Comparative Case Study in Respective Design Choices Eliciting Heightened Multisensory Experience Within Contemporary Concert Performances

In the following essay I will examine and compare the authored design choices present within three recent concert performances of contemporary live music performance groups giving clear consideration to the heightened multisensory experience of the audience. I have selected three performances that I personally attended from 2010 to 2016 that each employed distinct and strategic sensory design choices to elicit heightened experiences within comparable venue spaces and patronage.


Autechre - Hifi Bar (Melbourne) Saturday 29th May 2010

Autechre have famously performed their live shows with all house lights and lighting intentionally disengaged for most of their career. This is an authored design choice intended to focus the audience’s attention on the sound and make them confront the effect of their visual bias. This is not simply the absence of light, Autechre have employed minimalist design considerations all throughout their work over their entire career. Their live show is no exception, the complete absence of light is as much a visual design choice as the deployment of negative space within minimalist design as is silence within minimalist sonic compositions. The darkness is the visual element within the show. By enforcing the absence of light within every performance the audience is forced to confront the impact of visual bias has on both performer and audience.

Interestingly, the live experience of this enacted design principle is as polarizing as the group’s perpetually mixed album review scores.
Observing the behaviours of the crowd, I noticed a considerable amount of the audience seemed disoriented and mobile - over the duration of the performance moving around the room and facing in different directions, talking amongst themselves facing away from or at right angles to the stage - clearly unsettled or otherwise disengaged. The remainder of the audience were hyper focused on the sound, highly engaged and clearly having individual experiences or shared with small groups. The audio recording of the performance is a mix of the desk audio and a microphone capture that was placed within the crowd. At certain points in the recording conversations between overexcited patrons can be heard discussing their perception of the sound, at one stage describing it as, “like an aural painting” and, “it’s like they’re throwing noise at each other” in between guttural exclamations of delight and hysteria. For some of the crowd clearly this was a highly visual experience.

“If people have their eyes shut that’s good for us, and we prefer that to visuals. If you have amazing visuals but the music’s no good, then you’ve channeled your energy in the wrong conduit. Without lights people go off at more of a tangent, and shift to another parallel. The club space, if it’s dark and a bit foggy, with a console of twitching lights – that’s the ideal venue for us.” - Rob Brown (musicomh.com, 2010)

The disorientating elements of the performance are not exclusively that of the lighting choice, but also the non conformity of the rhythmic and melodic structure of the music itself. Expressive atonal, microtonal or entirely textural elements were imposed over firstly very repetitive simplistic rhythmic structures, then over very non repetitive complex rhythmic structures. The movements between these structural changes gave the sense that they were improvised and not following conventional metering conventions and other musical grammar that most audiences are conditioned to synchronise their tension/release responses to.
From my personal experience I estimate is that approximately 40% of the crowd were disengaged for most of the performance for the above reasons. I found myself disengaging during the early moments of extreme repetition, but I used those moments to observe the crowd. I found lack of conventional metering and musical grammar to be highly immersive and the absence of light to absolutely assist with the immersion.

Physiologically, the utilisation of the frequency spectrum and stereo spatialisation were the primary agents of action for an otherwise predominantly cerebral experience. A paradoxical sensation of perpetual tension counterbalanced by either comforting tones or swaying rhythms akin to the sensation of travel by boat, being pummelled by waves. Many rhythmically dense moments had the sensation of being a pinball, the polyrhythmic interaction between triplet and non triplet quantized percussion colliding against each other in a paradoxically half mechanical half relaxed groove again arising in an ongoing emotional flux of tension and release dispersed at the micro level within the bar, as opposed to the conventional compositional macro level across the traditional 8 or 16 measures.

Autechre are uncompromising in their artistic vision, in spite of their own fanbase. It is difficult to declare that the alteration to the described disorienting elements of their performances would be anything but a compromise. Disorientation is key to the appreciation of their work, as is the individualised audience experience. One might critique the repetitive compositional elements or the long stretches of spatialised atonal textures in aid of keeping the music conventionally engaging and assemble the crowd with more unifying moments of cheering - but this would be to misunderstand the key elements of what is distinctive and perplexingly sublime about the sensorial experience of Autechre’s performance work. These long stretches function in the same fashion as the lighting, the absence of familiar musical grammar forces the audience into individualised experiences either rich, engaged and imaginative, even contemplative - or disengaged and devoid of interest. For my money, I wouldn’t trade those rich individualised experiences of inner dialogue for want of a more unified audience experience. It is exactly the sublime and challenging moments of an Autechre performance that brings into question the fundamentals of everything one thinks one knows about music. For some this is a claustrophobic experience, for others liberating.

