Talking Music and Science with Yo-Yo Ma

Posted on by

It’s not every day that an amateur guitar picker gets to play a duet with an internationally renowned classical cellist. But that was my thrill this week as I joined Yo-Yo Ma in a creative interpretation of the traditional song, “How Can I Keep from Singing?” Our short jam session capped off Mr. Ma’s appearance as this year’s J. Edward Rall Cultural Lecture.

The event, which counts The Dalai Lama, Maya Angelou, and Atul Gawande among its distinguished alumni, this year took the form of a conversation on the intersection of music and science—and earned a standing ovation from a packed house of researchers, patients, and staff here on the National Institutes of Health (NIH) campus in Bethesda, MD.


Sound Advice: High School Music Training Sharpens Language Skills

Posted on by

Band InstrumentsWhen children enter the first grade, their brains are primed for learning experiences, significantly more so, in fact, than adult brains. For instance, scientists have documented that musical training during grade school produces a signature set of benefits for the brain and for behavior—benefits that can last a lifetime, whether or not people continue to play music.

Now, researchers at Northwestern University, Evanston, IL, have some good news for teenagers who missed out on learning to play musical instruments as young kids. Even when musical training isn’t started until high school, it produces meaningful changes in how the brain processes sound. And those changes have positive benefits not only for a teen’s musical abilities, but also for skills related to reading and writing.


Singing for the Fences

I’ve sung thousands of songs in my life, mostly in the forgiving company of family and friends. But, until a few years ago, I’d never dreamed that I would have the opportunity to do a solo performance of the Star-Spangled Banner in a major league ballpark.

When I first learned that the Washington Nationals had selected me to sing the national anthem before a home game with the New York Mets on May 24, 2016, I was thrilled. But then another response emerged: yes, that would be called fear. Not only would I be singing before my biggest audience ever, I would be taking on a song that’s extremely challenging for even the most accomplished performer.

The musician in me was particularly concerned about landing the anthem’s tricky high F note on “land of the free” without screeching or going flat. So, I tracked down a voice teacher who gave me a crash course about how to breathe properly, how to project, how to stay on pitch on a high note, and how to hit the national anthem out of the park. She suggested that a good way to train is to sing the entire song with each syllable replaced by “meow.” It sounds ridiculous, but it helped—try it sometime. And then I practiced, practiced, practiced. I think the preparation paid off, but watch the video to decide for yourself!

Three years later, the scientist in me remains fascinated by what goes on in the human brain when we listen to or perform music. The NIH has even partnered with the John F. Kennedy Center for the Performing Arts to launch the Sound Health initiative to explore the role of music in health. A great many questions remain to be answered. For example, what is it that makes us enjoy singers who stay on pitch and cringe when we hear someone go sharp or flat? Why do some intervals sound pleasant and others sound grating? And, to push that line of inquiry even further, why do we tune into the pitch of people’s voices when they are speaking to help figure out if they are happy, sad, angry, and so on?

To understand more about the neuroscience of pitch, a research team, led by Bevil Conway of NIH’s National Eye Institute, used functional MRI imaging to study activity in the region of the brain involved in processing sound (the auditory cortex), both in humans and in our evolutionary relative, the macaque monkey [1]. For purposes of the study, published recently in Nature Neuroscience, pitch was defined as the harmonic sounds that we hear when listening to music.

For humans and macaques, their auditory cortices lit up comparably in response to low- and high-frequency sound. But only humans responded selectively to harmonic tones, while the macaques reacted to toneless, white noise sounds spanning the same frequency range. Based on what they found in both humans and monkeys, the researchers suspect that macaques experience music and other sounds differently than humans. They also go on to suggest that the perception of pitch must have provided some kind of evolutionary advantage for our ancestors, and has therefore apparently shaped the basic organization of the human brain.

But enough about science and back to the ballpark! In front of 33,009 pitch-sensitive Homo sapiens, I managed to sing our national anthem without audible groaning from the crowd. What an honor it was! I pass along this memory to encourage each of you to test your own pitch this Independence Day. Let’s all celebrate the birth of our great nation. Have a happy Fourth!

From Songbird Science to Salsa Dancing

Posted on by

Erich Jarvis spends his days at the Rockefeller University, New York, studying songbirds and searching for clues about the origins of language. But at least two nights a week, you won’t find this highly accomplished neurobiologist mulling over the latest neuroscience results or shooting an email to colleagues about their ongoing efforts to sequence bird genomes. He’ll be in the dance studio, practicing his latest salsa dancing moves.

In fact, before even considering a career as a scientist, Jarvis was a dancer. He danced ballet in grade school, later enrolling in New York’s High School of the Performing Arts as a dance major. Between academic classes, he spent three hours each day practicing ballet at school and, as a teen, another three hours each night practicing solos and pas de deux at the renowned Joffrey Ballet School and, later, the Alvin Ailey American Dance School. Jarvis even received an invitation as a high school senior to audition for the Alvin Ailey American Dance Theater.


How the Brain Regulates Vocal Pitch

Whether it’s hitting a high note, delivering a punch line, or reading a bedtime story, the pitch of our voices is a vital part of human communication. Now, as part of their ongoing quest to produce a dynamic picture of neural function in real time, researchers funded by the NIH’s Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative have identified the part of the brain that controls vocal pitch [1].

This improved understanding of how the human brain regulates the pitch of sounds emanating from the voice box, or larynx, is more than cool neuroscience. It could aid in the development of new, more natural-sounding technologies to assist people who have speech disorders or who’ve had their larynxes removed due to injury or disease.
