Echo + Seashell consists of artists Henna Hyvärinen and Susan Kooi Together they write and perform songs about their problematic art- and love life, based upon what is going on at the moment. The music is produced by and in collaboration with different musicians, resulting in variations in both style and genre.

The lyrics form the core, the “baby soul” of Echo + Seashell. Their collaboration consists out of live performances, videos and exhibitions. After having received many rejections on both a personal and a professional level, they recently produced a musical on the theme of rejection. For this project they held an open call, inviting people to send in an instrumental song. Striving for 0% rejection, they used all the 18 songs that were sent. For some they wrote lyrics, for others they made videos or found another platform. The musical consists of four parts: In the Game but Losing It, Hard and Soft, Project Runaway and Coldplay.

Since I began working on my project The Neighbours (2006) every sound started to have an impact. At first I couldn’t work properly as I was constantly irritated by the sound of the upstairs neighbours. I was cross with myself that something so trifling could loom so large in my head. I lay on the bed. I tried for a while not to hear anything; it forced itself on the periphery of my consciousness, like a hum, like a dripping tap. I was quite astonished when I realised that this could lead to my making a work. Precisely because it is so trifling. Precisely because it is on the edge of my conscious perception.

The more I became preoccupied with my neighbours, the more sounds I’ve begun to notice. My ears have become more sensitive to detail since listening to my neighbours even for the subtlest of sounds. When visiting someone, I hear more. It is amazing how often you hear someone coughing in the house next door.

This applies even more to hearing the neighbours above me. In the six months they’ve lived here, my home has changed. They have taken over my space. I went mad with irritation lying awake on my bed and so I decided to reverse the roles by taking the noise they made as a starting point for this project . Ironically, I now miss them if I don’t hear them for a minute and I am glad of any strange new sound they start to make. Listening to them gives me a feeling of being busy with something (acute and exciting). I was devastated when they insulated their floor with new underlay flooring. I think it is new but I can’t be sure as I only hear their sounds and I have never met them.

Imperceptibly, the process of being aware of the upstairs neighbours in my daily routines reached the point where one Friday night I realised I was waiting for their shoes to fall next to the bed. I knew how this would sound. I knew that this would be followed by the dreary hum of the satellite dish above my window. I was, I realised, constantly preoccupied with them: people I once briefly spoke to over the phone but with whom I never actually met. I know their bedroom habits down to the most intimate (acoustic) details.

I try to imagine them, but the image remains vague. I imagine them as people who often go to the local gym (on the corner), with something inflated about them, as if they’ve been carefully pumped up to a critical point. But what am I actually basing this on? Also, it isn’t their physical appearance that keeps me awake. It is the space they take up in my home with their sound, since this makes me always aware of them.

Because I hear my neighbours, they’ve actually infiltrated my space: not with their bodies but with their sound. They disturb what my home is for me – a place where I can do what I want and others can’t.

The silence of my home is my home. My private space. But what is this silence in fact? It is not what I would term real silence. There are the birds, my fridge hums, and cars drive past. However, that is the background noise to my home, I am used to it.

There is a prodigious link between sound, space and awareness.

The notion of background sound, already has something spatial about it like a kind of environment, a private room you can always – when it is quiet – take with you. Certain people might feel exactly like this about a lot of sound, which is then their ‘background’ and perhaps they feel uneasy when it is missing. Unexpected noise is saying that this private space doesn’t exist, especially noise from which you can’t escape and about which you can’t do anything. A dripping tap is less frustrating as I know I can also switch it off, but the neighbour’s noise is uncontrollable. The only thing I can do is adjust to it, or phone them up and hear my phone upstairs, or have the music very loud, which gives a kind of temporary satisfaction.