Academically, there is not a wealth of literature devoted to the analysis of the Autechre live experience aside from a few reviews from old magazines. Fundamentally this is a highly individualised experience that either works for you or it doesn’t - much like their discography. A fundamentally idiosyncratic and enigmatic group, Autechre’s design elements remain largely untouched by serious technical analysis within academic spheres. If any parallels were to be drawn to existing design concepts it would be to the tenets of minimalism, in spite of their apparent maximalism. Within minimalism the strokes or actions are equally important as the inaction. This is ever present within their live performance, where drawn out moments of inaction where generative rhythms and evolving textures aren’t imposed on by the performers leading to moments of contemplation and reflection within the engagement to the present sensorial moment.


Amon Tobin’s ISAM - Palace Theatre (Melbourne) Tuesday 5th June 2012

To many, Amon Tobin’s ISAM concert tour heralded a new age of multimedia concert performances - the spectacle of the custom fabricated geometric structure being projected onto from multiple projectors playing a perpetually changing array of choreographed and audio reactive imagery in conjunction with a sonically and dynamically rich score was truly a new frontier for live performance and executed at an extremely professional level. Indeed, this was the work of an entire production team headed by both V-Squared Labs & Leviathan creating customised software and visual elements and a four person set design and construction team.

In stark polar contrast to Autechre’s approach to live performance, ISAM was a maximal visual spectacle, meticulously choreographed and rehearsed down to every last pixel designed to captivate and overwhelm the visual senses. Even the performer was hidden away inside the set, only being made visible during a few moments during the performance and very much dwarfed by the whole spectacle. It is in this sense that there is a parallel between Autechre’s obfuscation of performer identity behind the grand spectacle of the show itself. Though their response was entirely different. When the spotlight became pointed at Tobin, he attempted to match the grandiosity of the set with highly exaggerated performance gestures as if to communicate with the audience that he was indeed in control of this gigantic spectacle before retreating back into his small cube and becoming once again obscured from the audience’s vision. For some, this was an exciting moment. For others including myself this felt like an overcorrection. An akward moment that attempted to counterbalance the extremely scripted nature of the performance with a moment of humanity - executed through highly exaggerated and most likely mimed theatrical gestures.

Though for many this would have felt like the next evolution of live music performance, when considered from this perspective it is in actuality further removed from this status than it approaches. The visual spectacle and scripted, choreographed nature of the performance places it closer to the domain of theatre and film. Each audio track of the performance had an accompanying visual routine, computer generated elements primarily acting as a kind of audio synced pantomime. My memories of the show were not of the sound, but of the visuals. The performer is almost incidental - exemplified by his almost purposeless existence hidden away behind the set. The kineticism is entirely present within the highly dynamic and syncretic visual elements, not in the performance of the sound, in spite of Tobin’s attempts to be appearing to do so.

“So I started storyboarding it and decided it would make sense if the whole thing was a kind of physical journey, so the structure could be a vehicle. It came from that. It is an adolescent fantasy, it is sci-fi. At the end of the day, it’s not trying to be high art. It’s a visual soundtrack to a piece of music. It doesn’t have to be an incredibly deep story full of metaphor to do that; it just has to be evocative and imaginative.”
Amon Tobin (inthemix.com, 2012)

My experience of ISAM in concert was that of most, I was genuinely amazed at the visual spectacle and engaged by the accompanying score - at times even losing awareness of the sound due to the sheer scale of the visuals. In fact, at one visually intense moment a girl in front of us had a seizure and fainted that we helped to take to the first aid. A reminder of how truly gratuitous this show actually was. Emotionally and physiologically this concert didn’t really move the needle much out of the domain of sheer amazement. In fact, physiologically I didn’t really experience much at all. Like most people I was frozen to the spot for the whole performance. With so much visual kineticism on stage it was more like watching a tennis match or a film than a dance party.

