The Sourdough Project

A major soundscape creation for 2019 is to sonify data for the Sourdough Project. The Rob Dunn Lab at NCSU, the Ben Wolfe Lab at Tufts, and the Noah Fierer Lab at the University of Colorado are collaborating to further the study of microbiomes in sourdough starters. The Sourdough Project has gathered starters from many parts of the world in order to study the bacteria and yeast interactions that create the fermenting acids and leavening gases necessary for the creation of sourdough bread.

In October 2018, the Sourdough Project Team and two artists met at the As If Center in Bakersville NC. The As If Center (Art and science In the field) is the burgeoning vision of Nancy Lowe, who is keenly interested in exploring this fertile collaborative area.The other artist was Ferne Johannssen, freshly graduated from college, and off to see what life outside of Vermont has to offer. Ferne is a visual artist/printmaker. [Interestingly, Ferne made a print on a scoby (symbiotic colony of bacteria and yeast) which grows and ferments in kombucha tea.] The purpose of our meeting was to seed an artistic and scientific direction for sharing the data from the Sourdough Project. All three labs were represented and we spent most of our time sharing information and structuring the research paper that will come from this study. Here is a description of the study from the Rob Dunn Lab website:

There are millions of kinds of bacteria and fungi on Earth. We have found several thousand species in human belly buttons alone. Yet if you mix flour and water, the community of organisms that colonize the resulting concoction is almost always composed of a small handful of organisms that are able to leaven bread, yielding a sourdough starter. How this happens is one of civilizations great mysteries, a mystery at the heart of the bread making (and, for that matter, traditional beer brewing). Yet, while bakers understand how to make starters, the underlying biology of the species in these starters remains mysterious. Starters can produce similar effects on bread (and similar flavors), despite being composed of different species, a key different ingredient. Conversely, starters composed of the same species sometimes yield different flavors. Then there is the issue of what happens to starters over time. The organisms in starters are hypothesized, by some, to stay the same over time—an old growth forest of miniatures—even if their living conditions change. Few ecosystems are so (apparently) stable. Then again, starters can change through time, sometimes suddenly. Starters are, if anything, predictably mysterious. But not for long. We aim to understand the biology underlying the differences among starters and the changes (or lack of change) in starters through time.

The last sentence of this description is what I honed in on. My current sense of how to render data as sound is that it would be most effective with data changes (or lack of) across a timeline. The other word that caught my eye is biology. What is biology? The science of living matter in all forms and phenomena, with special reference to origins, growth, structure, behavior and reproduction. The bases of biology are macromolecules (proteins, lipids, nucleic acids and carbohydrates), cells, and evolutionary changes creating phylogenic families across species. With sourdough starters, we are at the microbial layer of life. On the microbial level, diversity rules and it may have something to teach us. That is what I hope!

The Sourdough Project team had a conference call a few weeks ago, where we saw some of the data analysis of the samples, and received updates from each of the labs. Patterns are starting to emerge as the data is narrowed and focused into categorical relationships. This is the crossroads where it all comes together in the question: What do I want from this data? This most interesting question was posed our first night at As If Center, as we sat around an outdoor fire: what is your currency? what do you want from this project? I can’t remember ever having been asked that before.

The bakers who sent in samples want to know the microbiotic fingerprint of their particular starter. The scientists want to discover some new information about the ecologies of sourdough starters in general. The artists are interested in translation, transposition, representation of the discoveries found in the fingerprints. For myself, I am looking to identify a timeline and voice the bacteria-yeast exchange that is fermentation and leavening. Here is a diagram of a potential time frame:

Water + flour =

aab(acetic acid bacteria) ~ LAB (Lactic Acid Bacteria) ~ Yeasts

which give rise (the timeline but also a phase within the process)

to VOCs (Volatile Organic Compounds) aroma

To my ear this begins with the very lively interaction of the organisms that changes over time into a lighter, gaseous state. There is an alchemy that takes place and we are trying to hear and understand that.

Still looking at TRIC (Terry Riley’s In C) as a template for orchestrating interesting timbral relationships in this context. Pattern 35 is a possible frame for rise which seems to be the name of this piece. Pattern 35 jumps to a start with an eighth note run. This is the organism interaction phase. Then the mid section is where the rise happens with more space and elevation in tone. Then the aromatic texture is very open and light and unfinished.

