Structures of Pierre Boulez

  I think it is a good idea to listen the piece with the score, will help you to understand the "structures" better. I was thinking why he called it structures, is there any special structures in the piece? Because from what I listened, I can hardly tell the structure of the music, I try to predict what is gonna happen in the next bar. it is an intersting piece that full of vitality, sounds like two kids are playing with each other,one  runing after another.
