Sound Waves, And Friends Do Too.

The purple robot watched the human's fingers as she brought them up gently, and yet....?
Maybe the human was to tap on something, thereby creating a thumping sound. But where? On the strange dark cases everywhere? The hard wood of the stage? On her own hardware? No, she figured, that wouldn't be very wise. And tapping would require her to lower her fingers before she started.
So it couldn't be tapping - but what else? Earth physics were still strange enough to her, but she had grasped the concept of sound ages ago. It didn't just come from the air, like Shey apparently expected it to - something had to happen to make the sound.
Or maybe - and this was the reason that probably unsettled her, though it was unnatural for her to feel unsettled - perhaps Shey could alter the physics of this world and make sound from her fingers. Which, Violet did have admit, sounded outlandish - but then, another being could have the ears of a being far smaller than him. So, in the end, was it really all that strange in this world?
"Yes, please exemplify this concept."

Vi watched in rapt curiosity as Shey raised her index and middle fingers over her flattened left palm. Almost immediately, two little balls of light made themselves apparent (though faintly) next to her head, and as Vi analyzed the situation closer, she could only come to one conclusion - she was manipulating the frequency within the air. Quite an advanced skill for a human AI - they might have called it "magic". It very well could have been - to Vi, it was amazing. Still unable to summon the speech scripts from her memory at that moment, she only nodded, an intense look of curiosity on her face. What tech was this!?

If the lights had amazed Vi, it was certainly overshadowed by the sound coming from seemingly nowhere but her palms, evident by the look of sheer wonder on Vi's face. Strange enough... it wasn't voluntary - reflex, perhaps? It didn't matter, not right now - she was being confronted by a new piece of information. Shey herself did not sing, not physically - but words had been uttered, again seemingly from her palm.

"You have a useful gift," she mused aloud, looking impressed. "The concept is now very clear. Thank you."

Finally, something in the human's behavior that made sense to Violet's processing systems - a want. "The same is true for myself," she told Shey matter-of factly, as the purple robot sat abruptly on the ground, a thunk of metal on ground.
"Your face is of an odd coloring - it is reddening." Violet pointed out, looking impassive.
It was then that she sensed the other beings in the park moving forwards, gathering around the primitive stage to watch the human perform. Vi stopped for a second. Did the human say she could listen to her auditory performance? If so, then she would be honored to - communicated via a big, sort of weird nod of the robot's head. "Yes, I would like very much to witness an auditory performance. "

Vi, upon taking in the act and deciphering its meaning from her databases, finally giggled at Shey, a hand placed in front of her mouth. "You are incorrect - your face is indeed taking on a red color." She believed this is what was called "blushing"... Yes, she was almost certain. But the cause? Indeterminate. She had seen some humans execute "blush" emotion in response to a compliment.... Perhaps it was the compliment?

Whatever the matter, it was evident that the people around the stage were starting to get impatient, as they waited for the apparently-scheduled concert. Violet wondered why they hadn't yet seen Shey. Was she only visible to a certain number of beings?

She was questioning things much too frequently. Nodding her head, she replied with a demure "That is adequate, yes. I will enjoy this performance." She glanced at the instruments on the ground, then back to Shey, a smile spreading across her metallic features. "Be in the possession of good luck! Do not break your leg appendages, as that would cause pain."

"Not at this point in time," replied Violet. "Suggestions currently unavailable, for I do not know of much music in this world. Conversely, I shall do as you asked, and perform the 'sit' action in the first row of chairs." Violet noticed many things - for instance, though the human denied it, her face still sported a shade of red attributed to a "blush", and the stutter in her voice indicated shyness.
Oh well. At least she promised she would not break either of her "leg".appendages. It was probably better for her software.
