how the hero has got lots of bling and bitches, and whoops the ass of his enemies.

      I'm sure this thread will have lots of blather about how hip hop lyrics are (not) valid artistic expressions.

      To support your argument that Hip Hop follows a long tradtion:

      LO, praise of the prowess of people-kings
      of spear-armed Danes, in days long sped,
      we have heard, and what honor the athelings won!
      Oft Scyld the Scefing from squadroned foes,
      from many a tribe, the mead-bench tore,
      awing the earls. Since erst he lay
      friendless, a foundling, fate repaid him:
      for he waxed under welkin, in wealth he throve,
      till before him the folk, both far and near,
      who house by the whale-path, heard his mandate,
      gave him gifts: a good king he!

      Beowulf (Prologue)

      or

      Yo! I know you heard of the Scyldings already
      When battle went down, the kings were deadly, swords steady
      Each one did whatever he said he
      Would do, and to grab onto more glory was ready.
      Scyld started their line, looked mighty fine
      Just a baby found a-bobbin' in a boat
      Grew great so kings gave him silver and gold

      "their"

      At least someone can explain to me why they like a certain hip hop song without a twenty minute discussion of music theory and jazz history.

      Did it ever occur to you that if you had a few years of musical education, such an explanation could be a short, concise event? There are terms and concepts that cover why one likes, or doesn't, jazz, classical, etc. They just don't boil down to "not 'nuff skanky hos" or "that shit don't rock my sub, man."

      Personally, if they completely cancelled football and actually taught music and music theory instead so people could create and/or appreciate music on more than a surface level when they heard it, I think we'd all be much better off. Certainly when I hear a "pop" music station, I think so. :/

      But... hey. Who am I to stand in the way of Little Billy's busted spleen? Rah. Rah. And stuff.

  4. Kyrgyz - is it like Chinese? by fyngyrz · · Score: 3, Insightful

    And is the translation any good?

    I speak and read Chinese, with a particular interest in classical characters. I've read, with considerable interest, the Tao te Ching in its near-original form, and also numerous English translations. I'm a martial artist, so such an expounding on "the way" is of great interest. I even suffered through a reading by Ursula Le Guin. Man, was that ever annoying. Then I had a few beers to try to forget. And I like her fiction. And I don't particularly like beer. Anyway...

    In the translations, in an attempt to make the content lyrical in English terms, and sometimes to rhyme, and sometimes to map to a particular agenda, the meaning is badly mangled — to be kind about it. The original can say something entirely mundane, and the translation gets all spiritual and freaky. It's enough to make me turn a little green sometimes.

    I wonder if these Kyrgz translations are more of the same.

    In the case of English and Chinese, the languages don't have anything even remotely resembling a 1:1 map once you get any further into them than "Ni hao", and even then... Someone probably, somewhere, might have told you Ni hao means hello... that's a very common start. What it actually means, though, is "you good" as an implied question that they do NOT expect you to answer... but if you go for "Ni hao ma" that's actually asking "you good?" whereas the first form doesn't indicate a need for an answer (compare to asking someone "how ya doin?", and they start telling you, while you groan to yourself "it was RHETORICAL, please SHUT UP!") It's not hello and it doesn't mean hello, it's just used where we would use hello. Ni hao maps a lot closer to an uninflected (non-questioning) "how ya doin" and ni hao ma to an inflected "how ya DOIN?." But you rarely get taught that, you sort of figure it out later. Well, some do.

    These mapping issues get much stronger as you get into any deeper meanings. In Chinese, that is. So... when I see translations of poetry and particularly when attempts are made to rhyme in another language... I get a little (more) cynical. :) Somehow I doubt that Kyrgyz ramblings make much sense at all in modern English, no matter what you do to 'em. That is to say, if you do enough to get them to make sense, they no longer map back to the original well.

    I can guarantee that's the case for English translations of the Tao te Ching. If you actually want to understand it, you've got a whole culture to learn, and THEN you've got to come to grips with centuries of change.
