Alexander himself was an actor and developed the technique in response to recurring voice loss during his performances. Onstage, we experience hightened levels of stress which can accentuate habits that otherwise go unnoticed. Holding our breath, tightening the stomach, neck, leg or shoulder muscles interfere with the fulfillment of one's potential, and can lead to pain and injuries. Through the Alexander Technique, performers learn how to use mobility rather then rigidity as a centering focus. They are able to identify harmful habits and abandon them, grounding themselves in the present reality. Maintaining the body open and poised allows better resonance, making the artistic intentions clearer.

Some of the renowned actors and musicians who have been using the Alexander Technique since the beginning of this century are: Trisha Brown, Julie Andrews, William Hurt, Jeremy Irons, James Earl Jones, Paul McCartney, Kelley McGillis, Patti Lupone, Paul Newman, Sting, Maggie Smith, Mary Steenbergen, Robin Williams, Joanne Woodward, and members of the New York Philharmonic.
