In 2008, researchers exploring two caves within the Swabian Jura mountains of Germany uncovered a handful of small, bone flutes. The finds have been at the least 35,000 years previous, making them the oldest recognized devices carved by Homo sapiens. Essentially the most full measured simply 8 inches lengthy and had been usual from the wing bone of a griffon vulture.
People, these and different discoveries appear to recommend, have been making music for longer than we’ve lived in cities or grown crops.
Digital musician, flutist and researcher Grace Leslie needs to know why.
She believes that music, from non secular hymns to Taylor Swift anthems, could contact one thing deep within the human mind—a hardwired want, maybe, to take a seat round a hearth or in a live performance enviornment and really feel related to the folks round us.
“Music is present in disparate cultures all world wide. It’s an innately human potential,” she mentioned. “And in most of these cultures, it’s used to attract folks collectively.”
Leslie joined CU Boulder this fall as an assistant professor within the ATLAS Institute and the School of Music. Her work melds artwork, engineering and neuroscience to probe the millennia-spanning relationship between people and an excellent tune, and whether or not the proper of music can assist to heal the physique and mind.
She’s additionally a performer who faucets into her personal physique to create music. In her flute live shows, Leslie typically comes onstage sporting a medical system known as an electroencephalogram (EEG) cap. The high-tech headgear transforms the rhythm of her brainwaves into hypnotic sounds that grow to be a part of her efficiency—the thoughts of the musician laid naked for an viewers.
“How can we use that potential of music to create closeness to develop new applied sciences that may enhance the connection between folks?” Leslie requested. “That’s the problem going through researchers.”
Talking motherese
It was that very same sense of connection that first drew Leslie to music.
She was born right into a musical household—her grandmother was a piano instructor, and he or she discovered to play when she was 4 years previous. In fifth grade, she picked up the flute. There was one thing totally different, she felt, about enjoying music in a band.
“The flute actually caught with me due to the social factor of it,” Leslie mentioned. “As a shy one that wasn’t athletic, it was a method for me to really feel like I used to be a part of a bunch.”

She isn’t alone in that feeling. In a 2021 research, Leslie and her colleagues performed music impressed by human heartbeats to individuals a collection of photos of individuals with totally different facial expressions: offended faces, unhappy faces and extra. Simply listening to these sounds modified how the themes considered the feelings on show within the photographs—an indication that music could, by some means, be inherently tied to human empathy.
Some scientists theorize that our moms could also be largely chargeable for this hyperlink. As the primary individual many people work together with in a significant method, moms talk with their infants by way of what researchers name “motherese”—a language constructed on lullabies, coos and even the pum-pum of the human coronary heart.
“It’s a musical language that moms sing to their infants, which is a method of speaking have an effect on to a baby that hasn’t discovered spoken language but,” Leslie mentioned. “That mother-infant bond is necessary to the survival of the human race.”
In a brand new undertaking funded by way of the U.S. Nationwide Science Basis, she’s getting down to uncover simply how highly effective that type of music might be. She’ll journey to neonatal care items, the place moms typically can’t talk with their infants. Leslie will look at whether or not piping in heartbeat-like music to infants and their moms can assist them expertise much less stress and perhaps even go away the hospital sooner.
“Is there one thing inherently therapeutic for ladies going by way of that have to have the ability to type that connection to their youngsters by way of music?” she requested.
As a primary step, Leslie plans to run related experiments on wholesome moms and infants in her lab on the CU Boulder campus this spring. Her work is a part of the School of Music’s new, interdisciplinary give attention to creating “common musicians”—or multiskilled, multifaceted artists who use music to interact with society.
Breaking obstacles
She additionally hasn’t stopped performing.
In 2015, Leslie launched a live performance collection known as Vessels drawing on the work of early pioneers in digital music similar to Pauline Oliveros, Alvin Lucier and Brian Eno.
In these performances, she turns to EEG expertise to, nearly actually, open up her mind for her listeners. EEG sensors, which docs use to diagnose epilepsy and mind injury, measure the miniscule blips of electrical energy that thrum contained in the mind on a regular basis. One sort of sample known as delta waves, for instance, rises to the floor when people fall quick asleep. When somebody is awake and energetic, beta waves grow to be extra widespread.
Leslie wears a cap onstage at her live shows, which information all of these waves, then feeds them into a pc program that converts the indicators into spare, sometimes-haunting sounds. On the identical time, she performs her flute reside, blowing into the instrument with gradual and managed breaths.
One viewers member in contrast the sonic expertise to resting in a heat tub. For the musician, it’s the final word train in vulnerability.
“Via listening to my physique and mind rhythms transformed into sound, I hope that the physique and mind rhythms of my viewers will start to entrain to my very own,” Leslie mentioned.
Leslie famous that she sees a parallel between her performances as a musician and her analysis as a scientist—on the stage and off, she hopes to faucet into music to interrupt down the obstacles that exist between folks.
“It’s very totally different as a performer to go on stage and have your precise state revealed to an viewers,” she mentioned. “If I get nervous and my coronary heart begins to beat, the entire concept is for the viewers to have the ability to hear that.”
