There is a simple melody in the intro and inbetweens on the C chord mostly.
[Intro]
C F (x4)
[Verse]
C C/E F C
When you think you've seen it all, through tears in your eyes
C C/E F G
Your head hanging low, the moon on the rise
F C E7 Am
Well I think of you, yeah I pray for you
C G F C
May your days pass like Sundays, may your nights lay you down
[Chorus]
F C
Let your heart not be troubled
F C
Cast your doubts to the wind
F Am
Lay your chains in the rubble
G F C F C F
Let your heart not be troubled anymore
[Verse]
C C/E F C
Well your bed sheets grow cold, every now and again
C C/E F G
Each stone in the road, a place where we've been
F C E7 Am
But where are we now, tell me, where are we now
C G F C
Lay your dreams on my pillow, and we'll get there somehow
[Chorus]
F C
Let your heart not be troubled
F C
Cast your doubts to the wind
F Am
Lay your chains in the rubble
G F C C7
Let your heart not be troubled anymore
[Bridge]
F C E7 Am
Well sometimes a love comes undone in the wind
F C C G
And you can't see your shoes, where you goin, where you been
F C E7 Am
So I'll wait around right here, so I don't lose my way
D7 G G G7 G7
I never had no direction anyway
[Chorus]
F C
Let your heart not be troubled
F C
Cast your doubts to the wind
F Am
Lay your chains in the rubble
G F
Let your heart not be trouble
F C
Let your heart not be troubled
F C
Cast your doubts to the wind
F Am
Lay your chains in the rubble
Dm C
Let your heart not be trouble
F G
Let your heart not be trouble
F G C F C F C F C
Let your heart not be trouble anymore