There were emotional swells elicited from the crowd during mutual exclaims of “ooh’s” and “aah’s” and a genuine feeling that the entire room had been taken back to a childlike feeling of wonder, exemplified and prompted by the subject matter of some of the visual routines like blocks falling down stairs, space ships, robots and the like. But there was a fundamental separation between audience and the spectacle that interfered with immersion. Where I felt like the performers were as much part of the experience as the audience with Autechre all together in a dark room, I felt like even Tobin was separate from the performance - that we were all watching this spectacle run its course from start to finish with Tobin making the occasional cameo.

The history behind big budget multimedia shows is a recent one - acts like Daft Punk and Muse are arguably better known for the work of their production team than their music. As the industry has shifted towards live music revenue over album sales the necessity for spectacle has driven more high profile acts to adopt gigantic multimedia set pieces and routines to their shows in order to provide a new heightened sensory experience for their audiences to add value to their shows. In almost all cases however, this never extends thematically or conceptually beyond the realms of shock and awe.


Sunn o))) - Max Watts (Melbourne) Wednesday 16th March 2016

Somewhere between the pantomime gratuity of ISAM and the reflective min/maximalism of Autechre lies the live performance aesthetics of Sunn o))). There are rules to a Sunn o))) performance. The sound pressure levels will always be extreme. There will be enough fog from the smoke machines to entirely obscure your vision for most of the performance. There will be men in cloaks on the stage.

The experience of a Sunn o))) performance is gruelling, harrowing - but rewarding. The sensorial elements of the extreme amounts of fog and decibels coupled with the over capacity sold out show attendance ensures a perpetual state of tension - for some, sensorial claustrophobia. The inescapable nature of cumulative body heat, the fog making it hard to breathe and see or smell whilst being entirely overwhelmed by the extreme sound pressure levels leads inevitably to a state of pure submission or inner turmoil. Rather than the musical accompaniment and physical performance assaying to alleviate this tension through energetic composition or gestures, instead both the music and the performance is long, slow and drawn out to a glacial pace that heighten the rest of the elements to critical levels.

A Sunn o))) performance is as much an exercise in brutality as it is in inner reflection and contemplation. Much in the same modality as Autechre’s strategic sensorial disorientation eliciting highly individual and imaginative responses and inner dialogue - Sunn o))) pummels its audience fixing it to the spot and choking it like a large snake over the course of an hour, forcing each member of its audience to slow down and entirely abandon their thoughts in a macabre, confronting guided meditation. Shortly through the performance when thoughts of reprieve begin to emerge, as if by pure telepathy instead of the band changing the tone to build upon and away from the punishing start - the entire band leaves the stage leaving only the vocalist. Sonic minimalism pushed to an even further extreme. Given all that has preceded it, the experience of having everything removed to pure chanting is as close to true sonic existentialism as you could get. You could hear a pin drop in that place. Slowly you become aware that in fact the foggers have stopped and you are in a room full of utterly silent people staring up at a man intermittently growling incomprehensible lines of text illuminated by a single spotlight. It is almost biblical. You can hear exactly when the decay of the natural room reverb ends, a silent breathless eternity passes between each growling chant. When the band does eventually return and begin to layer rich, dense textures underneath once again you appreciate it, you actively become immersed in it. You relish it. For me, I chose this moment to close my eyes and yield completely. The experience was phenomenal. My senses were entirely distorted. Firstly the sensation of being in a crowded room were entirely inverted - this punishing perpetual sensation of being surrounded by fog, people, sound all of it entirely inverted. I had the distinct sensation of being in an extremely large warehouse, alone. This gave way to paying attention to my vision - remaining aware of my closed eyes and being acutely aware of the waves of sound hitting me my perceived notions of the dimensions of the room I was in became distorted and angular in relation to the frequency content and phase relationship of the distorted textures I was hearing. Let me now make clear that this was all under the influence of a single overpriced heineken.

When I finally opened my eyes I was greeted with the visage of the singer now wearing a dress and crown covered in broken mirrors and wearing lasers on each finger of both hands - posing dramatically. I nearly burst out in hysteria. Total immersion breaker. Unfortunately from that point forward I struggled to regain the complete immersion I experienced earlier in the performance. The mirror/laser costume and posing remained a feature until the end of the performance and never felt anything other than completely ridiculous. As if men chanting in robes and playing detuned guitars at ear damaging levels through more fog than a british winter morning wasn’t for some reason already utterly ridiculous.

