This is the chord progression of Dreamer by Martin Garrix on Piano, Ukulele, Guitar and Keyboard.

A#m, Db, Fm (x2)
I’m a(A#m) dreamer
Don’t (Db)tell me not to dream
I got (Fm)freedom
(Fm)And that’s everything to me
It don’t (A#m)matter
What(Db) I’ve got or where I go
I’ll find (Fm)shelter a million miles from home
It ain’t (A#m)easy to keep (Db)going when it’s hard
Keep(Fm) shining in the dark
When you wanna fall apart
But I’m a(A#m) dreamer
So don’t(Db) tell me not to dream
I’m a(Fm) believer

As long as I got something to (A#m)believe in
As (Db)long as I got something to (Fm)believe in
(Fm)As long as I got something to (A#m)believe in
As (Db)long as I got something to (Fm)believe in
(Fm)As long as I got something to (A#m)believe in

A#m, Db, Fm (x4)
I’m a (A#m)lover
Don’t (Db)tell me who to love
I’m a(Fm) runner
(Fm)’Cause I’ve got somewhere to run
I just (A#m)listen to the(Db) voices in my head
When they (Fm)tell me
(Fm)I’ll always have something to believe in
As long as I got something to (A#m)believe in
As (Db)long as I got something to (Fm)believe in
(Fm)As long as I got something to (A#m)believe in
As (Db)long as I got something to (Fm)believe in
A#m, Db, Fm, (x4)