What other sound elements might lend to this soundscape? There are likely real live sound samples to be had from this process. Another thought is what if each starter could have its own microbiome sounded out? To do this, I need to see more deeply into the data then I have to this date.

More to come…

Modular synthesizing in Ableton Live

Even though I have worked intimately with Ableton Live DAW (Digital Audio Workstation) for over eight years, I KNOW I have only scratched the surface of its capabilities. In the last few years, I have come to think of Ableton Live as my “instrument”, my medium, what I create with. What an incredibly rich and mysterious instrument it is! Now I am enamored of modular synthesis, striving to be come engaged with modular synthesis, particularly Eurorack modules. I love the knobs and sliders, and the patch cables just put me over the top. Modular synthesis is like sonic legos, a form of prayer, and a particular patterning of vibrations that matter. I want to plaaayyyy!!

This is the 2019 plan: spend time researching, listening to and playing modular units. I am learning about how modulars work by playing with the Ripplemaker ios app on iPad. Ripplemaker is a semi modular synthesizer which means that some of the signal routing is already patched together. Ripplemaker contains five modules, an LFO and amplifier/mixer, so it is a good basic learning tool. In addition I am studying the book Patch and Tweak which just came out a few months ago. It is a comprehensive survey of modular synthesis from the basics, to the gear, to the practitioners. I bought the book because it contains an interview with a performer whose work I admire tremendously, Caterina Barbieri. The book is a treasure trove of information that I am studying every day. The write ups about all the major brands and models of Eurorack synth modules is amazing. While Patch and Tweak could pass as a coffee table book, it is a bible to me. While doing all of this, I will save the money to buy my first modular synth unit. This could happen at Moogfest, or sooner depending on the progress of research and saving.

As for now, I have invested alot of time and money in Ableton Live and my computer set up, which is essentially a soft synth – I just need to configure it as such. Up to this point, I have treated Ableton as a composition tool/recording studio for the most part. I have been performing with Ableton and learning how to use the control surfaces (Novation LaumchPro and AKAI Key 25) to create soundscapes in real time. Now I want to configure and play Ableton more like a synth. This new approach will mean I have to deeply learn all the audio effects in Ableton, and other external plugins. I can configure the control surfaces to function as synth controls by mapping the parameters I want to sculpt with to the knobs and sliders of the control surfaces. The rest is signal routing.

Ableton Live is so robust and complex that the signal routing possibilities are numerous. Audio effects can be placed on tracks, within tracks routed together through a group submix, within a clip, within send/return tracks, on the Master track. Then within the larger set, tracks can be routed to and through each other using the in/out sub menu embedded in each track. So, with this in mind, how can I create control voltages, oscillators, slopes, envelopes, LFOs, Noise, and other modulators and configure them and play with them within Abelton Live?

The journey begins…

Minding the Oscillations

Reading deeply into sound, physics, chemistry, and nuerobiology, it becomes clear that lived experience is comprised of waveforms modulating each other. These waveforms weave around and through us. The waves are different frequencies and different amplitudes, they have different shapes and resonances AND they interact with each other, all of which creates various densities of matter. As extreme examples, there is a diamond and a thought. These extremes define the boundaries of material experience – the hatd shell of the matrix we exist within. There is more beyond these boundaries, and the more seems to be the field of conciousness.*

With this as a basic understanding, it is my intention to mind the oscillations, particularly those that eminate from my human being/my earth suit/the event horizon of my world. The waveforms I conjur come into phase relationships with themselves and with the waveforms of other human beings as we event our common reality/the hard-shell matrix. This is an amazing realization! This realization sheds light on a major question I have danced with in my life:

How can I be more loving? So much of my living is spent seeking love from “the world”. That was my quest for the first half of my living experience. While it does hurt so good, I finally realized the question is framed in an unhelpful way. So I am moving from how can I get more love, to how can I be more loving?

My most important practice for exploring this question is awareness and presence in the moment. We have been listening to Eckhart Tolle go on and on about this. He works very hard to articulate awareness/presence in all the ways that might possibly bounce around (or cut through) the mind. Listening to ET, I am aware of the trinity of self, egoic mind and conciousness all walking into a bar. (It is a good practice for them to stick together, although the bar was probably egoic mind’s idea.) These three are waveforms of their own, and their interactions eminate into manifest world! These two thought-fields (waveforms of matter and awareness through being) intersect at my heart.

