Spectral Tablature is a series of collaborative installations that explore sound generated through visual processes. Sound is recorded or synthesized using common techniques then converted into images called spectral analysis. These forms are re-interpreted as a visual artifact then converted back into sound. For each pair, or “duet,” the similarities and differences in tone and texture can be heard as well as seen in the work. This series, along with two more of my installations, is currently on display for my thesis exhibition at the Northrup King Building in Minneapolis. Please read on for images and descriptions of each pair of prints along with the audio.

Visual Storage: MFA 2013 Thesis Exhibition

This Friday, May 17 from 6 to 9:30pm (during the opening night of Art-a-Whirl) is the opening reception for the Master of Fine Arts 2013 Thesis Exhibition at the Northrup King Building, Gallery 254, 1500 Jackson Street NE, Minneapolis, MN 55413. I will be showing a series of prints titled Spectral Tablature with an iPad application to “listen” to the prints (more on that later), a 32″ interactive touchscreen installation titled, Machine Machine, and a kiosk with a series of filmed performances. I will also be debuting a performance piece titled, Instant Cinema, featuring DKO (music), David T. Steinman (mobile operator), and Jon Steinhorst (art direction). The performance begins at 9:00pm. Admission is free and open to the public. Two years of hard work has led up to this single night. If you have any interest in art, sound, music, or performance please consider attending. Thank you!
DKO at FRANK Part 3: Everyday Music
This is another excerpt from a performance by DKO from the MCAD MFA open studio night on December 7, 2012. The document features Oliver Grudem (not shown) who produced the audiovisual score in real-time. The video and sound coming from the LED display and loud speaker below it was broadcast into the performance space as Oliver walked around the Minneapolis Uptown area during a snow storm. Listen for traffic, footsteps, car horns, and the occasional blurt of humans speech. The visuals and sound from his walk provided a “score” for the ensemble to respond to as we improvised. Oliver was also able to hear the musical reactions to the audiovisual score as he was broadcasting and respond accordingly.
The piece was recorded with my custom built binaural head microphone (Vincent) to capture the sound localization of the performance space. Remember that it is necessary to wear high quality, circumaural headphones to experience the binaural effect. While watching, imagine you are in the same position as Vincent. You should hear the bass clarinet in your left ear, the Rhodes and synthesizers to the right and the drums and video sound in front. The relative height of the sound should also be noticeable.
Post-prepared Piano by John Keston and Piotr Szyhalski
Piotr Szyhalski and I have just finished installing a piece titled, Post-prepared Piano, in the Burnet Gallery at Le Méridien Chambers, Minneapolis. Our installation is part of a show called Interactions and features the work of select MCAD MFA students in collaboration with their mentors. Our piece consists of several components. The first part is a 14′ wide and 17″ tall inkjet print of spectral analysis from a short piano composition that I performed and recorded using my custom built, binaural head microphone (otherwise known as Vincent).
Below the print is an installation that Szyhalski constructed from tarpaper, nails, and one continuous piece of twine. This handmade mapping of the spectral analysis was then photographed and converted back into sound using Michel Rouzic’s excellent application, Photosounder. Thirdly, we installed an iPad with headphones that allows the visitors to hear the original recording, the nails and string version, and a combination of the two layered on top of one another (visit the tablet optimized webapp). The show opens today and runs through February 24, 2013 with an artist’s reception on January 31 from 6pm to 9pm. Read on for more details, photos and sounds. Continue reading