At this stage I could discuss some of the history of the ritualistic and thematic elements that inform the Sunn o))) show, but ultimately that isn’t what made this a distinct, powerful experience for me. It was purely the extreme manipulation of sensorial elements that elicited such a powerful response. It was not through ritual theatrics or pantomime that engaged me, it was the confronting and punishing amplified minimalism that directly engaged me and led to some inner moments that I imagine are akin to lucid dreaming or deep meditation - having never been successful with either.

If there is a throughline to draw across all of these experiences, it is that perhaps the most powerful live sensorial experiences come not from what is added, but what is removed. The audience is challenged to engage on the deepest level when they first overcome their natural tendency for expectation - when expectation is perpetually challenged or subverted or beaten into submission the mind is liberated from the passivity of expectation. For some that becomes a catalytic moment of disengagement, the mind wandering from the moment. For others it allows the mind to wander in an altogether different modality. Heightening senses through the amplification of single elements like darkness, air density, sound pressure levels all elicit far more challenging and deeper experiences than a dynamic visually stunning set piece. A scripted multimedia pantomime may engross an entire crowd through scale, but ultimately can only be experienced at arms length. The strategic manipulation of the very sensory elements that make up the room housing the performance can be employed for much greater effect - though at the risk of the disengagement of some of their patrons.

COMM2591 - HMsEx Week 1 Vigilance :: Week 1

Vigilance (Psychology)

In modern psychology, vigilance, also termed sustained concentration, is defined as the ability to maintain concentrated attention over prolonged periods of time.

Vigilance, alertness, or sustained attention: physiological basis and measurement
B.S. Oken,a,b,* M.C. Salinsky,a and S.M. Elsasa
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2865224/

Abstract:
Vigilance is a term with varied definitions but the most common usage is sustained attention or tonic alertness. This usage of vigilance implies both the degree of arousal on the sleep–wake axis and the level of cognitive performance. There are many interacting neural and neurotransmitter systems that affect vigilance. Most studies of vigilance have relied on states where the sleep–wake state is altered, e.g. drowsiness, sleep-deprivation, and CNS-active drugs, but there are factors ranging from psychophysics to motivation that may impact vigilance. While EEG is the most commonly studied physiologic measure of vigilance, various measures of eye movement and of autonomic nervous system activity have also been used. This review paper discusses the underlying neural basis of vigilance and its assessment using physiologic tools. Since, assessment of vigilance requires assessment of cognitive function this aspect is also discussed.

VART3492 :: Advanced Studio Technologies 2 - Rhythm Design notes





*To achieve 16 pulses over 8 plinths, each sequence plays twice



One of the most effective ways to add spice to rhythms by means of syncopation is to use it in such a way as to create what might be called a slight temporary confusion or cognitive insecurity, or metrical dissonance, or what Neil McLachlan calls a gestalt despatialization. In the case of 16-pulse timelines, which necessarily have four strong fundamental four-pulse beats felt at pulses 0, 4, 8, and 12, a gestalt despatialization can be introduced by first misguiding the listener into perceiving and cognitively predicting a sequence of three-pulse duration intervals. For this to happen there must be at least two initial IOI’s of duration equal to three pulses. This means that the first three onsets must occur at pulses 0, 3, and 6. However this is not sufficient. To achieve the gestalt despatialization the last IOI of the rhythm must have duration equal to four units, and hence be determined by onsets at pulses 12 and 0. In this way the rhythm ends with two clear fundamental four-pulse beats.

VART3492 :: Advanced Studio Technologies 2 - Bjorklund Algorithm & World Music


A new family of musical rhythms has been described, called Euclidean rhythms, which are obtained by using Bjorklund’s sequence generation algorithm, which has the same structure as the Euclidean algorithm. It was shown that many rhythms used in world music are Euclidean rhythms. Some of these Euclidean rhythms are also Euclidean strings [11]. The three groups of Euclidean rhythms listed in the preceding section reveal a tantalizing pattern. Those Euclidean rhythms that are also Euclidean strings (the first four of group one) are favoured in classical, jazz, Bulgarian, Turkish and Persian music, but are not popular in African music. The Euclidean rhythms that are neither Euclidean strings nor reverse Euclidean strings (the first two of group three) are used only in subSaharan African music. Finally, the Euclidean rhythms that are reverse Euclidean strings (the second group) appear to have a much wider appeal. Finding musicological explanations for the preferences apparent in these mathematical properties raizes an interesting ethnomusicological question. The Euclidean strings defined in [11] determine another family of rhythms, many of which are also used in world music but are not necessarily Euclidean rhythms, as for example (1221222), an Afro-Cuban bell pattern. Therefore it would be interesting to explore empirically the relation between Euclidean strings and world music rhythms, and to determine formally the exact mathematical relation between Euclidean rhythms and Euclidean strings.

