The author presents two pieces by Luigi Nono, Découvrir la subversion: Hommage à Edmond Jabès and Post-Prae-Ludium n.3: “BAAB-ARR”. No score exists for these pieces; they have only been performed by the original performers. Veniero Rizzardi discusses the placement of these pieces within Luigi Nono's oeuvre and the potential of notating them.
