About "Erratum Musical": "Duchamp composed a music piece en famille, Erratum Musical, by using chance operations. [...] it was precisely that kind of simplicity that Duchamp liked, drawing jumbled notes at random from a hat. Duchamp composed Erratum Musical with his sisters Yvonne and Magdeleine, seventy-five notes picked by chance to accompany as many syllables of the randomly chosen dictionary entry for imprimer." - Sylvère Lotringer, "Becoming Duchamp"
