I have been recording the sounds that the sculptural components collect from their surroundings and reprocess within their space. This leads me to think about how sounds might behave when coming from within.
The final work will be a complex of interconnected internal spaces. How might these behave? How will this behaviour be affected by how components are connected? Is this relevant to the overall thesis; might this be an effective layering of meaning; confusing the issue; better used in some other context?
I continue to experiment and think about future works as the process of making evolves.
Gareth Jones, in his essay, describes the historical changes in the relationship between sculpture and sound. This dichotomous tension is straddled by Gil’s work in Sonic Plasticity proposes the use of sound as a malleable material – one that can be stretched in all dimensions, encompassing height, width, and depth, with curves, edges, and changing geometries. His Aural Fields and Resonant Bodies combine physical structures set to vibrate, creating geometric fields of sound perceivable in space with edges and form.
This is an interesting field I am currently investigating with respect to the final proposal with respect to sculptures. I am not proposing to do the same sort of thing but Gil’s work does have correspondence with how I see sound as creating a physical entity in itself.
My idea is to counterpoise the readability and sensuality of the solid pieces with the pure perception and sensuality in another modality of sound. I am concerned about the cancelling out of one another: should solid sculpture reside in silence, should sound be disembodied? These are questions I intend to explore and aim to resolve in some way. The use of digital interactive devices is something I have been working with enabling an element of audience interaction. But then again, the work in silence also speaks of itself. This is an interesting area of empirical research which needs a trial and error, or heuristic, approach.
What struck me when I got the Arduino board was, how small it is, how small all of the things are. And that means, that they will be far less obtrusive than I had previously thought. And seeing how easy it is to work with I look forward to learning a great deal.
The next step is to get to grips with the coding. Fortunately there is a lot of help on the web and even if some piece of code is not exactly what I need, I feel much more confident to be able to tailor it to my needs.
How do I feel about using digital sound in conjunction with sculptures? I have always felt there is an equivocal relationship between sculpture, or statuary to be more precise, and sound. Is a statue not meant to be silent, to be contemplated without the distraction of noise?
But what if the sound comes from within, trapped, allowed a small breathing hole to reach one’s ears, fingertips, barely audible, sensed; a sound that is neither music nor the result of some kinetic accident? I see the sculpture as the receptacle of its own soul, the embodiment of what it is in its nature to be gently radiating outwards, translated into vibrations seeking connection.
There is of course an element of humour in all this, for it to be otherwise would be melodramatic and to what end: humour can be poignant, questioning, engaging, cathartic. All I know is, I go with where the work takes me as it also follows me.
The object of my research at this point in terms of electronics, coding etc, is to control the audio output of a sound file using Arduino and an active IR sensor and that this system should be fully automated and self starting using a Raspberry Pi coded (perhaps) with Pduino.
I have looked at the possible components one by one and have arrived at the following which are open to change once I consult with Ed as to their suitability and viability.
This list may work as an indication of what I plan to use so as to gain, at least, a basic understanding of each component part. The coding is something else that I will have to be learnt over time once I procure the parts.
Raspberry Pi 3: used to command the Arduino controller. The reason for this is to make the system automated only requiring to be switched on without the need of a laptop to initiate the programme.
Arduino Uno: having researched the myriad of Arduino models, this one comes up as the universal board that will do most things. I don’t need particular miniaturisation or a large number of I/O pins.
Active Infra Red Sensor: for a proximity sensor capable of analogue output and differentiating distance. It has to be active with a both a IR transmitter and receiver. This sort is called an active (as opposed to passive) sensor. There are various models with different ranges. Other types of sensor include ultra sound sensors which are only suitable for detecting hard reflective surface. People do not make good reflectors as they absorb sound, particularly when clothed. On the other hand, people emit plenty of IR radiation. Sharp appear to offer the best range of sensors at a low price.
Digital potentiometer: to translate the distances picked up by the sensor and translating them into variable voltage that can be used to regulate output.
