[Riff 1] x1

[Riff 1] x2 w/ lyrics:

I am born; I am me.
I am new; I am free.
Look at me; I am young.
Sight unseen; Life unsung.

[Riff 2] x5

[Riff 3] x2

[Riff 3] x2 w/ lyrics:

My eyes have just been opened and they're opened very wide.
Images around me don't identify inside.

Just one blur I recognize, the one that soothes and feeds.
My way of life is easy, and as simple are my needs. [strike A5]

[Riff 4] x2

[Riff 4] x2 w/ lyrics:

Yet my eyes are drawn towards the mountain in the east.
Fascinates and capitaves; gives my heart no peace.

D                                C
The mountain holds the sunrise in the prison of the night,

D                                     C         Fmaj7
till bursting forth from rocky chains, the valley... floods...

G6
with light.

[Riff 3] x2

[Riff 3] x2 w/ lyrics:

Living one long sunrise, for to me all things are new.
I've never watched the sky grow pale, or strolled through fields of dew.

I do not know of dust to dust, I live from breath to breath.
I live to climb that mountain to the Fountain of Lamneth. [strike A5]

[Riff 4] x2

[Riff 4] x2 w/ lyrics:

Yet my eyes are drawn towards the mountain in the east.
Fascinates and capitaves; gives my heart no peace.

D                                C
The mountain holds the sunrise in the prison of the night,

D                                     C         Fmaj7
till bursting forth from rocky chains, the valley... floods...
