the sound "r." Rudolf Steiner has provided a series of drawings later color enhanced depicting the motions of the eurythmist corresponding to each sound. For the sound "r" the arms roll forward somewhat like a wave.
Illustration 2. Here we see depicted the essence of Bely's work and his contribution or expansion of the theory and practice of eurythmy. Just as the eurythmy dancer gestures to depict individual sounds, so too does the tongue dance in the cavity of our mouths to describe a unique design or pattern.
the sound "s" For the sound "s" the right arm describes a snake like "S" movement from top to bottom
the sound "b" ... gestures for "b" Bely's description of the sound itself corresponds to the bilabial stop sound /b/. Here as far as I can discern Bely's description diverges from current eurythmic practice in which the sound "b" is represented by a gesture of embracing, encircling with the arms and bringing them close to body. Bely may have transcribed this sound incorrectly. The actual motions correspond to the the German "w" as in "Wasser" which is pronounced like the English sound "v" in "vision." The Russian sound [v] is represented by the Cyrillic letter "B".
the sound "p" This drawing for this sound has the arms bent more distinctly and outstretched at two 90 degree angles, somewhat like an Egyptian dancer.
lingua linguaraum I have decided on a Latin substitute to convey the special and essential for Bely's work multiplicity of meanings: The Russian phrase can be translated as tongue of tongues or language of languages. In Russian the word [iazyk] for "language" is the same as the word for "tongue." The Russian word is also related to the Indo-European root found in Latin "lingua" "language or tongue." The English "tongue" is related to the older Latin "dingua," and IE dnguha "tongue". The use of "tongue" for "language," for example the ability of the Apostles "to speak in tongues," i.e. many languages, is acceptable in some but not all English contexts. Here again Bely relies primarily on the association, equivalence, in Russian to identify "language" with one's "tongue." It is the movement of the tongue that will become essential in the (re-)creation of his special language. Teutonic *tungon is cognate with Old Latin dingua.
