The coronal suture of the skull (this would first have to be investigated) has—let us assume—a certain similarity to the closely wavy line which the needle of a phonograph engraves on the receiving, rotating cylinder of the apparatus. What if one changed the needle and directed it on its return journey along a tracing which was not derived from the graphic translation of sound, but existed of itself naturally—well, to put it plainly, along the coronal suture, for example. What would happen? A sound would necessarily result, a series of sounds, music…
Feelings—which? Incredulity, timidity, fear, awe—which of all feelings here possible prevents me from suggesting a name for the primal sound which would then make its appearance in the world…
Leaving that side for the moment: what variety of lines then, occurring anywhere, could one not put under the needle and try out? Is there any contour that one could not, in a sense, complete in this way and then experience it, as it makes itself felt, thus transformed, in another field of sense?
