I put together this animated sequence of the media from Post-prepared Piano to illustrate the relationships between the spectral analysis, the mapping with nails and twine, and the music from the piece. Thanks to Photosounder developer Michel Rouzic for suggesting that I make a video combining the sound and imagery after seeing the documentation I posted a few days ago.
This is an excerpt from a performance by DKO from the MCAD MFA open studio night on December 7, 2012 as discussed in the post Live Binaural Recording of DKO with Oliver Grudem. 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. The visuals and sound from his walk provided a “score” for us to respond to as we improvised. Oliver was also able to hear our musical reactions to the audiovisual score as he was broadcasting and respond accordingly.
The piece was recorded with my custom built binaural head microphone to capture the sound localization of the performance space. NOTE: It is necessary to wear high quality headphones to experience the binaural effect. The spatial properties of studio monitors are also acceptable but will not produce the same localization of the sound sources. Thanks goes out to Eric Dowell for shooting video of the one hour long performance. I am working on editing a shorter version to briefly summarize the essence of the piece. This 13 minute video is a more in depth snapshot of what the performance entailed.
Recently I have been working on an eight channel, spacialized sound, projection, and dance collaboration. I composed the music entirely using my collection of analog synthesizers. I also designed an octal sound system (eight discrete channels) to spacialize the music and sounds. The performances are Thursday, June 7 at 9pm, Friday, June 8 at 9pm and Saturday, June 9th from 9pm until 6am (yes that is 9 long hours). Checkout In Habit: Living Patterns for the location and other details.
Here’s how I am processing the music for spacialization. The outdoor stage is a raised 18′ x 18′ square that the audience can view from any angle. At each corner I have outward facing wedges to project sound toward the audience. Behind the audience I have inward facing speakers on stands, also at each corner of the venue (a public space under the 3rd bridge in Minneapolis).
Using a Max for Live patch that I developed and another that is part of the M4L toolset I am able to rotate sounds around the system in many ways. This includes clockwise and/or anti-clockwise at variable frequencies around the outer or inner quads or both. I can also pan sound between the inner and outer quads with or without the rotation happening simultaneously. Quick adjustments allow me to create cross pans to for sweeping diagonals and so on. I originally thought I could do this with one of many M4L LFOs, but found out this would be impossible. In a future post I will explain why I had to develop my own patch to do this. For now, please enjoy a sadly two channel rough mix of Kolum, the second in the series of sixteen vignettes, and come to the performance to hear it in all of its spatialized, eight channel glory.
