I have come to believe, or think, or understand, that when someone dies, the most acute sense of loss is that of his or her voice. (For a while, one can “hear” a person’s voice in one’s inner ear, but slowly that fades.) This is odd, since sound is of course immaterial; one would think that the body would be the most felt absence. But sound is a distinctive marker of living presence more than any material object can possibly be; sound and lived time are indissoluble: they are, so to speak, part of the continuity of a landscape rather than the singularity of a portrait. Sound is embedded in spatial context.
