By exploring Deleuze’s theory of the creative act, I suggest in the first part of this article that all art forms can achieve a generalized musicality. This musicality denotes a region of perception that goes beyond ordinary senses, with which we can come into contact either by creating or by witnessing art. In the second part, I illustrate the possibility that this doctrine opens for a musical literature, i.e. a literature able to achieve the generalized musicality, with some fragments of surrealist literature. I conclude with the idea that the doctrine at hand could constitute an evolution and a radicalization of surrealist aesthetics.
