Chapter 2: The Music Instinct [excerpts]

My first boyfriend after I quit the cello was a brooding drummer who test-drove his songs on street corners.

I followed him and his Gretsch kit to the grimiest bars in town, thrilling to the sound of his pulsing tom-toms and bass.

My punk ex-boyfriend’s Gretsch drum kit looked similar, but far less sparkly!

Although some of us have stronger musical skills than others, the myth of musical talent has been largely debunked.

As the neuroscientist Daniel Levitin, author of This Is Your Brain on Music, explains, there’s no such thing as a “music gene” or a “center in the brain that Stevie Wonder has that nobody else does.”

Like other animals, humans evolved in a world thrumming with sounds — whistling winds, cawing crows, chirping squirrels, burping frogs.

Steven Pinker enraged musicologists worldwide in his 1997 book How the Mind Works, dismissing music as nothing more than “auditory cheesecake.”

Music may be a sweet treat for the ear, but dismissing it as nothing more than “auditory cheesecake” ignores its inherent role in human evolution.

Gary Tomlinson, a musicologist at Yale University, traced the origins of music to a time before language, before human culture — before our ancestors could conceive of a distinct self.

The building blocks of music, he wrote, helped shape the modern brain.

In the video above, Yale musicologist Gary Tomlinson explores music’s evolutionary emergence, “and the connections of musicking to language, cognitive complexity, and the metaphysical imaginary.”

As I waded through Tomlinson’s dense academic text, my thoughts drifted towards my own origins.

Then something dawned on me: without music, I might not be here at all.

From left: My yogi-mathematician father and artist mother met in the mid-1960s through a shared love of music, in the sitting room of a boarding house in Toronto.

While expecting me, my parents lived in a one-room cabin in Carlsbad Springs, a rural area not far from Ottawa.

My parents owned just a handful of records in this cabin, where I came into the world during my older sister’s nap.

I was born — and likely conceived, my mother said — to the chiseled strains of Glenn Gould’s 1955 recording of Bach’s Goldberg Variations.

In an EEG study, researchers concluded that in humans, the ability to perceive a musical beat is “functional at birth.”

But when researchers adapted the EEG experiment on newborns in a study of rhesus macaques (a type of monkey native to Southeast Asia), they found no sign that macaque brains could detect a musical pulse.

Based on EEG experiments, the brains of rhesus macaques do not detect a musical beat the way human newborn brains do.

Snowball, the boogying cockatoo, was the first documented case of an untrained animal that could match a musical beat. (Snowball later hit the big time bopping to “The Piña Colada Song” in a TV ad for Taco Bell.)

Above (video): Snowball bops to the beat in the Taco Bell commercial.

In exchange for bites of herring, Ronan, a California sea lion, would bob her head up and down to the beat of a metronome and switch tempos on a dime.

Musical animals give hints that the neurological underpinnings of music might be older and more broadly shared than we ever imagined.

But somewhere down the line, human ancestors stumbled on ways to sharpen [our musicality] for reasons that chimps, our closest relatives, didn’t have.

Chimps and humans separated from our last common ancestor roughly six million years ago.

Music, like our species, has origins in East Africa.

Along the highway between the Serengeti grasslands and Tanzania’s Ngorongoro Crater — a meadowy oasis teeming with lions, zebras, elephants, and wildebeest — two colossal skulls of concrete mark the turnoff to the “Cradle of Humankind.”

In Tanzania, the turnoff to the “Cradle of Humankind” — Olduvai Gorge — features six-foot-tall concrete skulls of the hominid species Paranthropus robustus and Homo habilis.

The museum at Odulvai Gorge displays a replica of the Laetoli footprints discovered in 1978 by Mary Leakey.

Imprinted by feet hardly different from our own, the Laetoli trail proved that our ancestors walked upright, with a human-like stride, at least two million years before the massive growth spurt in the hominin brain.

In these footprints, Anton Killin, an evolutionary theorist, sees traces of rhythm.

But ancient neural connections leave no fossil record. They’re impossible to prove. Paleolithic tools offer more tangible clues.

Tomlinson, the Yale musicologist, believes the building blocks of music emerged from the rhythmic chipping of rock on rock. Homo erectus began chiseling diamond-shaped hand-axes about 1.7 million years ago.

Neurons that fire together, wire together. Thus, as our ancestors sharpened stones, tool-making sharpened the brain.

Next came fire. Homo erectus learned to harness flames at least 790,000 years ago, and possibly earlier.

Nourished by roasted tubers, hippopotamus, elephant, and boar, early brains doubled in size.

For Homo erectus, fire added leisure time.

