The following text begins by recapitulating the results obtained in the Phenomenological Fragments on language by means of an approach to the essence of language through a hyperbolic phenomenological epoche that brings us to a preintentional realm of sense, which is called schematism of language. Such schematism constitutes a realm, in which the self is reflected in its infigurability both at the level of its selfaffection and its corporeality through what is called "perceptive" phantasiai, which are in turn transpositions of "primitive" phantasiai of the schematism outside language, as well as that which takes place in the exchange of glances between the newborn and the mother under the concrete model of the infantile babbling. This self-constitution through "perceptive" phantasiai will be transposed into "sketches of sense" that will keep the infigurable character of the former but transposing them in turn into "sketched senses", that is, into signs of a symbolically instituted language and whose sense making refers back to the making of sense from its origin. It is this infantile babbling that is called proto-musicality, and it is what constitutes that with which poetry and music "play" beyond their respective symbolic institutions.
