Yes, the Alexander Technique is by far best known among musicians and actors, so much so that for many years it was thought of as an acting practice. (Of course Alexander himself was an actor and developed his technique while figuring out why he had lost his voice.) I think this is because these professions have a lot to do with how body and consciousness work together, and this is the area in which AT is very practical. To some people that might sound like gobbledygook, but when your profession depends on it you quickly go with what's practical.

The teacher I like best (who's in the San Diego area) told me that her dream was to get more athletes to realize how much they could get out of it.