Bored and restless around the primeval hearth, they might have bonded by synchronizing their voices and body movements, said [Anton] Killin, “rehearsing” precursors of song and dance.

Like a moth to a flame, my mother was drawn to music and adventure. Widowed at age twenty-six by my father’s death, Mom hitched a ride from Ottawa to Vancouver with two toddlers in tow.

Within weeks, she fell in with a band of ragtag musicians.

I was in diapers when she got cozy with the Pied Piper of the group, a tall and bushy-haired Californian named Michael Fles.

Though I have no memory of this time, as a toddler, I was surrounded by jamming musicians.

In Vancouver, Michael [Fles] worked the system, applying for a government grant to fund ‘spontaneous music workshops’ for children with special needs.

He got the idea from Christopher Tree, the musical wizard he’d followed to Woodstock the year before, in the summer of 1969.

Above: Trailer from the 2018 documentary “Christopher Tree” from Les Blank Films. Tree was a direct influence on the ‘spontaneous music’ scene my mother was part of in Vancouver. In the summer of ‘69, Tree opened each day of the Woodstock festival with a cacophony of Tibetan temple gongs.

Mom followed her musician friends to the mountains of Chiapas, where she tried her hand at Mayan-style pottery.

My mom, a widow in her late 20s, playing one of her clay flutes in Mexico. I was a toddler along for the ride.

My earliest memory is of a bonfire crackling in daylight as a long line of women carry earthen pots to the flames.

Mom said this memory fits a time when I was three, in the Mayan pottery village of Amatenango del Valle.

Gringos locos, they must have thought.

Meanwhile, back in Vancouver, two members of the “children’s spontaneous music workshops” regrouped in 1976 to launch Canada’s first training program in music therapy, at Capilano College (now Capilano University).

One of the founders, Nancy McMaster, said the program never strayed from the values of spontaneity and free expression rooted in “Woodstock, the ’60s, and some hitchhikers.”

Above: Music therapist Nancy McMaster in the documentary “Celebrating the Beginnings of the First Canadian Music Therapy Program” founded at Capilano University in 1976. This film features key members of the ‘spontaneous music group’ my mom was part of when I was a toddler.

The budding music therapists encouraged children with special needs, many of them nonverbal, to tune in to their own musical impulses moment to moment, and communicate in ways that transcended words.

While their approach was radical at the time, it was hardly counterintuitive. The earliest humans — also nonverbal — might have made music much like this.

Half a million years ago, in a balmy period in southern England, Homo heidelbergensis hunted rhinoceros and megaloceros (giant deer), leaving a cache of bones and stone tools at Boxgrove in West Sussex.

In southern England, human ancestors hunted megalocerus (giant deer) that stood roughly 6’7” at the shoulder and weighed more than half a ton. Reconstruction of extinct megalocerus at the Prehistoric Park in Tarascon, France. Photo Tylwyth Eldar, Creative Commons.

To divvy up the spoils and reinforce the chains of command without a brawl, the leaders would have hollered, pounded the ground, beaten their chests.

Anatomical changes helped them make themselves clear.

These hunters had lost the air sacs around the larynx that allow other primates to ‘hoot-pant’ without hyperventilating. Without these air sacs, the Boxgrove band could vocalize with close to human finesse.

During the last ice age, small bands of sapiens huddled in the caves of Germany’s Swabian Alps, playing flutes fashioned from mammoth ivory and vulture bone.

These flutes look like penny whistles, with finger holes carefully spaced to play tunes in five notes, similar to the pentatonic scales found in Scottish jigs or Javanese gamelan music.

Remarkably, our auditory cortex can rewire itself to process touch as well as sound. The renowned percussionist Evelyn Glennie, profoundly deaf since age twelve, often performs shoeless to allow her feet to feel the vibrations from the floor.

The human body, she told The Globe and Mail, is “like a huge ear.”

Most children can learn to hum in tune and dance to the beat, grinning all the while.

Anyone who doubts this can check out videos of preschoolers wiggling to music in Mexico, Cuba, or Senegal.

As a fledgling journalist, I struggled to pay the bills. Besides my freelance gig writing for a Reader’s Digest coffee-table book series, I cleaned houses and worked as an extra on film sets, wearing everything from zombie makeup to a torpedo bra for the role of a ’50s waitress.

Snapshots from my days as an extra on movie sets in mid-1990s Vancouver.

I was a “background performer” on shows ranging from The X-Files to Happy Gilmor (starring Adam Sandler).

