The Xerox machine or photocopier,  is one of my most favoured drawing instruments. If time, and credit permit, I take full advantage of its ability to, replicate, generate and damage visual information. The dry (xeros) writing (graphia) process of electrophotography is of course intended to reproduce: to copy and duplicate quickly. However, the copying process introduces its own artifacts, through the mechanical and chemical degeneration of information, scratches and dirt on the glass plate, and banding streaks of diminishing ink. Such inherent loss has the potential to transform a copy into an original copy, which is both unique and singular. The forensic study of such blemishes of reproduction can actually be used to identify specific brands and models of photocopier. Such unintentional errors constitute a form of steganography or concealed writing, inscribing a hidden message, available only to those who know it is there: visual notes that only some can read

It would perhaps then seem appropriate to use Xerography as a method of creating or rather, [re] producing a graphic score. The reproduction process feels distinctly hand rendered: the touched weight and texture of each sheet of paper, the gestures of hands choreographed by the feeding and retrieving procedure. Although immediate, there is a hesitant, analogue delay, as the photo-chemically scored ‘copy’ arrives concealed, face down and late. The optional manual feed allows for the use of different (‘thick’) papers and the reorientation, repetition and layering of inscription. For me the actual labour of making the copies regenerates memories of etching and the traditional printing process.

The xerographic scores are not made in response to sounds, like some of my other graphic scores (for example, the (mono)printed, ‘drawn’ & copied score for Yvon Bonenfant’s Masz project (see below) made in response to Diamanda Galas’s Plague Mass, or the traced, Letraset score for three landscapes and a river, made in response to my own soundscapes). The copier scores are intended as a method of making sounds yet unheard, available to hearing. They offer poetic, visual organisations of sound, open to the error of reproduction and indeterminate of any prescribed sonic response.

‘My favorite music is the music I haven’t yet heard. I don’t hear the music I write, I write in order to hear the music I haven’t yet heard’ (John Cage).

Theresa Sauer’s excellent book Notations 21, explores the graphic scores of composers such as Cage, Earl Brown and R. Murray Schafer, allowing an insight into the compositional strategies of the musically adept. As a non-musician, who cannot read musical notation, the graphic score allows for a dialogue with sound in which visual and aural information enter into correspondence. The dry writings of the Xerographic scores, offer an opportunity for not only the interpretation and organisation of yet sounds yet unheard, but also an appeal to the ‘unstruck sounds’ (Schafer) available to the imagination. Might they also allow the eye to adopt the perceptual inclination of the ear? The eye, so concerned with isolating information and bringing the indistinct into solid focus, may become draw into the unlimited rhythms of attention and hesitation, more normally allied with listening: allowing the visual to take on the perceptual ‘condition of music’ (Walter Pater).

Last week I had a wonderful day with Simon Park, recording the sounds of the microbiological laboratory at Surrey University. Simon, an expert in microbiological luminescence, had very kindly set up a number of cultures: a conical jar of yeast and two petri dishes of other luminescent microbe colonies. The cultures are kept in a series of incubator rooms set to different temperatures in order to aid the growth of microbes. The room set to human body temperature is breathtakingly warm; I had no idea that I was this hot.

This initial visit to the lab was a kind of acoustic reconnaissance: lets listen to what is there to hear. Simon showed me the various machines used to stir and agitate the liquid cultures. This includes the ‘Magnetic Flea’, a seemingly uninteresting, elongated plastic covered magnet, visually not unlike a suppository. However, when the flea is put into a jar placed on a spinning machine, it begins an untidy clangorous choreography, as it rattles against the glass walls of its container. Finding equilibrium, it produces a distinct pattern of movement and sound, each magnet composing its own percussive stir: unique to that jar, that flea, in that moment and that position. The patterns continually evolve and change like listening to waves fall onto the shore, a sonic equivalent to the visual patterns of growth produced by the microbes in the petri dish.

We spent hours (and I do mean hours) trying different jars, different fleas, different microphones, and different spinners. Some of the machines allow the speed of stir to be varied, so that the jars can be ‘played’ like a musical instrument. And whilst some machines spin to stir, others have a gentler shaking action, like the clichéd motion supposedly used to swill brandy around the bottom of a glass.  I recorded many variations of instruments, jars and microphones to capture a canon of growing percussive patterns.



In one of the incubator rooms I placed contact microphones against the sides of a conical jar containing yeast. On the surface of the solution you could see small eruptions of gas as the yeast feeds, digests and expels. In appearance it is not unlike looking through a telescope at the surface of some gaseous planet. It is interesting that visually we often find the microscopic and macroscopic interchangeable: so what would be the audio equivalent? I suppose the contact microphone may be seen as a form of aural microscope: delving beneath the surface to listen to the very substance of things, bringing the tiniest sound closer and making it available to the ear.

Through the glass membrane of the conical jar, the snap, crackle and pop of yeast digestion is audible, although the contact microphone also picks up the vibration of the incubators heating system  travelling through the metal shelving system. This metallic hum adds a laboratorial ambience to the sound here, (I have reduced it slightly in post-production, so as to emphasise the sound of yeast). The drone of environmental climate control could perhaps be called the ‘keytone’ sound of the laboratory (and of the archive; a soundscape I have also explored). R Murray Schafer described a Keynote sound as ‘often not consciously perceived’ but ‘heard continuously or frequently enough to form a background against which other sounds are perceived.’ In the laboratory the hum of temperature control pronounces an acoustic stasis, the pulsing sound of time standing still.

