Pretty much the same chords throughout the whole song
D, Em, Bm7, G
Do you ever feel, feel so paper thin
Like a house of cards
One blow from caving in
Do you ever feel already buried deep
Six feet under scream
But no one seems to hear a thing
Do you know that tehre's still a chance for you
Cause there's a spark in you
[ Tab from: https://www.guitartabs.cc/tabs/k/katy_perry/firework_crd.html ]
You just gotta ignite the light
And let it shine
Just own the night
Like the Fourth of July
Cause baby you're a firework
Come on show 'em what your worth
Make 'em go "Oh, oh, oh!"
As you shoot across the sky-y-y
Baby you're a firework
Come on let your colors burst
Make 'em go "Oh, oh, oh!"
You're gunna leave 'em fallin' down-own-own
You don't have to feel like a waste of space
You're original, cannot be replaced
If you only knew what the future holds
After a hurricane comes a rainbow
