Musical Synthesis and Sonic Environments

Architectural Drawing of the SRT from Tonkin Liu

I am quite honored to have an article about my recent work published by the American Composers Forum (ACF). The article was written by ACF member Timothy Hansen and is available here. The focus of the piece is on my duets with the Singing Ringing Tree. From the article:

On a bare hill overlooking the village of Burnley in Lancashire, England, stands the Singing Ringing Tree, an array of galvanized steel pipes stacked in a swirled sculpture to resemble a stylized broad-boughed tree. Standing alone on this otherwise empty hill it is visually striking enough, but it’s when the wind picks up that the Singing Ringing Tree’s true purpose is revealed. A haunting chorus of hollow, almost ghostly tones fills the air, making the open sky seem wider than before, stretching from horizon to horizon over a broad, clear landscape: the Tree and its disembodied chorus starkly underlines that, here, you are alone.

This concept of an artificial “sonic environment” was arguably born through the work of John Cage, perhaps the first and fiercest proponent of listening to one’s surroundings as music. His infamous 4’33” kick-started a whole branch of composition where “non-musical” environmental sounds become an integral part of the piece.

British born John Keston is one of Cage’s modern-day disciples. Cage had already been a longtime influence on Keston when he commenced his masters program at Minneapolis College of Art and Design, but while at MCAD, Keston began to move beyond simply listening to his environments as sources of music and started considering them as collaborative partners. Armed with a synthesizer, he began to create a series of sonic environment duets.

“I started these duets close to home in Northeast Minneapolis,” explains Keston. “My neighborhood is crisscrossed with railways, rail bridges, and rail yards. I found that I could coax music from everyday ambience by emphasizing rhythms and textures with a portable synthesizer.” Once he had exhausted the possibilities of his local neighborhood he began to search for, as he describes it, “more exotic locations.” This was how, in 2014, with the help of a grant from the Jerome Fund for New Music, Keston found himself seated at the foot of the Singing Ringing Tree, ready to create a series of new duets with his strange, lonely collaborator.

“I did not compose any music ahead of time,” says Keston. “I knew that I needed to experience the Singing Ringing Tree in the flesh to legitimately collaborate with it. The music from the Tree can change dramatically by the minute. On one of the five days I was there it was mute when I arrived. A few hours later it began to sing quietly as the wind picked up. My approach was to let myself react to what it did from one moment to the next. There was no way to direct my collaborator. This was liberating because I could only accept, appreciate, and respond to its performances.”

Keston’s sonic environment duets are especially unique to his practice due to a lifelong fascination with synthesizers. “When I was ten my Dad brought home two records by Isao Tomita: Firebird and Pictures at an Exhibition,” Keston recalls. “I was immediately fascinated by the sounds on the recordings. The album cover of Pictures at an Exhibition showed the room sized Moog modular synthesizer that Tomita was using. The images of the mysterious technology and the fantastic sounds spurred my curiosity. Later as a teenager living in the States I managed to buy my first synth; a Moog Rogue with a broken key.”

Today, synthesizers are an integral part of Keston’s practice, which draws from the gamut of music technology and new media. Keston also has a background in software development, enabling him to build software and hardware from scratch to serve his artistic goals. But his motivation for creating such work goes beyond artistic impulse: Keston believes his work serves to humanize music technology. Keston explains:

“If we are going to use technology to create art then I feel it is necessary to inject the human engagement of technology transparently into the work in order for it to reflect the contemporary human condition. If not, then the art might be mistaken for art created by machines rather than art created by humans with the aid of machines. Don’t get me wrong. I am fascinated by algorithmic music, and the idea of art created by artificial intelligence. I look forward to experiencing art that is fashioned entirely by AI. Duets with the mechanical environments we live in using electronic devices to mimic or contrast the sonic landscape reflect the ongoing amalgamation of people with technology.”