If only I’d known sooner about the deep roots of music in my early life, and in the human brain. I might have had something to hold on to in my late twenties when I tried to reinvent myself as a cellist…

Wired for Music: The Visual Companion | Chapter 6: More Than Meets the Ear

A chapter-by-chapter series of images illustrating key ideas in my book Wired for Music. Click here to view the series from the start.

Chapter 6: More Than Meets the Ear [excerpts]

On a snowy day in January, when I was around ten, a couple of kids came to school after the holidays wearing a blue-and-silver metallic gadget.

Best friends got to try the foam-covered headphones. The rest of us stood and stared as they mouthed riffs from Billy Joel and Air Supply. Riffs no one else could hear.

The original Sony Walkman: Launched in 1979, this Japanese invention had an asteroid-like impact on how we listen to music.

This TPS-L2 model was the first portable music player without an external speaker. Before the Walkman, hardly anyone wore headphones (other than extreme audio geeks). Photo Binarysequence, Creative Commons.

“Everyone knows what headphones sound like today,” wrote the late Sony designer Yasuo Kuroki, “but at the time, you couldn’t even imagine it, and then suddenly Beethoven’s Fifth is hammering between your ears.”

Sony took this unique acoustic experience and made it mobile.

The novelist William Gibson, author of Neuromancer, bought his first Walkman in the summer of 1981.

As he roamed downtown Vancouver listening to Joy Division, he imagined a future where machines delivered data with the same “under-theskin intimacy” of the new music player.

A year later, Gibson named this virtual world “cyberspace.”

William Gibson’s award-winning novel Neuromancer (1984) follows a washed-up hacker who ventures into a futuristic world called “cyberspace,” which Gibson envisioned while wandering around Vancouver with his Walkman.

Years later, in a 1993 interview, Gibson declared: “The Sony Walkman has done more to change human perception than any virtual reality gadget.”

Up until the Walkman, noted the writer Matt Alt in The New Yorker, “music was primarily a shared experience.”

Then all of a sudden, the Walkman gave us permission to tune out.

“It’s like a drug,” said Susan Blond, a vice president at CBS Records, in a 1981 interview with the Washington Post. “You put the Walkman on and you blot out the rest of the world.”

Has listening on the fly given us a more intimate relationship to music — or simply a more distracted one?

Before the headphone era, no one could jog to Rihanna, let alone listen to a “pump song” just before a job interview.

One morning on Twitter, I spotted this thread: “What’s your favorite hype song?” Most of the comments mentioned high-energy tracks like Technotronic’s “Pump Up the Jam.”

But other picks showed a vulnerable side, such as “I Have Confidence” from The Sound of Music.

In a study from Northwestern University, college students who listened to an upbeat playlist opted to go first in a debate nearly twice as often as those assigned low-power tunes.

Hype songs had similar effects on other confident behaviors, the study found.

Michael Phelps, the most decorated Olympian of all time, never hit the pool for a race without listening to music “until the last possible moment,” he told The Guardian.

And in his memoir, A Promised Land, Barack Obama mentions drawing strength from music during his first presidential campaign.

“It was rap that got my head in the right place,” he wrote, especially Jay-Z’s “My 1st Song” and Eminem’s “Lose Yourself.”

For my own hype music, I might choose the Mahotella Queens, a South African trio whose a cappella harmonies and booty-shaking moves exude the message “nothing’s going to keep me down.”

Given the choice, though, I prefer my music live.

As Yo-Yo Ma pointed out in a USA Today interview, our largest organ is our skin:

When music moves molecules through the air, the cellist said, “You feel actually touched. It’s that tactile, it’s that personal — that intimate.”

But in recent years, I’ve been talking myself into a headphone habit.

Portable music, it turns out, can take exercise to the next level.

A 2020 review of 139 studies yielded key findings about music in exercise and sport:

Music makes exercise seem easier — reducing our perceived exertion by about 10 percent — and more enjoyable, distracting us from the voice inside screaming, “Make it stop!”

In lab experiments, sports psychologist Costas Karageorghis has shown that running in time to music helps regulate our stride patterns, reducing the micro-adjustments needed to maintain a steady pace.

Running in time to music gives athletes an edge — so much so that races including the Boston Marathon have either restricted or “strongly discouraged” the use of portable music players. Pictured: Marathon Rotterdam. Photo Peter van der Sluijs, Wikimedia Commons.

When we run or cycle in synchrony with music, he explained, our bodies use 6 to 7 percent less oxygen than they need to perform the same feat without moving in sync to a soundtrack.

Who could forget Olivia Newton-John singing “Let’s get physical”?

Workouts have come a long way since ’80s aerobics and Jazzercise, but there’s still no such thing as a silent spin class, let alone Zumba. GIF via Tenor.com.

