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,
Then you show your little light,
Twinkle, twinkle, all the night.
Twinkle, twinkle, little star,
How I wonder what you are!

Then the trav'ler in the dark
Thank you for your tiny spark;
How could he see where to go,
If you did not twinkle so?
Twinkle, twinkle, little star,
How I wonder what you are!

In the dark blue sky you keep, and
Through my curtains often peep,
For you never shut your eyes,
Till the morning sun does rise.
Twinkle, twinkle, little star,
How I wonder what you are!

As your bright and tiny spark
Lights the trav'ler in the dark,
Though I know not what you are,
Twinkle on, please, little star.
Twinkle, twinkle, little star,
How I wonder what you are!
