As Alexander himself was an actor and interested in performance and the use of the voice, his work has long been recognised in the world of acting, singing, music and the performing arts. Many of the major drama and music colleges in the west include Alexander lessons scheduled into their programme. Through the teacher's guidance, the pupil is able to experience a different co-ordination of their body which allows them to function with less strain and greater freedom. With singing or public speaking for instance, when the relationship of head, neck and back is working well, the voice and breathing mechanisms can function at a much higher standard - leading to greater expressiveness, and less risk of strain or injury. In the same way, when musicians are able to handle their instruments with less inappropriate tension, it is natural that there will be more space for creativity and expression in playing music.
