"Narrator:" "Bobby mcferrin and neuroscientist daniel levitin" "Are our guides through a story in which age-old art" "And cutting-edge discovery intersect." "I think what ultimately it points to" "Is the relationship between humans and sound," "And the part of the brain that music goes to directly," "That's related to your -- to your deep emotions." "Levitin:" "The question that initially got me into the field" "Was where goose bumps come from." ""what's going on in my brain that's allowing" "This kind of thing to happen?""

"The rolling stones:" "¶ one, two ¶" "Why does music move us the way that it does?"

"When you talk about humans having a music instinct," "Which is really where we're going with this," "Where does that come from?" "People sometimes say," ""well, you're destroying the magic of music" "By studying it this way.""

"[ heart beating ]" "The fetus begins to hear between 17 and 19 weeks." "Already we are in a world of sound " "Of breath and heartbeat," "Of rhythm and vibration."

"To me as a physicist, sound is the actual wave," "The actual ripple of vibrating air." "The difference between one sound and another," "The difference between clapping hands" "And a having a beautiful tone," "Is the nature of the vibration." "It's the details of the vibration." "So, a musical note is a vibration that's very," "Very regular." "It repeats in a very orderly pattern." "So if you were looking at the air molecules," "You'd see a nice cyclical progression " "Compression, rarefaction, compression," "As it goes from me to you." "But if you just slap your hands together," "The vibration would have a kind of more chaotic feel to it."

"[ playing marimba ]" "The experience of music is something" "Deeply related to our physiology." "Woman:" "Music is energy." "It's possible to feel vibrations through the whole body," "And for me, this is a very crucial part of what I do."

"Glennie:" "For me, as a participator of sound" "And a creator of sound," "I hear." "I hear how I hear, but I hear," "And that's going to be different to how you hear." "Narrator:" "She feels the sound -- different rhythms," "Even different pitches -- through her feet," "Through different parts of her body." "Glennie:" "Obviously," "The low sounds we're going to feel" "In this lower part of our body." "There's such a big expanse." "The vibration is far, far open." "So you've really just got to almost be the bass drum" "When you play the bass drum." "You know that a very high sound like a cowbell" "Or a high rototom" "Or something like that isn't going to have" "The expanse of a big bass drum," "And so this is going to be felt in the upper part of your body." "So you can prepare yourself for that." "You really can." "My profession is about sound," "And I don't want to just use part of my body" "To experience that." "Sound is so much part of us." "Mcferrin:" "So, do you think that" "Our bodies are like a large ear when we're listening to music?" "I mean, does music -- can it get into your pores" "Like it does into your ears?" "I'm just fascinated by this." "Do our bones -- say, take, you know," "Different parts of our body, like bones." "They do." "Every object," "Be it a bone in your body, be it the earth," "Has a natural set of frequencies" "At which it wants to vibrate" "By virtue of how it's constructed," "How it's put together, what it's made of." "Every object has the capacity" "To vibrate in some manner." "You know, amazingly, we can write down equations" "For how things will vibrate if they're hit or plucked" "Or if air is forced by strings." "But there's no music in the equations." "Somehow those equations have to be animated." "Somewhere in there," "This gray thing inside of our head plays a role." "Narrator:" "The brain." "For most of us, the vibrations of sound waves" "Are relayed to the brain through the ear," "Which converts them to neural signals." "Levitin:" "As the sound hits the ear drum" "And it wiggles in and out, it sets up pressure waves" "Inside a snail-like structure called the cochlea." "The cochlea has hair cells lining it" "That are tuned to specific frequencies." "So at one end," "The hair cells only fire an electrical charge" "In response to low frequencies." "[ tuba plays ]" "At the other end, they fire an electrical charge" "In response to high frequencies," "And, of course, everything in between." "[ violin and tuba play ]" "Narrator:" "So the signal goes from the ear to the brain stem" "And up into the brain." "Levitin:" "And that electrical charge" "Goes to the auditory cortex," "Which is amazingly laid out in pitch order," "Almost like a piano keyboard." "The hair cells are wired to the auditory cortex" "In such a way that you've got low notes" "Stimulating this part of the auditory cortex" "On up to high notes stimulating this part." "We used to think that there was a music center in the brain." "We don't think that anymore." "There are music centers," "And they're spread all over the brain." "[ orchestra plays ]" "Narrator:" "The auditory cortex activates" "As it receives signals from the brain stem" "Through the inferior colliculus" "And the medial geniculate nucleus." "Levitin:" "If you could look at all the different" "Areas of the brain involved in extracting" "The signal from sound to turn it into music," "You'd see a bunch of coordinated" "And a bunch of uncoordinated firing" "In different parts of the brain," "Kind of like a neural symphony, a neural orchestra."

"It's very " " I'm very literally touching you," "And when you speak to me, you are literally touching me." "And when we extend that principle" "To the sound of a violin..." "You know, it's not so much the sound of the violin." "It's the silence thereafter." "That's the moment when, in some ways," "You hear what was just said." "Man:" "Sound is a very strange phenomenon." "What is it?" "It doesn't live in our world." "What we played or heard" "Ten seconds ago in this room is gone." "And this, I think," "Is what gives music its really tragic element" "Of the fact that it can die, of the fact" "That it is a lifetime." "Every note is a lifetime for itself." "And there is an element of penetration through the ear" "Which gives sound -- and, in the end, of course, music " "The great power that it can have."

"So, first, I'm going to put these on your fingers," "And we're going to be able" "To monitor your galvanic skin response " "Basically, how much you sweat " "And I'm going to clip this to your ear," "And this will get your pulse."

"[ dramatic soundtrack plays ]" "You see the scary music" "Makes the skin response jump way up." "It's part of the fight-or-flight mechanism." "The scary music, we think, is kind of a metaphor." "It's metaphorically invoking something" "That would cause you to have to run" "Or to freeze or to fight, and it causes your body," "Even unconsciously, to prepare for that." "You sweat more, your stomach muscles constrict," "Your pulse increases, your heart rate increases." "This really shows that our bodies" "Are very finely tuned to respond to music," "That it's unconscious" "And that we're doing it without any" "Volition or control over it."

"They create certain reactions in our brains." "[ singing ]" "Mcferrin:" "So this brings up an interesting question, then." "Does that mean that the neurons or whatever" "Is working in your brain becomes accustomed" "To hearing something in a certain context " "Yes." "Or are they developed that way?" "They're free in the beginning, right?" "They're free in the beginning." "And then, as -- over time," "When you hear a particular kind of music" "With a structure, then the neurons are fused" "In a certain way to accept this music in a " "The brain starts out" "With millions and millions of neurons" "That don't know what to do," "And they're shaped by experience." "And the process of maturatn in the human child" "Is a process of hooking those neurons up" "Into neural circuits, neural networks." "We're all born with a music module" "That allows us to learn the rules" "Of whatever music we're exposed to." "As another element," "Just covering the elements of music, tempo," "We associate fast tempo with..." "Energy, spiritedness..." "Slow tempo with..." "Funeral marches." "So when someone'sad, you know," "Their body is sort of hunched over" "And they're moving slow," "And when they're happy, they're full of energy," "And the slow movement leads not only to a slow tempo," "But also stepwise motion in the melody" "And falling contours."

"I often work to music." "When you're trying to do serious writing," "I've found some pieces of music had really " "Pretty big impact." "And I began to think that through that music," "I can engage with my evolutionary past" "Almost as much as I could by looking at fossils" "And stone artifacts."
