The Alexander Technique
was developed at the end of the 19th century by a young Australian
actor named Frederick Matthias Alexander. His original goal was simply
to improve the stamina of his own voice - he would suffer from
increasing hoarseness each time that he performed.
unable to offer any help, Alexander spent time studying himself to
determine if he could affect the situation. He became aware that he was
holding excess tension in his body and that by changing the way in which
he moved and carried himself the tension was alleviated.
As well as
solving the issue he had with his voice, Alexander's overall health
improved so greatly that people he knew, and doctors that had been
unable to help him, convinced him to teach others what he had learnt.
