Asimov’s Visi-Sonor

He added, in a patent effort to manufacture light conversation, “You know how the beblistered thing works? I looked it up for this purpose, and all I’ve made out so far is that its radiations stimulate the optic center of the brain directly, without ever touching the optic nerve. It’s actually the utilization of a sense never met with in ordinary nature. Remarkable, when you come to think of it. What you hear is all right. That’s ordinary. Eardrum, cochlea, all that. But—Shh! He’s ready. Will you kick that switch. It works better in the dark.”

In the darkness, Magnifico was a mere blob, Ebling Mis a heavy-breathing mass. Bayta found herself straining her eyes anxiously, and at first with no effect. There was a thin, reedy quaver in the air, that wavered raggedly up the scale. It hovered, dropped and caught itself, gained in body, and swooped into a booming crash that had the effect of a thunderous split in a veiling curtain. 

A little globe of pulsing color grew in rhythmic spurts and burst in midair into formless gouts that swirled high and came down as curving streamers in interlacing patterns. They coalesced into little spheres, no two alike in color—and Bayta began discovering things.

She noticed that closing her eyes made the color pattern all the clearer; that each little movement of color had its own little pattern of sound; that she could not identify the colors; and, lastly, that the globes were not globes but little figures. 

Little figures; little shifting flames, that danced and flickered in their myriads; that dropped out of sight and returned from nowhere; that whipped about one another and coalesced then into a new color. 

Incongruously, Bayta thought of the little blobs of color that come at night when you close your eyelids till they hurt, and stare patiently. There was the old familiar effect of the marching polka dots of shifting color, of the contracting concentric circles, of the shapeless masses that quiver momentarily. All that, larger, multivaried—and each little dot of color a tiny figure. 

They darted at her in pairs, and she lifted her hands with a sudden gasp, but they tumbled and for an instant she was the center of a brilliant snowstorm, while cold light slipped off her shoulders and down her arm in a luminous ski-slide, shooting off her stiff fingers and meeting slowly in a shining midair focus. Beneath it all, the sound of a hundred instruments flowed in liquid streams until she could not tell it from the light. 

She wondered if Ebling Mis were seeing the same thing, and if not, what he did see, The wonder passed, and then– 

She was watching again. The little figures—were they little figures?—little tiny women with burning hair that turned and bent too quickly for the mind to focus?—seized one another in star-shaped groups that turned—and the music was faint laughter—girls’ laughter that began inside the ear.

The stars drew together, sparked toward one another, grew slowly into structure—and from below, a palace shot upward in rapid evolution. Each brick a tiny color, each color a tiny spark, each spark a stabbing light that shifted patterns and led the eye skyward to twenty jeweled minarets.

A glittering carpet shot out and about, whirling, spinning an insubstantial web that engulfed all space, and from it luminous shoots stabbed upward and branched into trees that sang with a music all their own. 

Bayta sat inclosed in it. The music welled about her in rapid, lyrical flights. She reached out to touch a fragile tree and blossoming spicules floated downwards and faded, each with its clear, tiny tinkle. 

The music crashed in twenty cymbals, and before her an area flamed up in a spout and cascaded down invisible steps into Bayta’s lap, where it spilled over and flowed in rapid current, raising the fiery sparkle to her waist, while across her lap was a rainbow bridge and upon it the little figures—

A palace, and a garden, and tiny men and women on a bridge, stretching out as far as she could see, swimming through the stately swells of stringed music converging in upon her— 

And then­–there seemed a frightened pause, a hesitant, indrawn motion, a swift collapse. The colors fled, spun into a globe that shrank, and rose, and disappeared.

And it was merely dark again.
