The very first etude hits you with a visual shock. The right hand is in 4/4. The left hand is in 3/4. They play white keys and black keys simultaneously, drifting out of sync like two broken music boxes. The PDF looks like two different pieces glued together.

That is the world of .

These etudes are not "fun" to learn. They are frustrating, humbling, and physically exhausting. But the first time you successfully execute the polyrhythms of Automne à Varsovie (No. 6) without stopping, you will feel like you have hacked the matrix.

Ligeti was obsessed with the music of Conlon Nancarrow (player piano rolls). He tries to replicate mechanical canons where the two hands are slightly out of phase. Try counting this: the left hand moves in a 4:5 ratio against the right. Your brain will hurt. A Practical Tip for the PDF If you have acquired a legal copy of the score, do not just print it on standard paper. Take the PDF to a print shop and have them blow it up to A3 (or Tabloid 11x17).
