This is the chord progression of Come Out And Play by Billie Eilish on Piano, Ukulele, Guitar and Keyboard.

[Intro]
C
Hmm, hmm

[Verse]
C                                F
Wake up and smell the coffee
C                              F
Is your cup half full or empty?
C                              F
When we talk, you say it softly
C        F          C                Am         C                F
But I love it when you’re awfully quiet, hmm, quiet

[Pre-Chorus]
C                              F
You see a piece of paper
C                              F
Could be a little greater
C                              F
Show me what you could make her
C       F       Am       C                F          C
You’ll never know until you try it
C                F                C
You don’t have to keep it quiet

[Chorus]
Am                Em                C
And I know it makes you ner-vous
Am                Em                F
But I promise you, it’s worth it
Am                Em                              G
To show ’em every-thing you kept in-side
C                    Em
Don’t hide, don’t hide
Am                Em                G
Too shy to say, but I hope you stay
Em               Am
Don’t hide a-way
C
Come out and play

[Bridge]
C                              F
Look up, out of your window
C                              F
See snow, won’t let it in though
C                                            F
Leave home, feel the wind blow
C                F                Am                C
‘Cause it’s colder here inside in silence
Am                F                C
You don’t have to keep it quiet

[Chorus]
Am                Em                C
Yeah, I know it makes you ner-vous
Am                Em                F
But I promise you, it’s worth it
Am                               Em                G
To show ’em every-thing you kept in-side
C                              Em
Don’t hide, don’t hide
Am                Em                G
Too shy to say, but I hope you stay
Em                Am
Don’t hide a-way
C
Come out and play
