How does a freestyle rapper rhyme without rehearsal? How does a jazz improviser shape an instant solo? How do improv comedians wing it under pressure? Creativity is one of our most mysterious and fascinating capabilities, and astonishing things happen inside the brains of improvisers as they perform.
In this presentation we explore the science of improvisation, with rapper GoldLink, jazz pianist Jason Moran, and comedy duo Andy Bustillos and Alex Song of Upright Citizens Brigade. We’ll get inside the artists’ minds to see how their quick creative process allows them to step into the spotlight — without knowing what’s coming next.

What if you could silence your inner critic, that voice in your head that says “no” instead of “yes”? Improvisers can do this, and that’s one of the keys to their creativity.
We asked a rapper, a jazz pianist and a comedy duo to improvise for this story. All the performances you see were made up entirely on the spot.

[Rapping]: Nikes on my feet make my sight feel complete
I really, really, really like this Tom Misch beat
[In interview]: I try to start with a sentence or a word and then expand on the word. It’s almost like a meter, it’s like, “Five, four, three, two, one” and you’re like, “Uh, and a car!” and say something else. So I just try to start with a word and build upon the word.
[Rapping]: I’m so cool, they call me smooth. I’m real rude
I don’t understand what’s going on with me
I just want to get some money out of my dungarees

While other forms of creation — such as writing a novel or composing a symphony — can demand deep concentration, improvisation is a process of letting go. Musicians and other improvisers talk about stepping into an alternate reality, or entering a trance-like state, beyond thought. Distractions fall away; doubts disappear. Time seems to vanish.

GoldLink [rapping]: I’m the man, I’m the man, thought I told you that
I’m just trying to get some money out my quarter sack
[In interview]: It’s almost like you’re grabbing from a subconscious place, because you think — it’s like, what am I talking about? You can just talk about how you feel. You can talk about the mood. You probably say things you never thought you’d say.
[Rapping]: I had so much fun I didn’t want to come home
Now I’m back home I just want to go somewhere else
Somewhere else that’s just better
I don’t understand why I don’t have to wear a sweater
[In interview]: Nothing is stupid. You’re like I might try this and it might work and this might sound cool and everybody might like it. Then as well as like it might not, but you still would like be brave enough to try it.
[Rapping]: I just rolled around a beeper on its beep beep.
Um, this is really — this is really hard. [Laughs] Yeah. It’s fun though.
Freestyle rappers release themselves from mental constraints, so that self-editing doesn’t impede the flow of words. How is this possible? Neuroscientist Charles Limb and others have scanned rappers’ brains during a freestyle rap and during a memorized rap. The studies show that during freestyling, there’s a functional change in their neural networks. Through practice, the rappers have reorganized their brain activity, allowing their improvised lyrics to bypass many of the conscious-control portions of the brain, which regulate behavior.

[In interview]: In the moment, I couldn’t even say what was, what is happening. I recall playing an F sharp and using the kind of, the repetition of the note and then changing the octave and having it generate again and seeing then what it would make.

The science
Limb, of the University of California at San Francisco, studied the brains of jazz pianists by having them lie down inside an fMRI machine while playing a custom-designed keyboard. The fMRI produces brain scans that show changes in blood flow to different areas, illuminating which parts are more active than others during a given task.

The results of Charles Limb’s study showed that brain activity is organized differently while improvising. This happens mostly in the brain’s frontal lobes, which are essential regions for consciousness.
Here, in the prefrontal cortex, improvising fires up the self-expression areas and essentially turns off the self-monitoring areas, which judge and correct our behavior. These regions are also thought to be involved in focused attention and problem solving.
According to Limb’s study, this mental state may allow a looser, de-focused type of attention, sparking free associations and sudden insights.

Listening
Improv comedians know that creativity is an act of will and requires training. As Andy Bustillos and Alex Song of Upright Citizens Brigade show us, improvisers try to liberate their partner’s imagination by accepting every idea that’s offered. This can make them both seem fantastically attuned, even telepathic. It stems from careful listening and encouragement.

You know me, I’m hardcore.

Openness and trust
Once they know that all ideas will be accepted without judgment, improv comedians can play together without inhibitions. Their sketch becomes a back-and-forth game, and the audience gets swept up in watching people work so easily together, with enthusiasm and joy.

Persistence and commitment
If they feel they’ve stunk up the stage, improvisers know it’s important to do another show right away. One way to keep the creative juices flowing is what former improv comedian Stephen Colbert picked up from his Second City director: “Learn to love the bomb.” Embrace failure, because it’s going to happen. Then dive in again.
