Your Brain On Freestyle Rap

by Moin Uddin Ahmed Tipu

Think what you will about rap music, but it does some amazing things to the mind. Anthony is joined by freestyle rap maverick Jelly D to demonstrate how even rap can be full of science.

MC Jelly D:

“A Peek Inside Rappers’ Brains Shows Roots Of Improvisation”

“Some rappers have an impressive ability to make up lyrics on the fly, in a style known as freestyle rap.”

“How Eminem Invents Freestyle Rhymes on the Spot”

“Freestyle rappers such as Eminem and Philadelphia’s Cassidy make up and bust out rhymes on the spot — a hugely challenging art form. Now, however, researchers have learned how the brain does it.”

DNews is a show about the science of everyday life. We post two new videos every day of the week.

Rape me in the face, that rapper was bad.

So many people dissing the dude freestyling. 1st of all, just because someone is a "rapper" doesn't make them a good freestyler, this applies to all rappers. 2ndly, off the top freestyling is fucking hard so stfu. Even though he didn't give a great rap interpretation of the facts given, at least his rap was somewhat understandable, most people choke before the 3rd rhyme so, yeah..

Hugh Cipher March 15, 2014 - 10:44 PM

DOPE science fact!! & thats coming from a veteran MC & amateur uber academic. For those dissing the mc I doubt they can rap because free styling is uber hard & free styling scientific jargon even harder. The host even explained the self censoring mechanism is turned off when free styling thus the control of your word flow is automatic also why I dont free style in certain situations becuase I end up pissing sum1 off ie: no filter

Yukim Nomoto March 24, 2014 - 7:37 AM

Thats why people say, "Knowledge is gangsta." Not money and chains. And yeah the dude was pretty bad, but he didn't choke so Im good with that. 

Thε Ålchεmïst March 24, 2014 - 9:13 AM

That beat was horrible.

Cugz Arui April 4, 2014 - 1:07 AM

im so practicing rap again

MrSevenstardust April 9, 2014 - 10:35 AM

His lack of flow and general skill has really boosted my own self-esteem.

Syilx01 April 12, 2014 - 9:03 AM

He was a pretty good rapper. Don't argue, its my opinion.

DreamSurf May 6, 2014 - 11:31 AM

I think the subject was quite overwhelming, it's not the same level of difficulty (I reason, I have no real experience in the matter) to Freestyle about "Gangsta stuff and yo mofos". He's freestyling a semi-technical subject about things he probably doesn't know about, related to science studies. 

 Freestyling contests tend to move around subjects that the rappers at least control, I bet you can be the best of the best but you'll probably fail if they throw at you a subject that's totally alien, like, you know, rap about these law articles that are pretty technical and require long rereads just to understand.

Liam May 18, 2014 - 2:31 AM

Wack. As. Fuck.

MilkOUSATCHE May 18, 2014 - 5:37 AM

Do you people realize this is freestyle, not pre-written?

Aly Rei May 18, 2014 - 9:00 AM

They're not testing enough people, there's way more to this. Some people fuse together freestyle rap and opera.

Mark McClenahan June 13, 2016 - 8:31 AM

Interesting topic, horrendous rapper haha. He can rhyme but has a pretty bad flow lmao..

Deep Sleep Melodies March 4, 2019 - 4:49 PM

callate pendeja😂😂

Michael Musson April 11, 2019 - 11:22 PM

He is not a bad rapper. He's pretty good, especially considering most rap is about the same subject matter, ad nauseum. It's just his personality that's cringey

Toge Inumaki July 1, 2019 - 10:24 AM

So this is why Sorcerers rhyme their spells 😎

Kojo November 26, 2019 - 3:49 AM

Top 10 rappers Eminem was afraid to diss.

so its all about self consciousness

Story Forest Distance Learning January 24, 2021 - 4:05 AM

Shame so many comments completely miss the point of this video. If you listen, it tells us that freestyling shuts off the part of the brain which makes us care about what other people think, allowing for creativity… Maybe he is not the best but it doesn’t matter, he is expanding his brain! It is these kind of comments bagging people for trying that prevent others from giving it a go! We are all in this together. Let’s pick each other up, instead of pulling each other down.

Zonex April 27, 2021 - 9:09 AM

I can freestyle better than him even tho I don’t practice

Jeremy Bazinaw December 14, 2021 - 4:33 PM

What the entire phuck is this