Media player: which stores and plays the sound files to be controlled. I do not yet know which type, whether incorporated in the Arduino, stand alone, usb stick or using the Pi as a media player. I suspect that using the Pi as a media player might complicate matters and a stand alone player might be simpler to incorporate in physical wiring. This I need to find out.
Breadboard and connectors: There are many sizes and types of breadboard which facilitate wiring without the need to solder. With this I will need jump lead connectors.
Resistors and capacitors: needed to regulate current in the circuit and perhaps a capacitor to help even out fluctuations in current. This may not be necessary when employing an amplifier. I shall find out in due time.
LED: to test the circuit and proof of concept
Amplifier: is needed to amplify the sound signal and protect the Arduino circuit board from being ‘fried’ by the current drawn by the speaker(s). The amp takes the signal in the form of a small current and amplifies it sufficiently to ‘drive’ the speaker physically – which works by forcibly vibrating a drum-like membrane via voltage oscillations in a solenoid. I have a number of amplifiers from old HiFi systems. Alternatively I could get a smaller amp board; which one depends on the requirements of the speaker. A small amp size would be preferable for logistic and space reasons.
Multimeter: for measuring current, resistence, capacitance, voltage etc. Necessary to ascertain values and ensure connections are sound. I do not need an expensive model as it will not need much use, certainly not heavy duty and robustness is not an issue in the studio.
Sound files: whether mp3 or wav may not be important since the sound I intend to use would not suffer from being in high fidelity. After all, most output nowadays is in mp3 and the relative loss of detail is hardly noticeable in normal circumstances.
I have been away from my journal for the last ten days, helping Janet to set up her final show at Camberwell as well as others showing with her. But my mind has not been idle and I have been collecting a number of thoughts regarding work during this period. The insight I have gained regarding how the whole thing works in the context of Camberwell has given me an idea for work. Exhibiting in a group show where each offering is in effect a solo show is challenging. This is particularly the case with sound, an integral part of many digitally based works. In many cases earphones are the solution but some consider the ambient phenomenon an essential part of their work, whether conceptually, aesthetically or just to attract attention. Having this in mind, for next year and other similar situations I am considering using particular bands of the frequency range to circumvent the sonic clutter (and traffic noise) of the group environment, without affecting the latter significantly. In order to deliver this final point, I am considering the use of sensors that modulate the viewer-work interaction periodically. For now I wish to keep this idea private since, if it were to become a meme, its singular affect would be lost.
To incorporate into the sculpture or place near it, a subwoofer speaker. Ultra low frequencies at high volume emitted will set the ambience to vibrate. If the speaker is set inside the sculpture, it may set the latter to vibrate. This phenomenological approach could be used for the long suspended piece. Ultra low frequencies ‘appear’ to come from all directions so the placement of the speaker is not critical for its perception. below the sculpture might be a solution if incorporation is not possible. However, incorporation would bring it to life.
Having the high volume, low frequency on all the time would not be acceptable. A solution presents itself with the use of proximity sensors. Using such devices would introduce an element of interactivity whilst reducing the constant sound to only when it is being viewed. The idea is to place the sensors in such a way that when a person approaches the sculpture, the sound intensifies and the closer the person moves towards it, the louder and more intense is the sound.
The placement of the speaker is a sculptural, technical problem. How the sensors work carries with it a number of questions that I need to address as soon as possible:
what type of sensor to use – motion, light, infrared, microwave etc
how many sensors are needed – this question refers to the mode of controlling the sound output
how is/are the sensors to be controlled – is an Arduino set up required in which can I need to research this and the coding
all the questions lead up to whether a sensor can detect distance and this be translated to variable volume of sound output – is this controlled with the controller or the sensor
if variable output is not feasible, can several sensors be used to trigger variable sound
The ideal would be for the sound to increase in volume as a person approaches the sculpture and decrease as they move away.
