  The bottom line represents a continuous stretch of sensory experience, a continuous auditory tone, let’s suppose. This stretch of experience is apprehended by dense succession of momentary acts, represented by the full-length vertical lines. (Only a three of these are shown here, in reality there would be an infinity of them.) Focus first on D and the vertical line standing on it: D-A***. This line represents the content apprehended by the momentary act occurring at D, and hence a single specious present. This act’s content represents the tone segment A-D, but the act does not embrace the entirety of A-D itself – we are no longer dealing with acts of awareness which reach back to the recent past. Instead, the act apprehends a content possessing parts which seem more and more past (or less and less present) as we move from D to A***. In the figure, the greater the number of asterisks affixed to a content, the less presentedness it possesses. Hence the same tone-segments occur in successive specious presents with smoothly decreasing degrees of presentedness. If we simplify by first considering momentary tone-phases, the phase at A is experienced as A* in the specious present at B, as A** in the specious present at C and finally as A*** in the specious present at D. In a similar way, D is experienced as D* in the specious present occurring at E, and then as D** in specious present occurring at F. Extended tone-segments (e.g. B-C) behave in the same manner, being experienced as B**-C* (at D) and B***-C** (at  E).[19]
