The fifth and last string quartet of the great composer, musician and poet Giacinto Scelsi, written in 1984 in memory of his friend Henri Michaux who has just died, which is his last work, stripped, austere, is based on a Fa that fades between a white noise, and that reappears at the end in a vibrato that is the composer’s last breath. His music, Michaux will say, «is magnetized by the ineffable». This quartet constitutes an austere and naked funerary wake, with an overwhelming effect, a testament of Scelsi himself. The composer and poet die two years later than Michaux, taking with him all the secrets of his creation. Song of the swan that precedes the final silence of death, symbolized by the two empty, white pages that close their poems. These white pages constitute in Mallarmé a self-referential Nothing: «Sur le vide papier que la blancheur défend». The viaggio al centro del suono to which Scelsi aspired leads the musician poet to the death of the verbal images and the return to silence of the white surface of the page: «suddenly the white surface», he writes in one of his poems. Annihilatio mystica in the form of a blank page that in the three authors –Mallarmé, Michaux, Scelsi– leads to a wisdom of emptiness.
