Music in memory is auditory imagery, a form or pattern of thought.
Consider being unable to access recorded music for an extended period of time-- or actually choosing not to do so-- and the possibility of a resulting change in perception of sound, auditory memory, and consciousness itself.
Numerous implications come to mind in regard to such a situation, with respect to clarity of thought, accuracy of memory, capacity to listen with various degrees of attention, and changes in point of view or other conditions of the psyche.
Postulate, then, music composed to reflect the perceptions of sounds as they are encountered in journeys through myriad surroundings. Such music is not meant to represent the environmental sounds themselves, but to allude to the ways in which they are apprehended as they occur naturally, through both active listening
and passive, or less intense, hearing
Transformation ambient music designed in this manner neither dominates consciousness nor leaves the listener to later experience the sensory illusion of involuntary audio imagery. Rather, it enhances atmospheres, stimulates perception and the imagination, and elevates the listening experience itself.
