String of Yeasts 2020

The Sourdough Project data is finally starting to sing!! The paper, The function and diversity of sourdough microbiomes, is on the verge of being published and I have completed 3 pieces for an album of soundscapes based on the data and findings of the paper.

A little over a year ago, I started working with the Optical Density growth patterns of the 8 most prominent taxa in the 500 starters. Here is a link to the blog post about this idea:

Recently I revised the scale to be a multi-octave expansive scale and aligned the 40 specific growth data points with notes on that scale. Each yeast and LAB (lactic acid bacteria) now is expressed as a multi-octave pentatonic pattern. Here is the final version of String of Yeasts which will introduce the four yeast voices on the album RISE:Sonic Sketches of Sourdough Cultures to be released in March 2021. This piece features K Servazzi, W Anomalus, K Humilis, and S Cerevisiae.

Where the Path Takes Me

Our Waking Lives sometimes flow and sometimes glitch with the main point being “don’t mind whatever happens”. My personal practice is to turn the “oh,no!” into a “aha, what’s this now?” Easy to do sometimes, other times not so much. Immersed in feelings of failure, I sometimes need a few weeks to make that turn-around.

And so it goes in the world of Jude’s Soundlings. Everything is in transition, some stuff is shiny and new, other is old and (semi)reliable! New like the Behringer Neutron with the Make Noise O-Control as sequencer modulator routed through good ole Ableton as harmonics flinger. I am learning so much: I made a filter sweep and some kind of Heinz 57/Swiss Army Knife rack I put together. Got both the FX racks midi mapped to my Novation Launch Control. This is soooo cool! The harmonics shatter, shimmer, echo, melt, propogate and obscure each other.

Sometimes the harmonics from source audio get caught within the Effects Channels. The source stops, but the soundscape lingers on. I was taken aback at first when this happened. Stopping the Source audio track did not stop the sound!? Sonic material continued pulsating in the active FX tracks, so I rerouted other FX Channels to pick up audio from the channel that was pulsating. This sound went on for one to two minutes, while I passed it around through different AAC tracks. Several times I couldn’t figure out how to stop it and had to turn it all down and close the project. I enjoy this mystery and remain curious: recently read something about midi feedback loops! Perhaps that was where we were caught! And they can definitely be played!!

After 8 years of creating electronic soundscapes in Ableton Live using electronic instruments, I have learned a lot about sculpting sound! I enjoy the process of creating the movement of sounds around and through space. Ableton is a wonderful mixing environment. Their plugins are maleable enough without getting into writing program. Now is the time for an expansion! I am hearing a lush carpet of sound in highly structured harmonic streams.

Currently the final analysis of the data for the Sourdough Project is poised to happen. Up to now, my approach to data sonification has involved pitch class to designate the presence of something and amplitude to demonstrate the magnitude of that something. Pretty basic, but it worked for the Baby Lemur Biome Song. ( The Sourdough data is more demanding, and may involve conceptual frameworks based on the data in contrast to using numerical data to specify the sound. Here is the link to work I did with some of the Sourdough Project data using my pitch/amplitude method. ( In this example, the yeast growth can be heard as a sequence of steps illustrating rapid or gradual growth during each 12 hour period. These two sonifications have captured presence, magnitude and growth within time frames. As I study the Sourdough data, these three methods for sonic capture need to be brought together as interactions that change/modulate/meld over time to create Sourdough ecology, which begins with water and flour and ends in smell/taste/feel of the bread itself.

Feeling a bit stuck here at the moment. Must be time to play!!

