ABSTRACT

Recent advances in movement sensor and other technology have utilised various electronic media to create human - machine interfaces with apparently significant but largely unexplored educational potential. Such systems have often been conceived and developed for purposes outside the sphere of formal school education or therapy (e.g. performance art, dance, electroacoustic composition, VR environments, video animation), yet preliminary research demonstrates that it is the school environment in which such technology can contribute most dramatically; specifically to the educational experience of young children with severe disabilities who may have missed the foundation stones of early learning and for whom a first experience of enjoyable control and initiation can be a crucial educational motivator.

‘Aesthetic resonation’ is a term coined by Dr Phil Ellis to describe special moments experienced by individuals described as having profound and multiple learning difficulties, in which they achieve total control and expression in sound after a period of intense exploration, discovery and creation. Enjoyment and self-motivation are key aspects of this work, which Ellis describes as Sound Therapy.

Soundbeam" is one example of such technology. It emits an ultrasonic beam of variable range. Movements within the beam generate data interpreted by any MIDI instrument. Essentially, its an invisible, elastic keyboard in space that allows sound to be created without the need for physical contact with any equipment. Originally developed for dancers - giving them a redefined relationship with music - Soundbeam has proved to have dramatic significance in the disability field, because even with profound levels of impairment the most minimal movements can instigate and shape interesting sound effects, trigger rich and exotic aural textures, or perform soaring improvisations. Individuals especially difficult to stimulate can benefit from what may for them be a first experience of initiation and control. The core objectives of this presentation are:

INTRODUCTION

The focus of this presentation is a specific item of technology - Soundbeam - which (at least in theory) makes the universal medium of music newly accessible, particularly to those who, because of disability, might hitherto have been denied independent creative experience.

The idea of a musical instrument which could be played without any physical contact was first developed by Leon Theremin, the Russian composer whose 'Thereminvox' astounded audiences in the 1920's, and which can be heard on the soundtracks of countless low-budget sci-fi movies. Most people have never heard of the Thereminvox, but nearly everyone has heard one played. In spite of its 'scary monster' associations, the Thereminvox (which is currently enjoying something of a comeback) is intended as a serious musical instrument. Repertoire exists for it, and the performances of Theremin virtuoso Clara Rockwell attest to the instrument's expressive power.

Soundbeam's development was inspired by the Thereminvox. There are, however, two essential differences between the two machines. Firstly, whereas the Theremin creates a fixed playing zone close to the device itself, Soundbeam (designed for dancers) incorporates a variable ranging control which allows the invisible beam to be compressed into a few centimetres or stretched out to cover an entire stage area. In practice this means that the invisible instrument can be varied in size to accommodate the movements that the player wishes to perform, or is capable of performing. The second key difference is that whereas with the Theremin variations of timbre were not available (you were more or less stuck with the scary monster sound), Soundbeam - on its own - produces no sound at all. Instead, the machine functions as an information processor which translates distance and movement data into signals which are understood by electronic instruments, so that any sound which a given instrument will generate can be 'played' with the beam.

Soundbeam works by emitting an invisible beam of high frequency sound (ultrasound) inaudible to human ears. The ultrasonic pulses are reflected back into the device's sensor by interruptions of and movements within the beam. Information about the speed and direction of this movement is translated into a digital code (MIDI) which is understood by a growing proliferation of electronic musical instruments, from relatively simple and inexpensive home keyboards to professional studio-quality synthesisers, samplers and expanders.

The system incorporates three principal control parameters. Variations in Range settings allow the length of the beam to be varied between 0.25 and 6 metres. Shorter beams concentrate note information into a relatively small space, a set-up which has proved to be of significant value in special education where player's ability to move expansively may be limited by disability. Longer beams allow a complete performance space to be 'live' with sounds. Transpose settings allow semitonal modulation of the scales contained within the beam, useful where the beam is played alongside other electronic or acoustic instruments. Mode settings govern the realisation of note information contained in the beam. Each of the Mode presets comprises four variables: the number of notes potentiated (between one and sixty-four), the relationship of those notes to one another (scales, chords and arpeggios), the articulation required to activate the note (the dynamics of the movement in relation to the sensor), and secondary information such as velocity, pitchbend and modulation depth. In addition to the resident Soundbeam 'memories' it is also possible to load a user-defined sequence of notes into the beam. This has the benefit of enabling a considerable degree of compositional exploration without the necessity for a commensurate level of keyboard skill: an idea can be programmed in at the user's pace and then performed in real time with dance or simple movement. Up to four sensors can be attached to the basic system. Thus it is possible to have a three-dimensional playing space, with beams each of different length, each angled in a different plane, and each with its own sound or 'voice'.

