Lyrics

Do you ev er feel like a plas tic bag drif ting through the wind, want ing to start a gain?

Do you ev er feel, feel so pa per thin, like a house of cards one blow from cav ing in?

Do you ev er feel al read y bu ried deep, six feet un der, scream but (C)no one seems to hear a thing?

Do you know that there’s still a chance for you ’cause there’s a spark in you?

You just got ta ig nite

the light

and let

Just own

the night

like the Fourth of Ju ly.

’Cause ba by, you’re a (G)fi

re work.

Come on, show ’em (Em)what

you’re worth.

Make ’em go (G)“Oh, oh, oh!” As you shoot a cross the (Em)sky y y.

Ba by, you’re a (G)fi

re work.

Come on, let your (Em)col

ours burst.

Make ’em go (G)“Oh, oh, oh!” You’re gon na leave ’em all in (Em)awe, awe, awe.

Easy piano arrangement in the key of G at 126 BPM. Difficulty: beginner. Color-coded notes — no sheet-reading skill required.

Teacher’s notes

This arrangement is a great way to lock in five essential pop chords — G, C, Em, Am, and F — over a steady pedal bass in your left hand.

That pedal pattern means your left hand mostly holds or repeats a single low note while your right hand moves through the chord changes, so start hands-separate: get your right hand comfortable with each shape before adding the bass.

The transition to watch is any move involving F, since it's the one chord borrowed from outside the key of G and it'll feel slightly unfamiliar under your fingers.

At 126 BPM the energy is brisk, so slow it down to around 90 first and loop the verse progression until the changes feel automatic.

Once you bring it up to tempo, you'll notice the momentum almost carries you — and you'll walk away with a rock-solid feel for the I–V–vi–IV pattern that powers half of modern pop.