VART3492 :: Advanced Studio Technologies 2 - Further Polymeter research




Let us begin with a look at the music of Steve Reich, specifically one his seminal works, Drumming (1970-71). The piece was composed over the course of roughly one year following Reich's return from Ghana, where he studied drumming with Ewe master drummer Gideon Alorworye2. Reich recorded each lesson with Alorwoye and afterward played the tapes back at a slow enough speed so as to be able to transcribe the individual patterns. By doing so he noticed that different instrumental patterns present in Gahu music, although rhythmically compatible either by a simple or polyrhythmic relationship, were not bound by any sort of attachment to the first downbeat of each measure. 
The way in which Reich has established the measure lines for each pattern in his transcription is a clear indication of his perception of meter in this type of music. Rather than simply dropping all of the patterns into 4/4, Reich maps the relationship between each instrument in a polymetric, albeit very closely related, way. The top gong gong line is an eight quarter note long phrase, whereas the rattle part directly below is exactly half the length at four quarter notes. The third line, a one quarter note long kagan pattern, is basically the tactus of the whole piece but displaced by one eight note. The bottom three lines are all four quarter notes long but displaced by one and a half quarter notes (kidi), one quarter note (sogo), and a sixteenth note (agboba), respectively. This rhythmic displacement is where we start to see the influence of Reich's time in Africa on his compositional approach to Drumming. The variability of the displacement is crucial to our understanding of Drumming and how the underlying process of rhythmic phasing works. 






Midi transcription of 'Drumming'



The sense of becoming fixed in time (to paraphrase Gretchen Horlacher) frequently goes hand-in-hand with the sense that two separate motives are actually fused into a single pattern. Put another way: because displacement dissonances do not challenge our sense of metrical periodicity (though they may challenge our sense of downbeat), two ostinati that form a grouping dissonance are far more likely to be differentiated as separate motivic strains than are two ostinati that form displacement dissonances. By intermingling these two types of metrical dissonance — often willy-nilly — Adams projects a freer relationship between two textural lines. This is one feature that sets his minimalist technique apart from that of Steve Reich or Michael Torke, who generally don’t oscillate between metrical dissonance types quite so readily.

VART3492 :: Advanced Studio Technologies 2 - Polymeter Studies



Basic Polymeter studies & Rhythmic Displacement:
Asymmetric lengths force pulses to shift around each other.




(Equal measures appears to shift as odd measure begins a new cycle, we perceive the odd measure to be in the foreground (figure) as it contrasts prominently against the constant equal measure that appears more background (ground))

7/8 (top) against 8/8 (middle: downbeat/kick, lower: downbeat/snare)
 - taking 8 measures to resolve



9/8 (top) against 8/8 (middle: downbeat/kick, lower: downbeat/snare)
 - taking 10 measures to resolve



Using mixed meter to force resolve around another meter (in this case 4/4)



"The difference between metric dissonance and the overlay used by Meshuggah lies in the structure of repetitions within each rhythmic layer. Whereas the rhythmic layers of metric dissonance involve recurring, uninterrupted patterns, Meshuggah uses asymmetric repetitions in the guitars and bass part resulting from mixed or changing meter. Krebs points out that even metric dissonance “invariably involves some alignment of attacks, the alignment occurring after a number of pulses generally determined by the product of the cardinalities of the interpretative layers” (Krebs 1999, 31)."

http://www.britannica.com/art/isorhythm

isorhythm,  in music, the organizing principle of much of 14th-century French polyphony, characterized by the extension of the rhythmic texture (talea) of an initial section to the entire composition, despite the variation of corresponding melodic features (color); the term was coined around 1900 by the German musicologist Friedrich Ludwig.
A logical outgrowth of the rhythmic modes (fixed patterns of triple rhythms) that governed most late medieval polyphony, isorhythm first appeared in 13th-century motets, primarily in cantus firmus ortenor parts but occasionally in other voices as well. Abandoning all modal limitations, the isorhythmicmotet of the 14th century managed to derive decisive structural benefit from the systematic application of given rhythmic patterns without the inescapable dance associations of its 13th-century predecessor. The first great master of the isorhythmic motet was Guillaume de Machaut (c. 1300–77), but instances of isorhythm occurred as late as the early work of the 15th-century Burgundian composerGuillaume Dufay (c. 1400–74). As an analytical concept, isorhythm has proved valuable in connection with musical practices quite unrelated to those of the European Middle Ages—for example, peyote cult songs of certain North American Indian groups.

