[C]Twinkle, twinkle, [F]little [C]star,
[Dm]How I [C]wonder [G]what you [C]are!
[C]Up a[Dm]bove the [C]world so [G]high,
[C]Like a [Dm]diamond [C]in the [G]sky.
Twinkle{\ldots}

[C]When this blazing [F]sun is [C]gone,
[Dm]When he [C]nothing [G]shines u[C]pon,
[C]Then you [Dm]show your [C]little [G]light,
[C]Twinkle, [Dm]twinkle, [C]through the night.
Twinkle{\ldots}

[C]Then the [F]traveller in the [C]dark
[Dm]Thanks you [C]for your [G]tiny [C]spark;
[C]He could [Dm]not see [C]where to [G]go,
[C]If you [Dm]did not [C]twinkle [G]so.
Twinkle{\ldots}

[C]In the dark blue [F]sky you [C]keep,
And [Dm]often [C]through my [G]curtains [C]peep,
[C]For you [Dm]never [C]shut your [G]eye
[C]Till the [Dm]sun is [C]in the [G]sky.
Twinkle{\ldots}

[C]As your bright and [F]tiny [C]spark
[Dm]Lights the [C]traveller [G]in the [C]dark,
[C]Though I [Dm]know not [C]what you [G]are,
[C]Twinkle, [Dm]twinkle, [C]little [G]star.
Twinkle{\ldots}
