F. M. Alexander concluded that the orientation of the head in relation to the body determines the quality and successful response of how all other intended bodily motion may occur. The head is a steering key to bodily movement. Later, other Alexander Technique teachers used additional tems to encourage and mark the importance of this head movement. Alexander's first graduate of this first training course, Marj Barstow, originated the phrase: "the head moves, and the body follows."
