Sounds Like Art

Alex Braidwood captures the audio wonder of life.

When Alex Braidwood trains his Iowa State University students to listen better, sometimes he’ll ask them to plop down somewhere on campus, pull out a notebook and draw a map of every single sound they hear—near, far, quiet or loud. But instead of telling them to draw a bus, for example, he asks them to sketch a visual image of the sound itself, “the WHOOZH-WHOOZH-WHOOZH and then the eeeeeee of the brakes.”

To do that, he says, students have to consider the specific qualities of each sound—its timbre, its color, the way it starts and fades away. Is it biophonic, like birdsong? Or geophonic, like rain? Or maybe it’s anthrophonic, human-made, like that big old bus.

“We spend so much time trying to block things out with headphones or when we hop in the car,” he says. “It’s rare to spend time really listening to the places where we are.”

But Braidwood’s own ears get lots of practice. The multimedia artist teaches in several programs at Iowa State—graphic design, sustainable design, human-computer interaction—and he studies soundscapes, which comprise all the sonic details that make one place sound different from another. He can talk about sound the way a painter talks about light or a sommelier talks about terroir.

When I met him this summer at his house, in the woods northwest of Ames, he led me out to the back deck. Hidden birds chattered in the trees. Cicadas buzzed to beat the band.

Braidwood’s ears have heard things all over the world, from a Chinese train station to an Indian tomb to an Australian national park, but one of his favorite soundscapes is in his own backyard. He loves the dawn chorus, right before and after sunrise, when all the critters are especially lively.

He moved here last year from downtown Des Moines, where his ears perked up for different reasons.

“You hear this massive roar and rumble” when trains pass over the bridge on the Des Moines Riverwalk, he says. Farther south, along Martin Luther King Jr. Parkway, the trains bounce noise off the canyon of brick warehouses, especially in the winter, when snow muffles everything else.

‘Listen Right Here’
Last year he installed solar-powered recording devices at five locations in Des Moines: an alley behind Kitchen Collage, the Des Moines Social Club courtyard, the DART bus station, Crane Artist Lofts and a house near Keosauqua Way. After a few weeks, he dropped the recordings into a computer program that randomly twisted the audio strands into music he then pumped from a ring of speakers at the Des Moines Art Center. The mashup of cars, sirens, jets, helicopters, skateboards and heavy construction machinery was surprisingly soothing.

“There was something very calming about it,” Art Center curator Laura Burkhalter says. “The staff said we should put beanbags in the gallery because people wanted to sit down. It had an almost physical effect on them.”

The project, called “Listen Right Here: DSM,” required Burkhalter to “find a new language to talk about the artwork,” she says. “Art is about perception, but we fall back on the visual so often. [Braidwood’s] work captures a part of life that we often take for granted.”

People don’t always expect art and science to overlap, but really, they’re just different ways to figure out the world. Braidwood dabbled in both as a kid in northern Michigan, and he was always fascinated with recording gadgets and computers. As a high school sophomore, he “slid in” to an art class at the local community college—his teacher mistook him for a senior—which inspired him to study graphic and interactive design at an art school in Detroit.

“By that point, I was completely sucked in,” he says. He enjoyed the challenge of combining his skills as an artist, musician, photographer, videographer and computer programmer. He and his classmates learned about a new-fangled wireless technology called Bluetooth, back in 2001, and tinkered with other marvels of the new millennium.

“We were going to Best Buy to play with PalmPilots to see what they were all about,” he says.

That curiosity still drives him now, at 38, when a grayish beard that could hide all sorts of microphones hangs halfway down his chest.

“He takes these difficult techy things and brings a real childhood joy to them,” Burkhalter says. “It seems almost like magic.”

Acoustic Ecology
For the past few summers, Braidwood has directed an artist-in-residence program at Iowa Lakeside Laboratory, which the three state universities operate in Okoboji. He teaches acoustic ecology there and keeps an eye on a tricked-out buoy he dropped two years ago into West Okoboji Lake. Its sensors record various data about the water—temperature, oxygen levels, pH balance—which Braidwood translates into fluctuating layers of music, similar to his project in Des Moines. If the water’s surface temperature is 68 degrees, for example, his computer program might start at the 68th key on a piano and then move up or down the scale as the water warms or cools.

“If you think about water quality, especially in the lake, there are these cycles,” lab director Mary Skopec says. “There are a series of highs and lows throughout the week. There’s a pattern that he uses in the music.”

She recalled one scientist who listened to the music and heard a slight variation—a wrinkle in the pattern—that signaled a change the researchers might not have noticed by studying the charts. As it turned out, one of the sensors had malfunctioned.

The music “helps us understand the lake in a way we might not be able to otherwise,” Skopec says. “It can show us something we’re missing.”

In 2016, Braidwood installed a solar-powered recording device at the DART bus station
and a handful of other downtown sites. He wove the clips into a sonic tapestry for a project called “Listen Right Here: DSM” at the Des Moines Art Center.
Like a photographer who still uses film, Braidwood often records his work on cassette tapes rather than digital files because he likes the notion of sound as a tangible artifact or piece of art.

Intentional Listening
But we’re missing more than whatever lurks underwater. Braidwood’s mission is to get people to pay attention to the sounds in their everyday lives. He launched an initiative called Listening Instruments ( that includes an array of workshops and projects to encourage people to use their ears more intentionally.

“Listening to the surrounding soundscape, wherever you are, is an experience I hope more people will embrace,” he said in an Art Center handout. “It provides so much information about place and community, about priorities and opportunities.”

Whenever Braidwood leads listening tours around town, he asks the groups to be quiet and listen for 30 uninterrupted seconds. That isn’t a long time, but it feels like an eternity if you usually rush from one thing to the next.

I tried it in Braidwood’s driveway in Ames, on my way back to the car. A twig snapped. A breeze rustled the trees. Cars whistled by on the county-line road. My pen whispered across the lines of my notebook.

It occurred to me that if the local food movement ever fizzles out, maybe we should try local sound. There’s a lot to take in.