TRIC Question #1 for 2017

One of the dejacusse/iBoD projects for 2017 is TRIC Questions, a sonic hacking of Terry Riley’s In C or TRIC. TRIC is comprised of 53 rhythmic/melodic riffs based in Nature’s Scale and set against an 1/8th beat pulse. My first pass through this piece was in 2014, when In C turned 50 years old. My approach was more historic then, so I listened to different versions of the piece, read about the composition process and wrote about the initial performances in 1964. Musician friends presented a slice of In C in performance that year, but mostly I explored In C through the Ableton Live DAW using different voices and tempo variations. For more on this, read the blog: My Year In C –here:

During that year, questions continually jumped out of the piece. As I became more familiar with the patterns, they each took on a unique and identifiable voice. Then one day, while looking at the score of TRIC, I saw that this is simply one way these patterns can be put together.

What if each of the 53 packets of tones stands on its own, AND in relation to any and all of the other packages?

Using the patterns of In C as little Lego blocks of sound and putting them together in different combinations has become my approach to “playing” In C.  I want to hear all the sonic possibilities within this musical universe-for what else can you call it? It is not a song, but it makes songs. It is not a symphony, although it has movement and motifs. In C questions all the assumptions we have about in tune and in time when making musical sounds in the world. When we loosen our grip on what we think things should sound like and give our attention to what we are hearing, and what is emerging from our articulations within that hearing – whole other worlds open up. Those are the worlds I want to continue exploring.

My first experiment with the long tones of TRIC was in November 2014. The question was how to use the long tone phrases to express tension and release. To hear the result of this experiment, go here On listening again, I hear the C pulse frenetically undermining any possibility of release. One of the TRIC Questions I have answered is to drop the 1/8th note C pulse. Scoring the patterns precisely in Ableton Live creates a rhythmic underpinning for improvising musicians to play with/against, so the C pulse is unneccessary and unhelpful. Another reason to drop the pulse is that it is an integral part of playing TRIC, and I am no longer playing that particular iteration of these sound modules.

The eight long tone patterns  range in length from 6 pulses to 32 pulses. If all eight modules begin at the same time, there will be a sustained 6 pulse EF#GC [C(add#4)]chord. This could be achieved by triggering all the modules at once. Then, it would be interesting to peal away the patterns till only two remain. Which two patterns will be the final pair that plays this iteration out? One possibility is P30 and P21, which carries the tritone tension through to end. The other pair is P29 and P42, which creates the more consonant C major sound. Let’s try those two ideas. First, we end with P30 and P21. This sketch feels tense throughout. The denseness dissipates, but the tension stays high.

Next, we end with P29 and P42. Here the tritone tension is folded into a more harmonious blend by the end.

I have been so focused on the tritone carrying the tension, that I ignored the tension that half-tone, whole tone and minor third intervals inject into the scape. The final voices in the harmonious sketch create as soothing a combo as exists within this overlayering of fourths and minor seconds and thirds. So while it is soothing, there remains a sense of alertness within the release.

And, for my next trick, I set off that initial C (add#4) chord over and over, each time pealing away different layers to create a longer soundscape. Here is a 6 minute sound piece with five versions of pealing back to two patterns by the end. Each iteration ends with a different pair.

I love the feeling of fireworks exploding into that C (add#4) then the subtle changes that pealing back one part at a time makes to that chord. Then finally, there is a falling off of the expansiveness of the sound field and we are left with just two patterns rocking back and forth. Then – BAM – the C (add#4) explodes again. I love this!

The Gift of Nature’s Chord 

Nature’s Chord is an organizational framework for all frequencies, AND any periodic reoccurrence can be converted to frequencies and studied as this patterned relationship. In his book The Cosmic Octave, Hans Cousto, the maverick mathematician and scientist, demonstrates the formula for converting any periodic function to an audible frequency. He explains that “The period of oscillation and its frequency stand in a relation of inverse proportionality, thus period = 1/frequency and frequency = 1/period. The reciprocal value of a period of time represents its frequency…” You find the reciprocal value of a given period by dividing the number into one. This value is then multiplied by 2 until the number reaches the audible frequency range. Then you can find the tonal correspondence to the periodic function that you just converted.

