Gestures of sound combine: with a touch of the tongue and a
spiral of the stream (expansion, contraction, concentration of
the flow) the composition of lines of the stream with the tongue
is -- the union of the body and the arms; for the sound "l'":
the tongue is raised; the surface touches the palate; with a tap
against the palate the stream is broken up; it falls downward;
and being reflected, it rises a second time and -- as I am
bending over, I lower my arms downward: I raise them anew; for
the sound "u": I close my arms in an angle; "n" is -- a light
movement of the body; the movement of the arms is exactly the
same; the gesture -- of touching -- is like the touching of the
tongue of the upper cavity of the mouth with a very light stream
overtaking the tip; "a" is -- the spreading apart of the arms.
