The most frequent form taken by Bernard Heidsieck's book publications is a hybrid form : the book-disc. I propose to examine, the first occurrences of this book corpus, what allows to apprehend the poetic project in its mediological complexity, but also insofar as the inclusion of sound produces specific questions from the editorial point of view, and, consequently, shifts in the poetics of the creative book, whether it be "dialogue" or "artist". This article thus considers the different ways of including sound in the book, through the typed score, the graphic transcription, or the addition of heterogeneous mediums within the book space itself, as many new solutions questioning the book in its materiality and its limits.
