It is some foreshortening of perception wich can look like a specification of main named layers that can be used to create an algorithmic composition. Sequense of sounds can make a structure. Whole structure can be analyzed. If sequence is transformed in time, analyzing can find main active layers of transformations.
esthetics (this one is not a layer. It is necessarily different foreshortening)
