The Stylistic Perception of a Musical Work: An Experimental and Anthropological Approach
The idea of change involves the perception of this relationship between the "before" and the "after", the perception of a contrasting series which introduces a fractured time into the continuous flow of music. This fracture-relationship, passing from state A to state B, constitutes the basis for the perception of musical structures. The auditory process arranges every musical work into "sections" of varying lengths, demarcated by the fact that each presents, in their relationship to the preceding section, a different quality. In a way, the change from one section to the next introduces a discontinuity between two delimited and differentiated sound groups, each of which in itself "achieves a form of synthesis almost static in its evolution" (Fraisse, 1957).
