A few years ago while performing in Nashville, Tennessee I attended the annual conference of the National Association of Music Therapists. While much of what I saw was very encouraging I left with mixed feelings. It was obvious there was a great enthusiasm for exchanging information on therapy but there was very little understanding of the music aspect of Music Therapy. It seemed to me that by general unspoken consensus any sound produced by a musical instrument was by definition music. The sound produced by a violin or a drum is no more musical than the sound produced by hitting a car with a hammer. The violin has arguably a greater potential for creating music than a car but only in the hands of a musician who is using the violin to communicate. The art form of music is a language of communication, sound is only relevant in that it is the medium through which music travels. Although I am not very experienced with Music Therapy, virtually everything I have seen leads me to believe that what is actually happening is Sound Therapy and that Music Therapy is a misnomer. In one instance I played for a boy who was deaf, blind, brain damaged and had to be constantly restrained as he was unable to control the erratic behaviour of his muscles. The boy was held on the wooden floor underneath my marimba so that he might feel the vibrations. Within a few minutes of my starting to play a piece of music depicting a gentle sadness the carers were able to release their grip and the boy's muscles relaxed. I then played a fun and cheeky piece of music and the boy waved his arms in a controlled manner and smiled. The boy had been in care all his life and between tears his carer told me that to their knowledge, in his nine year old life, this was the first time the boy had been seen to smile, had shown any muscle control or indeed had responded in any way. As a language of communication I believe that music has huge potential in the area of therapy.