It has been some time since the Low Residency. Many thanks to Ed Kelly for condensing into a relatively short time frame a great deal of theory and making. I was already very familiar with Audacity but there is always something to learn and I have taken on board a number of ideas. The great usefulness was to clarify and formalise certain practices that I have followed either intuitively or uncritically. The principle one is the idea of cutting or editing at zero. This avoids clicks and pops producing clean edits. The other is more a concept, that of fragmentation or deconstructing sound into atomic elements which can then be used as building blocks. This ties in with the introduction to Musique Concrete in a Skype lecture a few weeks ago.
We spent time harvesting sounds from a variety of objects. I was particularly taken by a small music box mechanism that Ed brought along. He turned the handle in short bursts while I recorded. This broke up what would have been a familiar melody into fragments of sound. It is a fascinating approach to capturing sound, so much so, that I ordered a number of mechanisms over the web with which I have started to experiment.
Ed mentioned Pure Data, a visual programming software which was, however, too much of a learning curve for the workshop. Although I have started using it, it is too early to say if I shall be using it in the final works, much depends on whether I can find work-arounds to my aims rather than spending too much making-time learning how to use it.
After collecting the sounds, each one of us put together a short soundwork (below). I was particularly taken by the reverberation in the stairwells (pictured above) running up the new building at Camberwell.
The rectangular spiral staircase resonated in my mind with the spiral stairs at the Queen’s House we visited in Greenwich.
The focus of the session was on different approaches to sound as a medium. What Ed means by this is the abstract conceptual manner of seeing sound.
He started with Walter Murch’s categorisation of sound, relating it to colour.
I always find it interesting how sound, music and colour are often correlated. Kodaly is another example of this idea as in his pedagogical work. I would leave the colour aspect out of this discussion and concentrate simply on the semiotic aspect which seems what this diagram tries to convey. There are so many ways of classifying sounds. I have to bear in mind that Murch is a film sound editor. However, the point is to think about sound in terms of its affect and the information it encodes: emotive, descriptive, semantic, associative, allusive, illusive and how these modes are conveyed. Fore example, are they conveyed through rhythm or pitch, distinctive or chaotic? There are so many ways of looking at the matter but in the end I feel the important thing is thinking about sound in terms of its affect, the reason for that affect, how the sound is made, and the context in which or for which it is created.
We looked at musique concrete, starting with Pierre Schaeffer and his first work Etude aux Chemins de Fer 1948, who attempted to categorise sound in his Traité des Objects Musicaux. Michel Chion wrote a guide in English where he lists sounds and their qualities as experienced: PDF.
Musique concrete treats sound as abstract objects each with its own qualities. Particularly intriguing was Bernard Parmegiani’s De Natura Sonorum from 1973 composed using the altered sounds of rubber bands using analogue tape, filters, real echo chambers, delays and altering the tape speed.
Diagetic sound is almost the opposite of this. It is associated with a visual cue as though the situation portrayed is the source of the sound. Musique concrete decouples the corporeality of the sound for it to become the corpus of sensation itself. In a conceptual sense, it has no source other than its own sound. The way it is made may be a curiosity or of methodological interest but in its truest essence only a vehicle. It is as an Acousmatic experience in which the cause and origins of the sound are removed so one can concentrate on its sensations and qualities.
Ed introduced the idea of copyright as a ‘spanner in the work’ and then goes on to give some examples of postmodernist sound collages where recording are appropriated to create mixes. Whereas in the case of John Cage’s 1953 mix, in which each situational element is recorded in his own house over a period of time, here we are talking about taking pre-existing recording and butting them either as live performance or recordings. The copyright situation is complex here depending on duration of play, recognisability of the segments taken and in the case of live performance, proof of actual appropriation. Perhaps that is why one of the people doing this uses discs. Ed describes each discrete segment as the ‘cultural grain’ of the whole rather than musique concrete’s sonic texture. It is interesting to look at it in those terms.
All the content is from a single take performance with light in the studio involving a Graven Image. The sound I generated in a variety of ways and the music is my remastering of a 89 year old 78 rpm recording.
