The Anatomy of Directing (30min):
A nice, short, downloadable free e-book by Ted Dimon, an Alexander Technique teacher from NY.
It has several mini-movement and body mapping experiments an comes with a few pictures. You can read it and test out the experiments in each section a chapter at a time.
I think most is too advanced for brand new students; dependent on your experience/ background/ motivation-level. Still, a useful and worthwhile quick read.
Don't forget to actually try it out and figure out why (or why not) it's working for you. Alexander Technique knowledge without application is not the Alexander Technique.
Much thanks to Ted Dimon for sharing this work,