VART3491 - Advanced Studio Technologies :: NeuralOSC

NeuralOSC is prototype interface for the sonification of live brainwave data that uses Neural Feedback to entrain both focus and relaxation in a gestural musical environment. The user is coaxed to engage with musical stimuli generated from their own neural oscillations in real time from a single dry electrode interface that communicates wirelessly via bluetooth into MaxMSP. The user's focus is entrained through the articulation of filter movements, pitch and timbral modulations, while a state of relaxation is used to lower the amplitude and tonal quality of other elements. NeuralOSC is an immediate and engaging way to explore neurofeedback and an interesting environment to play music!

VART3510 - AkE Internship :: Final Report Responding to Host Feedback

My internship experience gave me insight into the research application process and the speed at which the process to undertake academic research occurs. Darrin provided guidance in shaping the research and vital assistance with networking within the University and the protocols involved with preparing a research proposal. The process felt fluid and I was given freedom to set my own research goals which we developed in tandem. I was given the opportunity to work toward a postgraduate level of academic inquiry and developed some of the knowledge and skills required to undertake further research. Having had no prior experience with academic research projects I feel this is excellent preparation for the future, especially with the scope that this initial study may lead to further research.

Darrin and I have similar interests artistically so thankfully at all times I felt we were approaching the same goal in terms of field of inquiry - I think we are both genuinely excited to pursue this research topic. Darrin's own experience and knowledge generated from his postgraduate studies has been very beneficial. Along with my own literature research, his recommendations of texts have given me an ideal knowledge base to become familiar with when looking at the area where music, sound and neuroscience intersect.

The research project is scheduled to occur next semester where I will continue to gain experience in undertaking the research with participants off campus at Monash and learn the process of publishing the findings of which my name will be attached.

It is my intention to apply for the honours program and eventually move to PhD. This has been a great experience in moving toward this direction for the future.

Comments from Supervisor:

Jay’s original research project was to explore how binaural beats entrain particular brain states, with a view to collecting EEG data to control motion simulation systems on which the audience member would be seated. Through preliminary discussions it was decided to separate the research elements from the artistic outcomes – as the latter had the potential to confound the data through both their experiential complexity and the inherent recursion of the system.

In preparation for a lit review, and in the process of discussions with other departments, the existing data was surveyed and it was decided that such a seam of pure research stood to be too dry to explore within a fine art context. In order to find a meaningful relationship between sonic practice and psychophysiological exploration a new topic was considered – whether brain patterns would be substantially different for sound art versus traditional musics. The question at its core was whether genres such as noise and electroacoustic composition might be processed more as an environment, and not engage the language centres in the brain which have been linked to tonal music grammar.

Jay’s internship was designed to give him exposure to academic research practices and procedures. The key outcomes have been

  • Research into generating technical access for more professional equipment
  • Exploration of different departments at uni
  • Preparation for lit review
  • Exploration of ethics procedures
  • Experiment design
  • Survey design
  • Technical research (EEG)

The tests he will be undertaking have been designed, and an ethics application is in process with CHEAN. Work with the experiment will continue beyond the internship.

VART3459 - Production Strategies :: Final Essay

I have predominantly spent undergrad exploring procedural driven technical projects, developing project specific design objectives and undertaking them systematically. I have really enjoyed the departure from working purely intuitively and developing a clear line between concept development stages and the execution stages of a project. The process of reflection in each task has helped me realise this and build upon it.

My coursework has acted as focal points to teach myself electronic engineering, computer programming and develop music theory skills. Rather than take the corresponding electives I developed all of these skills within arts based practise. It is only now that I find I have to account for this. Unless I have an artistic objective to employ a technology I do not find the process of learning that technology to be engaging in the slightest. Objective oriented learning in conjunction with concept development has proven to be an effective strategy.