A hydrophone sunk into the solution, is surrounded by the digestion of yeast, although again the ambient sound of the laboratory is also present in the mix: this time it’s the voices of people preparing to experiment. In order to get a larger hydrophone in on the action, we decant the yeast to a metal pan and notice (through the microscope of contact microphones) a change in the acoustics resulting from the metal skin of the pan. Another experiment, set-up quickly by Simon, involved two conical jars and a rubber tube. By gently stirring one jar full of yeast, the gas escapes up the tube into a jar full of water, producing quite delicious bubbles of effluent.

The yeast songs have their own pattern, as the microbes consume all available oxygen and food, the static crackle of their existence is extinguished. There is the possibility of producing a spatial and acoustic bell curve, through which could be heard the life cycle of these microbes, their multiplication, peak and extinction: a microbiological soundscape, beginning with silence and returning to it.

Plan of predicted route through theatre


On the 31st October, artists, musicians, dancers, writers and other creatively inclined individuals and groups from the Winchester district occupied the stage and architecture of the Royal Theatre, Winchester. Unlike the worldwide occupy movement, this occupation was curated by Trisha Bould at the invitation of the theatre and was part of an opening event for the Ten Days Across the City, arts festival. Beginning at six and ending at the stroke of midnight, Map, Plot, Plunder and Possession led its audience behind the scenes of the theatre, into the normally concealed backstage areas of the building.
As part of the event, I composed a cycle of three soundscapes for the auditorium and a sonic river for the public address system. The cycle included soundscapes from the winnall moors sound walk project and Winchester Cathedral, that had been specifically re-composed for the site of the auditorium. In between the two soundscapes, I inserted a percussive interval created by evoking sounds from the lighting and scenery rig of the stage; swinging the descended rigging and occasionally hitting it with a toy xylophone mallet.
The soundscapes were intended to inhabit the acoustics of the theatre and act as a consistent cycle of sound spaces that would come into contact with other acoustic events taking place during the evening. This included; a rehearsal of a song by the Winchester Community Choir from the theatre circle; and the indeterminate composition Copy Rite by Hossein Hadisi and other members of ACE (Avant-garde Composer’s Ensemble).
The choir began their rehearsal in the percussive Interval, before being acoustically repositioned into the soundscape of Winchester Cathedral, the opening of the Cathedral gates, the organist at practice. Perhaps most pleasurable was the choreographed pile up of rehearsal as the community choir’s preparations collided with the Pilgrim school rehearsing in the Cathedral.
In Copy Rite, Hossein Hadisi and the other members of ACE (Sam Cave/Guitar; Tom Green/Piano & Ignacio Agrimbau/Gyil & Hulusi) moved around the theatre between pre-arranged sites within and without the auditorium: a piano in a stairwell, a guitar on the first floor of the atrium. The sounds of the auditorium were fed back into these satellite positions, all the musicians responding to the sounds, acoustics and other visual events occurring around them. Both the choir and Copy-Rite, created some rather unrehearsed collisions with the continuous cycle of soundscapes.





The peripatetic music of ACE, mingled not only with its disparate musical parts, but also the acoustics of the theatre and the patterns and dynamics of the entire recorded and existing soundscape. The sonic river, composed entirely from the sounds of water from winnall moors, leaked, flowed and dripped into the acoustics of the architecture. In the front of house speakers the water generated small wet, but distinct pockets of sound. In the non-space of the corridors the speakers created a ventriloquial soundscape, the echoic drips evading location. In the atrium, the dripping of water echoed the pluck of guitar strings, the river seeming to rain down from the heavens, although the speakers were actually located. A fragment from this unpredicted duet appears on the winnall moors sound walk blog, along with a section of the unaccompanied sonic river.

graphic score: three landscapes and a river 6Yesterday I tested three soundscapes for an event at the Theatre Royal Winchester. The event called Map Plot Plunder Possession will form the centerpiece for the 10 Days Across the City art festival.

My three soundscapes are extended versions from the winnall moors sound walk project; Winchester Cathedral; and an abstract ‘interval’ composed from sounds evoked by ‘playing’ the hanging rods of the lighting/screen system. The interval maintains the sequence and rhythm of the original ‘live’ recording, but the sounds have been layered and manipulated slightly, to create three variations on a theme, each interval separating the moors and Cathedral soundscapes. I also composed a sonic river, which will be running through the theatre public address system. The public address system provides a strange form of acousmatics, locating the sound whilst simultaneously suggesting a space beyond the visible.  The system disperses the origin of the sound and creates different architectural pools and tributaries as the sound interacts with the acoustics of the space. The towering atrium space creates an immense reverberation chamber, which again hides the source of the sound, whilst in spite of the speakers actually being located at head height, suggests a waterfall of invisible rain pouring down upon our ears.
As with many of my other sound works I am interested in the problem of drawing from the sounds visually, in the form of a graphic score. As with my score for Yvon Bonenfant, the drawings are not intended to represent the sound as much as conjure up a method of translating sound into visual form, which allow others to reinterpret back into sound. Not being a musician and working with field-recording & phonography, I am using sounds that are not normally notated. However, I am interested in the synaesthetic dialogue between visual and aural material and the handing over of compositional control.
The graphic score for three soundscapes and a river, uses old Letraset and the process of tracing and following the mapped lines of rivers, which run through the moors and around the Cathedral.  The compositional drawing unintentionally mimics the digital waveform pattern of the sounds.
If any musicians would be interested in interpreting these graphic scores, please get in touch.

I’m currently working on soundscapes for the opening event of 10 Days Across the City festival, at the Royal Theatre, Winchester. I had a tour of backstage and even better, understage: this is the view from the orchestra pit. Spatz (the theatre’s chief technician) lowered all the stays that normally suspend lights and scenery over the stage and I attached contact microphones and ‘played’ them by rattling them and setting up gentle swinging patterns.  I used the sounds captured to create a short metallic interval that will interrupt the two soundscapes broadcast into the auditorium on the evening of Halloween.