SOUND THERAPY

In traditional music therapy, the less the child is able to say something with sound because of a physical or cognitive disability, the heavier becomes the therapist's responsibility for empathy and interpretation . The main focus and engine for the mood and meaning of the music which is happening is on the therapist, and this creative and interpretative role is increasingly shifted away from the child with more profound levels of disability. Consequently, as the liberating potential of musical expression increases, it becomes correspondingly less achievable. This allocation of creative 'power' may have no clinical or therapeutic rationale, it may simply result from what is physically possible. New evidence suggests that Soundbeam can provide answers to this problem.

The experience of initiation is central to the success of Soundbeam, especially for individuals with profound disabilities. If ones overall experience of life is essentially passive, it may be difficult to develop any concept of 'selfhood', any idea of oneself as a separate individual. What Soundbeam offers, perhaps for the first time and regardless of the individual's degree of immobility, is the power to make something happen. This is the vital experience of "that was me!", which can function as the foundation stone for further learning and interaction. This use of sound as the source of motivation is an extremely simple but crucially important application of the technology; it is impossible to overstate its value.

Work by Dr.Phil Ellis (Ellis ‘94, ‘95, ‘96) at the Institute of Education at the University of Warwick in England has provided us with the first systematic long-term evaluation of Soundbeam's potential for children and adults with disabilities. The beam is positioned so that as soon as the child begins to move an interesting sound is triggered, motivating further movement and, eventually, radically enhanced posture, balance and trunk control. All of this is accomplished in parallel with a strong sense of fun and achievement. For the child, the therapeutic dimension of what is happening is irrelevant. Ellis also discusses some of the broader aesthetic issues connected with his approach:

“There are differences between sound and music, but the term ‘music’ may now encompass a broader sound spectrum due to the possibilities which have emerged during this century through the increasing use of electricity in music. As early as 1932 Stokowski predicted a time when musicians would be able to compose directly into TONE, not on paper. In other words we would be working directly with sound itself rather than with the symbols used to represent the results of imagined combinations of sound. Furthermore, through sound synthesis electricity has made it possible to discover and create sounds which have never before been heard, and which could not be created any other way. In addition, we can simulate... a range of acoustic environments - concert halls, rooms, cathedrals or other large spaces for example, or may create acoustic environments which are impossible to encounter in the external physical world. This aural richness and variety provides the internal motivation which lies at the heart of this approach. In addition the technology also provides physical access for the disabled.

....Sound itself is the medium of interchange... This approach contrasts with traditional models of music therapy, with its emphasis on ‘treatment’, direct intervention and imposition of external stimuli determined by an outside agent. Even where a music therapist may claim to be ‘responding’ to a patient’s music, this is a personal response on the part of the therapist. Often the therapist uses, or moves towards, a traditionally based musical language comprised of melody, harmony and rhythm, so limiting the soundscape and genre of ‘musical’ discourse. The ‘patient’ or ‘client’ is viewed in a clinical way, with a condition which needs to be treated or ameliorated. There are clearly defined goals with these treatments, with success measured according to how effective the treatment has been in terms of the clinical or medical condition. The modus operandi of these approaches is essentially from the outside -in, with an emphasis on clinical intervention rather than independent learning.

In Sound Therapy a different, contrasting approach is taken. Whilst progression and development remain a key focus, the essence lies in the internal motivation of the child, in working from the inside - out. This internal motivation is produced through the use of sound within a carefully controlled environment. At all times the child is given the opportunity to independently take control of the situation as far as possible. Certain aspects are controlled externally - notably the sonic environment - but the essence lies in allowing the child freedom to act as she or he chooses within available parameters which remain as open as possible. In this way, learning occurs incidentally. As a result we can see progression and development in a variety of ways across a range of disabilities. Such progression is not prescribed in advance, but happens as a natural and additional part of activity, all stemming from the internal motivation of the child - a phenomenon referred to as aesthetic resonation. This is made possible through a particular use of sound as the primary medium of interaction, and through giving access through the use of technology, so enabling even profoundly handicapped children the opportunity for expression and control - in other words the encounter with and development of communication skills - through sound.”

