Knock knock. The 4th Notation is almost a knock knock joke. The opening motif is kind of a knock knock theme. How many times do you hear it in the entire piece? Each time it appears, it is met by an ever changing, somewhat erratic reply. Listen to how it changes every time the theme appears. This interplay between static and erratic, constant and changing, is the core of this movement.
