“Timebral Artifacts” Soundscape for Busker’s Day

Studying the effects of waveforms in a sonic environment and transmitting those waveforms to audio cortices is a mission of iBoD. To that end, we have partnered with three synthesizers to explore the ways of waveforms. First came the Behringer Nuetron, which is a puzzle and a playful soundshaper. My first challenge was (and continues to be) getting sound out of it (VCA Bias and Overdrive Level knobs need to be wide open.) Nuet has lots of internal routings and moveable parameters including blending between oscillator waveform shapes, and multiple LFOs and VCFs. Next came the Moog SubHarmonicon, which is extremely fun and responsive and more intuitive. These two are “tied” together by the Make Noise O-Control, which serves as a sequencer for Nuet, and receives clock from Moogie. So that is my crew for this event: Nuet, Moogie, OC and me.

Using internal and external routings, iBoD explores the shifts in timbre and rhythm presented by the synthesizers. These instruments make sound from oscillating frequencies shaped by waveforms and envelopes, which are the basic building blocks for timbre (and EVERYTHING, but THAT is another story, which can be read in the links below). All of the action is triggered, directed, and massaged by control voltages. Sparks of electricity drive the whole show, which makes for alot of unpredictability and maleability.

A friend asked me “What is timbre?” Yes, we are all familiar with rhythm and melody, but timbre is a kind of behind the scenes aspect of musical sound which isn’t as easily apprehended because it is so essential. Timbre is the “dna” of sound presented in harmonic code. Our brains decipher these codes so we can discern a foghorn from a racing engine from a baby crying. Please read these previous posts where I offer my understanding of timbre:

The Law of the Octave

Nature’s Chord

So that is what I will be playing with on Saturday. Since my favorite part of symphony concerts is the settling in and tuning that the orchestra does before they start the program, Timebral Artifacts will begin with some tuning and retuning of parts, followed by propagation and meanderings until an undercurrent of structure appears. When this happens, I will play Native American flute in call and response play with the synths.

iBoD will play from 2-2:45 pm. See map of Sculpture Garden for exact location (2a)

I hope you will come and listen!
