Ligeti's piano Etudes possess a striking ability to suggest. The sonorities go beyond a mere polyphony and, surprising and unusual, they trigger in the listener's imagination both ephemeral and persistent images and at times sequences of such images, like the successive episodes of a narration or the scenes of a play. Ligeti's music is not a programme music, nor are the Etudes simple atmospheric evocations. They go beyond that. They are so to speak 'dramatised' in a virtual theatre on the stage of which speakers, mimes, tumblers and clowns alternate, or an imaginary movie screen where the machines so dear to Ligeti's heart turn frenetically as in Fanfares or menacingly as in Désordre.
