Interiority designates the qualities of sound that do not refer to external causes/sources. It is close to what one hears during what Pierre Schaeffer called ’écoute réduite’ (Reduced Listening). When attention is drawn away from a sound’s exteriority, or reference, the ’reduced’ experience can be at least as full and complicated in its own way, including the perception of mass, grain, etc. - qualities of the ’interior’ of sounds.
