4.2.3 Implicit Aural Cognition: Gesture

Our understanding of the biological substrate of mind, and thus mentality, has been extended through the discovery of mirror neurons in the brain’s various sensory cortexes , including the premotor cortex which projects directly to the spinal cord, and the amygdalae clusters located deep within the temporal lobes that perform a primary role in the processing of memory, decision-making and emotional responses, as discussed.23 There is also a growing body of research in neuroscience that the aural conveyance of complexities such as most music, is reliant, at least to some extent, on an embodied interpretation (via performers) for effective communication with embodied listeners.24 It was not until it was technically possible to produce musical compositions of any complexity that could be heard without the assistance of human performers, that it was possible to meaningfully speculate on the extent to which a listener’s perception of the structural or emotional characteristics of a piece of music are dependent on, not just the notated abstract pitch-time structures, but the sound-encoded gestures of performers bodily realizing them.For many centuries, people learned to listen to sounds that had a strict relation to the bodies that produced them. Suddenly, all this listening experience accumulated during the long process of musical evolution was transformed by the appearance of electronic and recorded sounds. When one listens to artificially generated sounds he or she cannot be aware of the same type of concrete and mechanic relations provided by traditional acoustic instruments since these artificial sounds are generated by processes that are invisible to our perception. These new sounds are extremely rich, but at the same time they are ambiguous for they do not maintain any definite connection with bodies or gestures (Iazzetta 2000).
