Twinkle, twinkle little star,
How I wonder what you are.
Up above the world so high,
Like a diamond in the sky.

When the blazing sun is gone,
When he nothing shines upon,
Then you show your little light,
Twinkle, twinkle all the night.

Then the traveller in the dark
Thanks you for your tiny spark:
He could not see which way to go,
If you did not twinkle so.

In the dark blue sky you keep,
And often through my curtains peep,
For you never shut your eye
Till the sun is in the sky.

As your bright and tiny spark
Lights the traveller in the dark,
Though I know not what you are,
# Twinkle, twinkle little star.

Written by Jane Taylor, published in "Rhymes for the Nursery" by Jane and her sister Anne, in 1804.

The repeat of the first two lines at the end of the verse came when it was set to music. For the tune, I have no information at all.