In terms of expression, I have found arts based practise to allow more breadth in scope for following conceptual threads in the articulation of sonic design opportunities. Not being tethered to a summed stereo file is liberating to say the least. Of course the scope of stereo sound is vast, and the merits of being able to translate ideas working to a reductive format are numerous - but stepping outside of those constraints in an artistic context has been akin to adding a third axis in cartesian space.

At this junction I'm forced to consider why I am drawn to an installation arts practise and assess how divergent it is from my musical practise. Over the course of my degree I've neglected music almost entirely, I'm not convinced this is accidental. I'm compelled by the research driven component of installation design and the ability to articulate ideas spatially. The spatiality of stereo sound compositions is almost entirely psychoacoustic, I have a need to investigate tactility and materiality in a sonic context. I feel that one practise informs the other. The perspective from experimenting in an installation context has deepened my understanding of sound outside of a musical framework.

This course in particular has required me to reassess and clarify design objectives within my music. Early on I created a laundry list of design elements I am still yet to fully investigate. Elements of my early music were driven by the exploration of chaos and order, steganography, esotericism and temporality. Later I allowed myself to be indoctrinated by conventional compositional expression and standardised production techniques leaving most of this behind. I became tired of music. Installation work allowed an avenue to continue exploring these concepts from a new perspective.

This is perhaps why I selected a project for this course that is musical in nature, but expressed in an installation context. One element I identified early in the course that I wanted to explore and had yet to in academia was algorithmic composition. My motivations behind this are not technical. Chaos and order remain the primary elements that fascinate me in music. Being able to construct and permutate complex rhythms is integral to reconstructing the moments in music I find the most satisfying. To clarify, I have no interest in creating musical algorithms in the sense that renders the only performative gesture as a single catalytic keystroke. To me that is as fascinating as a screensaver. Or a pre-rendered composition. The actuation of process is identical.

To me, the performative possibilities of algorithmic composition are exciting. There is a gestural limit that greatly reduces the improvisational potential of live electronic music. This chasm is primarily what removes electronic music performance from the immediacy and excitement of live instrumental music, what is lost in sonic potential is gained in the immediacy of performance and the range of improvisational possibilities. I guess I like to consider rhythm as a sound object in the way a drone musician considers tone. The ability to manipulate temporal sensation through dynamics and density. My feeling is that drone and noise remain the dominant modes of improvisational electronic music performance purely because of the immediacy of the interfaces used and the speed with which humans can interact with them. I would like to see the microtonal complexity these performances be seen in an improvisational, gestural rhythmic context.

So why not a folio of music compositions? I don't find it to be a suitable way to conclude my degree. I came here to find and explore new modes of expression for sonic concepts. I intend to graduate having created a central installation work that may lead me to residency opportunities and post graduate studies. I am very interested in pursuing deeper academic enquiry into sound based research. Despite having to sacrifice the performative nature I outlined above, I wanted to find a way to incorporate algorithmic composition into an installation piece.

My proposed piece "Elements" explores the nature of matter and meter. 8 metal bowls of ice are arranged in a 1 metre radius each suspended above glass jars. Actuators are attached both the bowls and the jars as euclidean divisions of tempo are dispersed polymetrically around the circle. As the ice melts to water the glasses fill, gradually altering the resonance of each strike.

The title of the piece references Euclid's Elements, the famous thirteen book treatise by the Greek mathematician which contains his life's work.

Articulating this work electro-acoustically allows me to explore elements of materiality and visual aesthetics, elements that are not primary considerations when working digitally. The removal of almost limitless freedom to sculpt sound in the digital domain has forced me to consider sound much more maturely. I am enjoying this. To be restricted to minimalist sound palette with no post processing forces me to consider how sound will react within the space. There is something liberating about this. Being able to step back and just let sound exist. Just using a small set of acoustic parameters to alter the sonic characteristics - that on a nano-level are somewhat aleatoric.

Listening to the Reflection of Points

Toshiya Tsunoda


In order for a sound wave to be heard as sound, various physical and qualitative attributes must interpose.
Using the reception of footsteps as metaphor, Tsunoda’s installation features a table with small speakers and corresponding numbers of everyday objects. A sound wave moves through the speakers at fixed intervals, exploring the changes a sound wave makes to a fixed space when it progresses towards objects, collides with them and is reflected. As such it becomes an index for the fixed space, and generates changes as it moves. These changes are perceived by the observer and appear as occurences. Reception of these occurrences means that the state of the space has been grasped, thereby completing the change generated.
Toshiya Tsunoda’s work is internationally recognized for its unique and conceptually rigorous take on sound installation and field recording. Born in Kanagawa, Japan in 1964, Tsunoda received his MFA from Tokyo National University of Fine Art and Music.

