An actor needs to be present and spontaneous to be most effective on stage or screen. An actor wants to be able to express a full range of body movements and emotional expressions from larger than life to small and subtle. Often faulty breathing, vocal tightness, and unhelpful movement habits interfere with full artistic expression.

The Alexander Technique helps the actor recognize his or her own habitual patterns that prevent him or her from transforming into another person. The Technique also develops kinesthetic and sensory awareness, which can lead to effortless coordinated movement, greater knowledge and command of breath and voice, genuine emotions, and consistent and sustained character choices enhancing the actor's performance.

The Alexander Technique is also useful to people who do other types of performance, including public speakers, religious leaders, and business people.
