Here's download link for a 2 page reference sheet on key Alexander Technique principles/ jargon.
Alexander Technique Principles... are ingredients that make up the Alexander Technique. With practice you learn to understand and use them in new and creative ways to create the conditions for new movement and actions to show up. Have fun, and when lost, come back to principle.
Heads-up, this particular reference sheet has way too much info on it. It's recommend for students who have taken at least 10 lessons in the Alexander Technique, have some handle on what these terms mean from an experiential viewpoint, and are seriously motivated. If you haven't had a chance to do these things yet no worries, there's other info on the blog that will be a better use of your time.
