Movement IX is broken up into three large sections, with the third being broken up further into a number of smaller fragments. The first large section includes variations of quotations from the central movements of all three cycles (movements III, V, and VI) along with the text from movement 5. The movements are quoted in reverse order (i.e. VI, V, III), and each time the text from the quoted movement is combined in some way with the text from movement III. The second large section, also the main section of the movement, includes a voice part without text and is built on a similar set of PDAs as the second cycle of "Marteau" while also drawing on movement V. The harmony for this section is interesting in that Boulez entirely avoids minor seconds as well as minor thirds (though their inverse, major sixths, are used instead). Unisons are used very rarely . The third section of movement IX serves as both a coda to the movement and to the piece. It is scored only for flute and percussion.
