for piano and 22 instruments

“Points on the curve to find …” sounds like one of the Chemins – perhaps because Berio initially composed the piano part, before adding the orchestral layers. The piece starts off in a great hurry, with an incessant tremolo in the piano, until the music abruptly halts just before the end. Berio explains the title this way: “ … the piano part alone (it is almost always homophonic) can be heard as a curve … on which the other instruments position themselves to reveal and interpret their harmonic characteristics – like a template or drawing, where one adds more lines at various points – they change the sense while also illuminating other latent aspects.”