From systematic analysis of videotape session records, Dr. Ellis has identified nine criteria of progression and development:

  1. from involuntary to voluntary
  2. from accidental to intended
  3. from indifference to interest
  4. from confined to expressive
  5. from random to purposeful
  6. from gross to fine
  7. from exploratory to preconceived
  8. from isolated to integrated
  9. from solitary to individual

He notes that even profoundly disabled children respond to Sound Therapy by:

"...in addition, a change has been seen in behaviour patterns beyond the immediate environment of Sound Therapy. Some children are now more self-aware and are interacting...Other children show more tolerance and a growing awareness of other people, moving towards interpersonal skills."

In these early explorations of the beam the therapist has two important jobs. Firstly, to select from the (probably hundreds) of available sounds, interesting and motivating ones which will stimulate interest (this is particularly important where cheaper synthesisers are used as these will contain many uninteresting and unpleasant sounds), and to sustain engagement by changing synthesiser voices and, possibly, Soundbeam modes so that musical output does not become tedious; and secondly, to observe and estimate the various axes and degrees of physical movement so that the 'invisible sounds' are optimally positioned in relation to the child's body.

“.... few of these children have the necessary physical co-ordination or control necessary for traditional musical performance. However, we can legitimately shift the view away from purely traditional musical qualities towards the new and developing musical aesthetic, one which has in part been enabled through the introduction of electricity to musical activity. In so doing many musical doors can be opened and we can all enjoy being expressive with sound... Many of these techniques can be made easily accessible to virtually all children through technology.”

Kathryn Russell (Russell ‘96), working in Australia has also identified a number of areas of development with the special students she involves with Soundbeam, including:

“Bearing in mind the extremely short attention span of many children with special needs, students have demonstrated a remarkable capacity to focus on their improvisations for long periods of time, thought previously to be beyond their abilities.....Those using Soundbeam for music education have discovered that children who are able to take control of their music making develop not only expressive and practical movement capabilities, but also create improvisatory music which has relevance and validity”

FROM THERAPY TO PERFORMANCE

Russel’s findings, like those of Dr. Ellis, provide a systematic assessment of physical and affective responses, giving quantifiable data about Soundbeam's clinical possibilities. In parallel with this approach, many projects in the disability field are exploring the creative performance-based paths opened up by this new technology. At 'The Ark' in Bracknell, a multi-arts project for people with learning difficulties, dancer Penny Sanderson and musician David Jackson's workshops always involve a narrative theme, and include live music, dance and drama, providing an excellent example of the way in which technology can be used to complement and enhance a successful established activity (rather than a sterile 'technology-led' approach) in a way which allows participants a fuller involvement. The sounds and tunes triggered by the students' movements in the beam have a place in the story and are tailored to the personalities and moods of the individual students. Dinosaurs, waterfalls, butterflies, monsters, princesses, lions, explosions - this aural dimension is all controlled and modulated by the students’, and this in turn reinforces and remotivates their involvement.

Fransisco Borges da Souza, a music therapist working in Portugal, has formed a rock band with Soundbeam as one of the key instruments. The astounding expressiveness of the disabled Soundbeam player clearly reveals a talent that has been unlocked.

Special schools in England are now starting to collaborate with so-called ‘mainstream’ schools on music projects involving Soundbeam. As the children are able to learn and perform on an equal basis, the disabled/non-disabled barriers can be broken down. English special schools are often isolated and the arts can clearly give a strong focus for integration where this can be enabled by appropriate technology. Meldreth Manor School in Hertfordshire and the Ormerod School in Oxford are outstanding examples.

THE SOUNDBEAM PROJECT

We are taught that 'serious' musicianship demands years of dedication. So what are we to make of devices which allow musical expression to happen almost immediately? How can we asses the musical validity of what we hear? With conventional instruments, designed for those with average or above-average physical, mental and sensory functioning, the time gap between musical imagination and musical realisation takes years to develop. Good technology radically shortens this gap. It extends the limits of selected-scale or percussion based work, and it asks the player to learn not the technical skills of the traditional instrumentalist but the freedoms and disciplines of improvisation. This kind of music is difficult to evaluate because there are no right or wrong ways of playing it - no performance of a piece of music played with Soundbeam will ever sound the same twice; but it is possible to assess the extent to which the student enjoys it and gets a feeling of achievement from it, and some of the preliminary research reviewed here indicates strongly that the attainment of significant milestones in the physical, cognitive and social development of individuals with a range of disabilities can be radically assisted by the use of such technology.
