Try Conrad Aiken. From "Palimpsest: The Deceitful Portrait":

Once, on a sun-bright morning,
I walked in a certain hallway, trying to find
A certain door: I found one, tried it, opened,
And there in a spacious chamber, brightly lighted,
A hundred men played music, loudly, swiftly,
While one tall woman sent her voice above them
In powerful sweetness. . . .Closing then the door
I heard it die behind me, fade to whisper,—
And walked in a quiet hallway as before.
Just such a glimpse, as through that opened door,
Is all we know of those we call our friends. . . .
We hear a sudden music, see a playing
Of ordered thoughts—and all again is silence.
The music, we suppose, (as in ourselves)
Goes on forever there, behind shut doors,—
As it continues after our departure,
So, we divine, it played before we came . . .