If my upstairs neighbours are unexpectedly quiet, something strange happens. The quietness drives me mad. It is like a story I read about a man who every night was resigned to hearing his upstairs neighbour throwing off his shoes one by one. One night, the upstairs neighbour, in a sudden fit of awareness after having taken off one shoe, thinks the sound is antisocial. He is overcome with guilt. With the precision of a moon landing, he then places the right-hand shoe next to the other. After fifteen minutes he wakes up with a start. He hears a voice crying: ‘For goodness sake, take the other shoe off, then I can get some sleep!’ I am now so used to my neighbours’ routine sounds that they’ve become almost my background noise and indeed I now notice when they’re missing.

Sound and harmony made visible. Lissajous patterns made with 2 audio oscillators, a loud amplifier, plastic wrap, a bowl, and a laser pointer.

Easily mistaken for the infinity sign, a circle or any number of more complex pretzels and knots, the Lissajous Figure is a picture of compound harmonic motion named for French physicist and mathematician Jules Antoine Lissajous (1822-1880). The shape is drawn by plotting a two-variable parametric equation as it iterates itself over time – the resulting figure is the picture of two systems falling into and out of phase.

In 1855 Lissajous constructed his "beautiful machine," devised to draw a picture of two systems superimposed and constructed in his Paris workshop of a pair of tuning forks placed facing at right angles, each with a mirror attached. The light source is focused through a lens, bouncing off the first onto the second and projecting to a large screen a few feet away. As the tuning forks are struck and tones are produced, simple vibrations begin to move the mirrors in a regular oscillating pattern. The projected image begins to form the strange and beautiful curves of a Lissajous Figure.

For his machine Lissajous was awarded the Lacaze Prize in 1873 and was exhibited at the Paris Universal Exhibition in1867. He did not otherwise distinguish himself as a scientist or mathematician. In fact, almost fifty years earlier American Nathaniel Bowditch had already produced similar figures with his harmonograph.

The simple harmonic motion which Lissajous was measuring is easily described by the motion of a clock's swinging pendulum. As the pendulum swings its speed isn't constant, but rather it accelerates and decelerates following a precisely predictable curve. If plotted over time, as the clock ticks the motion of its pendulum draws a sine wave – the so-called "pure wave" or zero-picture of a simple moving system. Ocean waves, sound waves, light waves, even average daily temperatures all produce this same oscillating sine wave pattern.

Compound harmonic motion, then, is simply the superimposition of two sine waves as they register, interfere and produce a series of overlapping waves. When juxtaposed at right angles, two sine waves recording simple harmonic motion produce the surprisingly complex figures that Lissajous identified.

Sound Pattern 03

Sound and harmony made visible. Lissajous patterns made with 2 audio oscillators, a loud amplifier, plastic wrap, a bowl, and a laser pointer.

Lissajous Figures can be easily found today in computer graphics, in science museums, in laser light shows and, perhaps most precisely, burned into the green phosphor screen of a cathode-ray oscilloscope. A standard piece of electronic test equipment, the oscilloscope allows signal voltages to be viewed as a two-dimensional graph of potential differences, plotted as a function of time. When testing an electronic system, the phase differences between two signals form opposing sine waves on the screen of the oscilloscope connected together, constantly drawing and redrawing themselves in a precise and regular pattern.

These two varying signals produce a perpetual infinity (figuratively and literally as it will actually construct itself in the shape of the infinity sign given the right initial values). The Lissajous Figure becomes a picture of timing and sequence, registration and resonance, sound and music.

Specific shapes are produced corresponding to the resonating harmonic intervals familiar from western music (major fifth, minor third, major sixth, etc.) Any figure may be transformed into any figure and an infinite number of in-betweens as the oscillating sine waves pass in and out of harmonic resonance.

Jules Antoine Lissajous created a way to see sound (using mirrors, light and vibrating tuning forks.) But the most radical possibility of his mathematics might be in the commitment it asks of its audience. The image that Lissajous produces forms slowly right in front of your eyes — imperceptibly changing, forming, adjusting and re-aligning over time.
