I also think pronunciation of a foreign tongue could be better taught than by demanding from the pupil those internal acrobatic feats that are generally impossible and always useless. This is the sort of instruction one recieves: 'Press your tonsils against the underside of your larynx. Then with the convex part of the septum curved upwards so as almostbut not quiteto touch the uvula try with the tip of your tongue to reach your thyroid. Take a deep breath and compress your glottis. Now without opening your lips say "Garoo".' And when you have done it they are not satisfied.