Empty Vessels

ALVIN LUCIER

Empty Vessels (1997) belongs to a series of works in which Alvin Lucier studies the resonance characteristics of the smallest interior spaces. He has placed eight glass water containers and vases on pedestals along the space’s south wall. Microphones are placed in the openings of the empty vessels, and each is rooted through limiters to speakers. The eight loudspeakers are positioned exactly opposite, along the space’s north wall. The amplifier in each microphone-loudspeaker system is selected in such a way that each strand of feedback is marked by the resonant characteristics of the respective vessel. This creates a controlled feedback field of resonant tones and their interferences in the ANX gallery space. When entering the field, the visitor disrupts the delicate balance of the system, creating new feedbacks with unexpected frequencies. Even a small head movement is enough to hear a multifaceted, fluctuating spectrum of pitches. Realization: Nicolas Collins and curator: Carsten Seiffarth. Read more about Alvin Lucier and his program in Oslo during the Ultima Festival.

Arduino circuit with waterproof temp sensor, photoresistor and audio output



arduino + temp & light sensors in situ with piezo contact mic triggering generative tones and modulating live audio feed in maxMSP







Reflection: Best I could do given the circumstances. Notes for the future, generative site responsive works should feel more emergent of the space. We also should have directed people to enter one at a time. With a longer installation the body heat of the people would have altered the tone more. I felt the sounds generated were a decent approximation of the space. It felt more like a score than a sound design piece, but I think ultimately that was the intention. It was performed, but by a computer and electronic sensors.

Group task preparation

Group is having difficulty selecting a space. Oli found a space in Trades hall.

We all seem to want to use a confined space. Oli suggested using arduino.

Ash wants to make it comedic/performative. I'm not sure I can contribute to that.


Backup space is the ladder area near the toilets in building 14, can we access it?

VART3510 - AkE Internship Journal Week 6 :: Further refinement & CHEAN

Darrin has advised me of the College Human Ethics Advisory Network [CHEAN] and the process required to authorise research involving participants. He has advised me to outline any potential risk factors of the test design.

I've made note of the following considerations for our application to CHEAN:

*Volume - Decibel level /SPL using Earbuds 
We can control for this using a suitable volume

*Dry electrode sensor considerations 
Participants need to informed that they can not have any cuts or abrasions in sensor area, jewellery, metal plates in skull, electrical oversensitivity, pacemakers.


*Psychological issues 
Controllable, we will require that participants cannot undertake the research if psychological issues are present


Also, after filling out the CHEAN application form: Ethics Checklist for Negligible Risk Projects - questions 1, 2 and 8 required to be answered YES, requiring the Ethics Checklist for Low Risk Projects to be filled.





In the Ethics Checklist for Low Risk Projects I only identified one question that may prevent us from applying under the Low Risk category. Under administration of other substances or devices I ticked YES on the basis that we will be using the EEG device on our participants. Darrin is going to contact CHEAN to ascertain whether this does disqualify us from the low risk category.



We also decided to restrict the audio stimuli to two sources. We are both fans of the contemporary electronic noise musician Merzbow, we opted to compare and contrast the neural oscillatory response from a single piece by Merzbow and a single piece by Mozart. Simplifying the list of auditory stimuli to be played to the participants allows us to avoid having to tightly control the timbral, historical, dynamic elements and energy levels of the compositional stimuli. This allows for a piece by a contemporary electronic noise musician to be incorporated into the research.

This is also under the suggestion from Darrin that the most opportune pathway with research is to begin with broad strokes and follow up with detail in subsequent research - which feels much more suitable.



Refined research proposal:

Observation and recording of comparative brainwave activity changes in response to musical and noise based sonic compositions in order to examine whether a conventional musical framework is a significant component in the neural response to composed sonic stimuli. 


Participants will be played a single piece Mozart followed by a single piece by Merzbow. Responses to the stimuli will be measured via EEG over the duration of the composition after a baseline response has been recorded. Respondents will also be surveyed via questionnaire following the experience.



I have modelled our Participant Survey after a previous study that Darrin had undertaken.
