Twinkle, twinkle, little star.
Twinkle, twinkle, little star, how I wonder what you are.
Up above the world so high, like a diamond in the sky.
Twinkle, twinkle, little star, how I wonder what you are.
When the blazing sun is gone, when he nothing shines upon.
The you show your little light, Twinkle, twinkle, little star
Twinkle, twinkle, little star, How I wonder what you are.
Twinkle, twinkle, little star, how I wonder what you are.