After a race or workout, said Karageorghis, music should start at around ninety beats per minute and gradually bring you to a resting state with a tempo of sixty to seventy beats per minute.

In general, he added, “you have to think very carefully about the exact function that music is serving and select it accordingly so that it serves you well.”

Do the same rules apply to mental exertion?

Many people insist music primes them for peak performance in the cognitive realm. But is it true? Image Darekm135, Creative Commons.

In his book The Organized Mind, the neuroscientist Daniel Levitin breaks the bad news: Listening to tunes while we’re doing other things scatters our attention, making our brains work in a highly inefficient way.

And yet, Stephanie Land wrote her best-selling memoir Maid to a playlist that began with “The Mighty Rio Grande” by the American band This Will Destroy You.

Stephen King penned his horror blockbuster Misery to blasts of Anthrax and Metallica. And Jean-Michel Basquiat painted to Charlie Parker and Dizzy Gillespie. 

Could all these writers and artists be wrong?

After watching my mother painting in her studio to Franz Schubert and Erik Satie, I have a hunch that in creative fields, too much focus might interfere with the stream-of-consciousness thinking that inspires artists to do their best work.

Of course, this nebulous phenomenon would be tricky for scientists to study, and as far as I know, none has tried.

But there’s no doubt that listening to music alters core physiological systems in our bodies, not just our minds.

Listening to music can dampen the histamine response in people with food allergies after they’ve swallowed an allergen such as peanuts. But (warning!) this effect is unlikely to be strong enough to prevent a life-threatening reaction. Photo by PiccoloNamek, Creative Commons.

Concealed in our eyes, ears, mouth, and nose is a crucial antibody, Immunoglobulin A, our first line of defense against viruses and bacteria.

A meticulous review of sixty-three studies describes fluctuations of this antibody as “particularly responsive to music,” especially when people enjoy the sounds.

The immune boost may be mild and fleeting.

But even the most orthodox of medical professionals acknowledge that our mental and emotional states can influence how sick we become and how well we bounce back.

Music relieves pain by evoking a pleasure-reward response in the brain, which sends signals through the spinal cord instructing the body’s endogenous opioid system to suppress pain.

Music can help relieve pain after surgery.

According to a Queen’s University study, music works as a painkiller by evoking a pleasure-reward response that activates the body’s descending analgesia system.

Music can take the edge off insomnia as well.

However, insomniacs may need several weeks of nightly music before its sleep-inducing properties kick in, for reasons not fully understood.

If adding tunes to a bedtime routine was just a matter of conditioning — training our bodies that it’s time to sleep — then audiobooks at bedtime should offer similar results. But they don’t.

There might remain, noted Australian researchers, “mysterious effects of music that science has yet to address.”

Take the phenomenon known as “binaural beats.”

Often marketed as “soundwave therapy,” binaural beats deliver two steady tones at slightly different frequencies, one in each ear.

You’ll start to hear a low beat that sounds like it’s coming from inside your head. But this third sound is just an auditory illusion, the result of “wavelength interference.” Image by AdjwilleyCreative Commons.

On their own, binaural beats are about as tasty as cardboard, which might explain why they are typically sweetened with nature sounds and new-age music.

While more research is needed, in the few studies showing benefits from binaural beats, the music itself might be the special sauce.

But despite all my cello training, it was not until my late thirties that I fully grasped just how potent music could be.

My baby was born with a dimple in one cheek and a set of lungs that would soon produce blood-curdling screams.

He screamed in his stroller. He screamed on his play mat. He screamed in his car seat, baby swing, crib.

I tried every infant-soothing technique in the book — even even “cry it out.” Nothing worked. I became bone-achingly, brain-numbingly sleep-deprived.

Nine months in, on yet another bleary trudge through the city with my baby, a flyer on a lamppost caught my eye: African Movement Workshop. Something about the beaming drummer in the picture made me sign up on the spot.

Video: Click the "play" arrow and wait for mesmerizing marimba by Kurai Blessing Mubaiwa, the Zimbabwean musician I heard in a Vancouver workshop during my postpartum depression.

Partway through the workshop, the warm tones of a marimba rippled through the air. The gentle currents bobbed around me, mellow and cheery, and I had an almost physical sensation of being lifted by the exuberant melody.

After months of shouldering my baby, it was as if something was carrying me.

That day marked the turning point in my rough transition to motherhood. How could this be?

As a journalist, I was trained to question all things woo-woo, but I didn’t need a before-and-after brain scan to know something had shifted in me.

From that moment on, I vowed to stop underestimating what music could do.