One definition of oscillation (from physics) is

regular variation in magnitude or position around a central point

This aptly describes the interplay of these two planes intersecting through me at heart center. I feel this most intensely when I am sounding harmonics through a space. Especially using modular synthesis – with all the operators, envelopes, slopes, attenuations, triggers, gates and frequencies- to create actual sonic forms in space. At present I play with Ripplemaker ios app from Bram Bos. It is great to learn on. Ableton can function as a synthesizer. This is my focus at present- to configure Ableton into a synthesizer. (I am deeply desiring a modular system, but must go slowly due to funds. So work with what you have!)

This first week of 2019 – a new year (marking earth’s intersecting oscillations with the sun, moon and stars) brings some interesting mantras –

Listen more deeply, mind the oscillations, propagate harmonic vibrations, learn to play with forms, depersonalize the whole thing! The WoW

Alrighty then!!…on with the emanations!

Human Origami Soundscape Dec 7 2018

Today at 3 pm, Glenna Batson will lead an exploration of folds and resistances. In her words:

What happens when awareness meets a curved line, a folding surface, a deepening crevice within the body’s interior and the surround? Is the quality of this first contact fixed or free? Is the conversation open or resistant? Is there a clear beginning and ending? It’s at this junction between folding and unfolding where new possibilities for negotiation arise – where a boundary can become more porous and transparent. In this session, movers will uncover the rub of resistance within themselves and open the conversation to new movement possibilities.

The soundscape for today’s playshop will be a piece from Audiorigami (Meditations on the Fold) interspersed with modular synthesis play in formless to form and back again. The Audiorigami track is called 11th Harmonic and consists of overlapping 11th harmonic intervals. This harmonic at extremely high frequencies has been shown to break up tumor cells! The Law of Octave allows us to bring the high frequency into the audible range, and benefit from the entangled resonance with the higher frequencies.

11th Harmonic is a kind of smudge soundscape. It has the capacity to clear stuck energy in a space, in a body, so is perfect for the suggested intentions Glenna has put forth. This piece has five or six movements, and the parts are layered in and shimmered over each other. This is an example of how I have created audiorigami to this point. Now there is new direction in the form of Ripplemaker – even the name suggests the Fold!

Ripplemaker is an iOs semi-modular synthesizer. Synthesizers play electrical signals or control voltages. These voltage-based signals are shaped by waveforms, oscillators, envelopes, filters and effects into sound sculptures. Modular synthesizers can illustrate the journey from the formless into form in amazingly beautiful ways! And the journey is accomplished through folds. The basic structure of this sound material is the waveform, and each waveform highlights the harmonic overtones in different ways. The waveshape is then propogated, expanded, attenuated, filtered, timbrally-morphed through oscillators, envelopes and filters. The journey is amazing and intense, so each mod synth excursion will be followed by a bit of room resonance and breath. Then 11th Harmonic will return.

Very excited to give this voice today at 3pm at ADF Studios. Please come and play with us!

Voices from Eris – Various Artists

Voices from Eris is a compilation of women electronic artists from around the world. The brainchild of Margaret Harmer of Shifting Waves Studio in Geneva, Switzerland, the album is a cauldron of sound shapes that interweave and connect far beyond the individual voices of each woman. You will hear the song of rocks, sirens, the trapped and the free. You will hear the sound of the deconstruction of patriarchal structures, and the spinning of new and dynamic sonic forms that are flexible and expansive.

Here is a link to the crowdfunding site for the album, where Margaret illuminates the inspirations behind the album title, the larger signifigances of “Eris”, and why we feel compelled to express ourselves at this moment in time.

https://wemakeit.com/projects/voices-from-eris

This is not your typical music album, so I feel the need to help you hear exactly what it is we are doing. Unfortunately, many people bring their “music” ears to these pieces, with all the evaluative frames entailed in “listening to music.” These frames interfer with the listener’s ability to access sound paintings. If you have ever experienced Magic Eye paintings, then you know that looking at them with “what is this a picture of?” eyes makes the form of the picture completely inaccessible. In order to see deeply into a Magic Eye painting, one has to relax the gaze, soften the eyes, and surrender mind/awareness, only then will the form in the painting emerge. When this same kind of deep gaze can be translated to a deep listening – the soundscapes become mesmerizing and create new worlds in the brain ear.

On behalf of all of the artists on the album, I appreciate your love, respect and support for this project! Help us make it happen!!