Debut Album from DKO Absinthe Referent

DKO Absinthe Referent

On Tuesday, May 19 DKO is releasing Absinthe Referent, available on cassette (limited edition of 100) and digital download. Although Jon Davis, Graham O’Brien, and I have been performing as DKO since 2011 this is our debut album. We recorded it at Bellows Studio during a live, in-studio concert with an intimate audience of friends and family members.

Graham and I edited the album down to six tracks that we handed off to Adam Krinsky for mixing. Finally we had it mastered by Huntley Miller. Please listen to a preview track from the album titled S33LUgRUN. We will be performing to celebrate the release on May 20 at the Turf Club in St. Paul, Minnesota with Dosh and A Love Electric.

New Spectral Tablature Collaborations Exhibited in Tokyo

I am pleased to be participating in an exhibition of work by Jasio Stefanski at Print Gallery in Tokyo, Japan. Jasio is showing a variety of his work including two pieces that we collaborated on together fron the series Spectral Tablature. The first piece is Synthetic Skyline previously exhibited for the Audible Edge sound art exhibition at the Katherine Nash Gallery in Minneapolis. The second piece is a new work in the series titled Synthetic Transitions.

Synthetic Transitions



To create the work I started by composing a simple sequence of notes that speed up and then slow down. Jasio requested that we included diagonal lines in the piece so I used linear portamento on the Moog Sub 37 to create the “transitions” he was interested in seeing. The video shows the plotter rendering Jasio’s Reprise of the work shown/heard in the image/audio below.

Synthetic Transitions Reprise



Jasio’s Reprise is based on form and color values as opposed to acoustic accuracy. The visuals were composed to place emphasis on the “transitions” or portamento. The output visually reinterprets the angles informed by the gliding notes without connecting them in the composition. When sonified the plotted design singles out the portamento, isolating it from the context of the sustained frequencies.

Video: Are You Hiding by Camp Dark

A couple of months ago I spent about 18 hours over two days recording synthesizers for the upcoming Camp Dark album Nightmare in a Day. It was a blast and the music is gorgeous. I wrote in more detail about the project here. The latest video, edited by Adam Svec, is for the song Are You Hiding. This one ends with a long passage of Moog Sub 37 running through the Minifooger Delay as I twisted the Time and Feedback knobs.

Are You Hiding” is the second video in a series to promote the release of Camp Dark’s new album, Nightmare In A Day (Icehouse MPLS on Friday 5/15). The story was inspired by holiday trips back to South Dakota. The song navigates the trajectory of playing roles of earlier versions of you. This veneer eventually falls apart when the years become visible. A person can only hide in plain sight for so long before they are spotted. It’s an anthem of empathy for those who experience this distance between former and current selves. “Are You Hiding” features performances by Graham O’Brien, Adam Svec, Dan Choma, Matt Leavitt, Matt Friesen, and John Keston.

Erik Thompson included the video in his “Top 10 Must-See Minnesota Music Videos This Week” series at the City Pages. Oh yeah, and we’ll be performing at the Icehouse in Minneapolis on May 15, 2015 to celebrate the release.

New Spectral Tablature Collaboration

Spectral Tablature 2015

Part music, part visual art, and part sound design, the collaborative series Spectral Tablature is something I’ve been doing in various forms since 2013. Recently I have been working on a new piece in collaboration with Jasio Stefanski for an upcoming exhibition of his work. I’ll share more information about the exhibit in a future post. For now I’d like to present some of the content that I generated in the process of working on the project.

The image above is spectral analysis of a piece of music that I composed deliberately to produce interesting sonic and visual forms. The piece includes three layers of sequences that slowly speed up and vary in pitch and then slow down again. The speed of the sequence was based on an LFO with a variable rate rather than BPM. This process, along with other techniques, resulted in a form that starts simple, approaches entropy, and then returns to its original simplicity.

Example with Portamento

The final piece will be reprocessed visually through a set of design criteria determined by Jasio. Once the new design has been printed I will digitize the image and reprocess it as sound. The new audio will retain the original frequencies and temporal information but the textural and timbral qualities will be completely transformed.
