No matter how many times I hear this music, it always feels fresh. A sure sign of genius.
After you've watched it once or twice (and thrown out your kleenex), get still and quiet.
The piece builds perfectly for this particular exercise.
Find a very, very simple movement. Repeat, repeat, repeat.
Breathing with either closed or soft eyes.
Keep repeating the movement until it changes itself. Do not change the movement. Observe it changing.
