Tim: Could you please explain, for those who don't know, what a Soundbeam is?

David: A Soundbeam is an invisible elastic keyboard, in the air, but it's a keyboard that you can adjust; it doesn't have all the notes all the time and it isn't necessarily one sound all the time, or necessarily one size - so it can have one note and be tiny or it can have 64 notes and be 6 metres long! - or 64 notes and be 43 centimetres long - you know it can have anything you want in it but the important thing is that you have to move within it and the better your quality of movement within it the more beautiful the music's going to be because that's always been the case with music.

David: You have to programme what notes are in the beam, programme the articulation and the articulation is a very very powerful part of Soundbeam because it allows you to play up and down the beam, in and out of the beam, start and and stop sounds in the beam, lots of very sophisticated playing techniques for the beam which really have to be taught - but, having said that, certain disabled people play it with an intuitive understanding which defies belief - they seem to know how it works, which is marvellous.

David: Well, I would insist that I am not a music therapist - There may be therapeutic benefits from what I do, but they are much the same as I get a lot of benefit from being able to play my saxophone in practice - it's an occupational therapy for me to practice and write my music and it might be physiotherapy for a disabled person with cerebral palsy to play a Soundbeam and struggle against their own out-of-control nervous system - it might be exercise, and physiotherapy - so there are many therapeutic benefits from it, but I AM NOT A MUSIC THERAPIST, because a music therapist is a therapist using music as a tool for therapy just as a psychotherapist would use their training in psychology and psychoanalysis to use for therapy just as a music therapist uses music as a tool - but they're primarily therapists and they're not interested at all in performance - I am totally and utterly committed to performance and thereby totally and utterly disqualified from doing any therapeutic work. It's a very very specialist area and it holds no great interest for me.

David: 14 Attainment Targets! Ha Ha for an 11 year-old. The fact that an 11 year-old in 1988 had to do 14 attainment targets when the rest of us were trying to get them to add and subtract - you know, that was two attainment targets - what were the other 12 - there were algebra, geometry, I mean they were just barking!
