Music is a great tool for expression. The music artist takes you on a journey,a rollercoaster ride of feelings and emotion. Descartes said 'Cogito Ergo Sum' - 'I think, therefore I am'. The musician thinks and then performs and his work, that all can hear, his art, becomes one with the audience. a Transferrance of energy occurs and the form of the art manifests itself in the feelings of those that listen.