Bandcamp CD Release: Audiorigami (Meditations on the Fold)

Human Origami is an ongoing movement/sound project to which I contribute along with Glenna Batson and Susan Sentler. On our website, http://humanorigami.com, you can explore who we are and all the ways we are playing with folds. This project was inspired by a seed idea from 20th Century French philosopher Gilles Delueze’ The Fold. In this treatise on the Baroque period, Delueze asserts that the smallest unit of matter is not the point, but the fold. He describes the fold as a unit of oscillation, along with the point and the wave. My interest is the intersection between sound and movement within and throughout the fold.

For the past several years, Glenna and I have offered a series of workshops where folds were investigated in depth and breadth. I have written about these experiments in three blog posts linked here: (https://wp.me/p5yJTY-c9) (https://wp.me/p5yJTY-cy) (https://wp.me/p5yJTY-gi) Now it is time to manifest what I have learned.

After much experimentation and reflection, a number of ways to find and create folds in sound became apparent. After all, sound is oscillating air, so the very form of sound involves folds. From there:

Rising and falling, overlapping, and reaching back (all actions associated with folds) can be orchestrated musically. One technique used to create “reaching back” is to feature overtone harmonics. By this I mean, playing the interval notes to a fundamental tone in the octave in which they naturally occur in the harmonic overtone series. For example, the first harmonic in a series is the octave above the fundamental. In the second octave above the fundamental, we hear a fifth then the next octave tone. In the third octave we hear the third, fifth and flatted seventh. The fourth octave layers in the second and the raised fourth and the sixth. Normally when these intervals are played over one or two octaves they are heard as scales and chords. Articulating them in their natural harmonic series “home” octave creates a harmonic reach over multiple octaves, and a fold back in reference to the fundamental tone.

Other techniques for more concrete renderings of folds are melodic lines that reach out from and come back to a fundamental tone. On the page, one can see how the melodies move up and down notationally. Percussive sounds are used to define the edges of a fold. A formal quality of folds is repetition. For example, two types of audio folds are 1. an echo, where the sound comes back on itself like two halves of a folded sheet, and 2. a spiral, where the feeling of the sonic movement is a perpetual reaching towards the fold, but never completing it.  Folds require a doubling back that is repetitive and ever shifting.

With these gestures in mind, here are the track notes for Audiorigami (Meditations on the Fold):

First Folds is in two parts and accompanies Glenna’s meditations on the primal unfolding of body from spine in utero. It begins with the sound of heartbeat and rushing blood. Then waves of lovely tones intermingle, slightly muted, rising up and down in a short, repetitive theme that will return in later sections. The piece begins in a still, enfolded place and moves out into form.(12:53)

First Folds Part Two begins with the percussive edges of folds then leads into an emphasis on harmonics -melodic and dissonant. The earlier theme returns to intermingle with alternative themes, all weaving into the fabric of sound as we expand out into extremeties and beyond into ethereal fields. The fold, as articulated oscillation, travels far beyond our corporeal realms. (10:03)

11th Harmonic stretches over four octaves of harmonic overtones. This piece was based on some experiments that demonstrated a particular harmonic interval that could break up stuck cells (i.e. tumors). And while the interval used in the experiments is out of the audible range, the Law of Octave allows the interval to be reduced into the range of human hearing. The primary tonal relationship is rendered as a fundamental frequency and its fifth in the fourth octave above the fundamental. My experience is that this piece is capable of stirring things up on multiple levels. It uses the fundamental to 11th harmonic interval as its basic fold, then builds from there. I played with propagation dynamics in the final mix as a way to move the soundscape closer in and further from the listener. (11:00) An 11/11 wink- I did not plan 11 minutes. I noticed it after the fact.

Folding the Edges (5:15) and Accordion Breathing (6:13) were prompted by Glenna’s idea for a “squeeze box/accordion folds event.” From this I began exploring what makes an accordion fold? This type of fold follows geometric lines, has more symmetry and presents repetitively. Accordion folds have edges – in order to BE an accordion fold there must be two edges that fold away from each other. They hold their shape as they move. The smallest unit of an accordion fold is, interestingly, a tryptych. In these two pieces, there is a strong sense of expanding and contracting, of opening and closing, of breathing with accordion folds. Both soundscapes have edges, repetitive patterns, triad/triplet relationships and breathing space.

Floating Enfolded (10:18) and Floating Downstream (7:02) did not evolve from Human Origami workshops, but were added as part of an online class in Human Origami to be offered in March 2019.