For example, the speed of light is 186,000 miles per 1 second. “Miles per second” is a dead giveaway that this measurement is a periodic function. (Actually almost any measurement would qualify.) 1/186000 = 0.000005376344086 x 2 to the 25th power = 180.4 hz which is F#/185 hz (-3.6 discrepancy). So the tone for the speed of light is F#. Cousto converts time periods (days, years, etc), planetary orbits, distances between the stars into frequencies. The mathematics point to a potential resonant frequency for any periodic function.

In a recent blog post on The Law of the Octave, I pointed out that our Universe is held together and moved along by vibrations. Even a cursory reading of contemporary quantum physics supports this idea. Nature’s Chord allows access to and influence upon the vibrational Universe. As a painter of sound, a lover of diversity, and a harmonic healer, this is one exciting discovery. This is a way to sonify and present information, bring the resonant frequencies of relationships into harmony, and generally engage with the overall vibration of any situation.

So, I am looking around for periodic data to sonify using the Law of the Octave and Nature’s Chord/Scale. In 11th Harmonic, I used the reveletory research that Dr. Anthony Holland presented in his TED talk on the use of the 11th harmonic in “disrupting ” the cellular structure of tumors. Of course, the frequencies he is dealing with are super high electrical frequencies. When we apply the Law of The Octave, the electrical frequencies can be converted into audible frequencies. Then through the template of Nature’s Chord, we discover that the 11th harmonic is the fifth above the Fundamental Frequency in the fourth harmonic octave. So the 11th Harmonic soundscape begins with those long spacious intervals. I chose four whole tone tetrachords and then paired them with the fifth in the fourth octave. Within the first four octaves of Nature’s Chord lies two more fifths and the third and flatted seventh. When you start swinging these intervals around, more tetrachordal relationships emerge. It is a firework of harmonics when moving quickly, then a luxurious web of sound swaying in the breeze at slower paces. Here is a little excerpt of 11th Harmonic as played on April 4th to reset the time fractal and disrupt the stuck energy behind war and violence.

And, sure enough, Trump bombed Syria. (And the butterfly flaps its wings.) The 11th Harmonic disrupts and moves the energy without any particular outcome except dislodging and moving the energy. (Which is why Dr. Holland does not say the 11th harmonic “cures” cancer. It disrupts the integrity of the cancer cells.) And, at the same time, Nature’s Chord and the Acoustic Scale express beautiful, harmonious sonic relationships, within which the change is happening. That is the vibe! As these magical relationships are expressed with open-hearted loving intentions, entrainment happens and the vibration rises up. And, it happens in mysterious ways. Entrainment is alot like God, like Love.

While I was writing this post, Trudie asked, “Did you know that the Hindu creation myth says that the world was created through sound?” No, I did not! Research revealed several Hindu creation myths – hooray for multiple potential beginnings without needing one to be right!  Here is one of the creation stories from Hindu mythology.

Before this time began, there was no heaven, no earth and no space between. A vast dark ocean washed upon the shores of nothingness and licked the edges of the night. A giant cobra floated on the waters. Asleep within its endless coils lay the Lord Vishnu. He was watched over by the mighty serpent.

Everything was so peaceful and silent that Vishnu slept undisturbed by dreams or motion. From the depths a humming sound began to tremble, Aum. It grew and spread, filling the emptiness and throbbing with energy.

Aum, or Om

The night had ended, Vishnu awoke.

History is, in part, the periodic oscillation of humanity falling asleep into the larger, darker dream and then awakening into the light of self-awareness. We are riding the wave of an awakening time right now. Pay attention to what and to whom you give your attention. Our moment -to -moment awareness is our most valuable currency.  Do not squander it on guilt and sacrifice. Do not squander it on exploiting and manipulating others. DO, yes, DO give your attention to all that is in your present moment. Give it to the joy, beauty, harmony, pain, suffering and dissonance that is within each moment of our existence. Breathe. Wait for instructions. Remember vibration. Dance and sing, move and vocalize however you are able. (In the head works, too)

Allow the awakening to unfold!
