I. The Forming of Speech as Art

The absolute opposite of a is u (oo). When you say u, then beginning from the mouth you contract the speech organs, wherever possible, before you let the sound go through. The whole speech organism is more closed with u than with any other vowel sound. There then you have the two contrasting opposites: a u. Between a and u lies o. O actually includes within it, in rightly formed speech, the processes of a and the processes of u; o holds together in a kind of harmony the processes of opening out and the processes of closing up.
