Alright, everybody. The purpose of this tab is to familiarize the learner with the use of the C Major scale in 
the 7th position (my favorite way to play the scale). I, as a Christian, have learned guitar using various 
Christian music as practice pieces and was disappointed to see there is no tab for this wonderful song.
Here you go:

DISCLAIMER: This song is in 4/2 time, but I tabbed it as 4/4 (there's really no difference--just play the song
as you hear it in church.)

lyrics coutesty of namethathymn.com:

O Lord my God, When I in awesome wonder, 
Consider all the worlds Thy Hands have made; 
I see the stars, I hear the rolling thunder, 
Thy power throughout the universe displayed. 


Then sings my soul, My Saviour God, to Thee, 
How great Thou art, How great Thou art. 
Then sings my soul, My Saviour God, to Thee, 
How great Thou art, How great Thou art! 


When through the woods, and forest glades I wander, 
And hear the birds sing sweetly in the trees. 
When I look down, from lofty mountain grandeur 
And see the brook, and feel the gentle breeze. 


Then sings my soul, My Saviour God, to Thee, 
How great Thou art, How great Thou art. 
Then sings my soul, My Saviour God, to Thee, 
How great Thou art, How great Thou art! 


And when I think, that God, His Son not sparing; 
Sent Him to die, I scarce can take it in; 
That on the Cross, my burden gladly bearing, 
He bled and died to take away my sin. 


Then sings my soul, My Saviour God, to Thee, 
How great Thou art, How great Thou art. 
Then sings my soul, My Saviour God, to Thee, 
How great Thou art, How great Thou art! 


When Christ shall come, with shout of acclamation, 
And take me home, what joy shall fill my heart. 
Then I shall bow, in humble adoration, 
And then proclaim: "My God, how great Thou art!" 


Then sings my soul, My Saviour God, to Thee, 
How great Thou art, How great Thou art. 
Then sings my soul, My Saviour God, to Thee, 
How great Thou art, How great Thou art!

Anyways, that's it. Have fun playing; please comment/rate. God bless you!
