On tour with Paul Simon in the late 1990s, musician Mark Stewart bought his first didgeridoo, a hollow wind instrument from Australia known for its sonorous quaver. Once home in New York, Stewart was walking in the Garment District when he noticed something. In a dumpster were the cardboard tubes, of all different sizes, used to hold bolts of fabric, echoing the familiar cylindrical shape of his new instrument.
“Every single tube was a column of air waiting to be played,” Stewart recalls. As he tells it, he clambered inside at once and began to assemble and play these tubes in an impromptu performance. He began to see the world as raw material, even its most quotidian shapes containing a wealth of sonic possibility. Everything, it appeared, was a potential didgeridoo.
Stewart — a world-class multi-instrumentalist, singer, composer and instrument designer — embarked with MIT’s Glass Lab upon a new challenge: creating an assortment of original instruments entirely out of glass. With Glass Lab Director Peter Houk, Stewart led yearlong workshop to explore new sounds through the design of glass instruments — with an emphasis on the new and bizarre.
The partnership was a natural one. The Glass Lab is a place where “everything is worth exploring just because it’s an idea,” says Glass Lab instructor Martin Demaine, the Angelika and Barton Weller Artist-in-Residence in the Department of Electrical Engineering and Computer Science. Built in the late 1960s as part of the Department of Materials Science and Engineering, the Glass Lab offers students the opportunity to observe first-hand the material principles learned in the classroom. The lab’s enormously popular non-credit workshops demonstrate that artistic production and academic study can be overlapping courses of exploration.
In this same spirit of playful inquiry, Stewart approaches the work of instrument building. Most of what he knows about the physics of sound making was learned through trial and error. Making sounds, he believes, is instinctual and needs no formal training. “The word ‘musician’ is too often used to discourage people from participating in their birthright as sound-makers,” Stewart says.
Like a tinker, he often carries with him a seemingly bottomless bag filled with his creations. On his first exploratory visit to the Glass Lab, Stewart rolled out a motley bunch of homemade instruments crafted from PVC pipes, bouncy balls and coat hangers. Everyone in the studio froze as a swell of new sounds emerged. With these appealing yet oddball instruments, Stewart hopes to incite untamed sound making through the power of sheer, unexpected sensorial delight.
In Stewart’s philosophy, each instrument holds a kind of cosmic purpose, possessing an intrinsic sonic quality that is theirs alone and our role as sound makers to bring forward. He speaks of sounds in evolutionary terms — as if they were living organisms, each with its own essential function fitting perfectly into the larger aural ecology. Some sounds, such as those of the versatile and ubiquitous piano, have found currency in their integration into bands and orchestras — which amount to the star makers of the sound world. Other sounds are unrealized or have wound up neglected in strange historical cul-de-sacs, doomed to near extinction. These are the sounds — the atypical, original, and unheard of — that interest Stewart the most.
At MIT, Stewart enjoyed collaborating with kindred spirits. Of the first meeting with Houk and others at the Glass Lab, he recalls, “There was this feeling, ‘Why don’t we just build everything?’ I felt light-headed with possibilities.” Stewart had never worked with glass before, and was anxious to discover what new kinds of instruments the material might yield. The Glass Band made their debut at the Center for Art, Science & Technology’s five-hour Marathon concert, a performance traversing the spectrum of contemporary musical practice.
