The Abandoned Music Box

The little ballerina lived in a beautiful house made of wood. There was nothing in it; in all honesty her small home was bare, save for herself. It was a dark, cold place, and she could never see past a centimeter.

When her beloved opens the door and shower her with light, however, she dances. She rises from her miserable position and stands tall and poised, and the moment that gentle melody plays, she moves.

Softly and gently, with grace and a kind of joy experienced by few.
Her harmonious steps spoke of love and bitterness, of hope and of pain; her elegance enchanted many, and her beauty and humble nature won her grand praises.

Yet she cared for no one but her beloved; the one man who has now forgotten her, and left her all alone in that dreary darkness. He rarely opens the door anymore, but she still waits patiently for the man who used to watch her all day long, and show her off to all his friends.

No matter how long it takes, she will wait, and she will always be ready to rise in glory and dance once more...

In the dimmest corner of an abandoned room, the little music box sat atop a dusty, rotting table.

Correct me if I'm wrong, but one of the elements of the story is "the twist" about how it's not a person but a music box, right? Unfortunately for me, I "got it" after the first sentence of the second paragraph =(. All I could think of as I read the rest of the story is confiming my hypothesis, and didn't concentrate on your writing. I suggest changing the title lol.

Maybe make it a bit more personafied as well... "When her beloved opens the door and shower her with light, however, she dances." seems very automatic. Maybe that's your intention, but it's part of what gave it away for me so soon. Maybe show more thoughts, and show events less in A happens so B happens, and more in A happens, she thinks about it, and does B. Something like "Every day, in that darkness-filled room, she rehearses her dance on the stage of her mind. All for that shining moment when her beloved opens the door, and she could thank him with that dance she has practiced so oft. That perfected dance. It always brought a smile to his face, after all."

Maybe that's a bit too much... but I think it makes the music box sound more human. you can definitely embellish the language all you want... I'm glad you kept it concise, but if you want that fairy-tale feeling at the beginning to get the reader to suspend their disbelief (after all, it's a bit weird to always be in a dark room) until the reveal, more flowery language could help...
