1) on the low E and A strings
A|-2-0------2-0-----|
E|-----3-2------3-2-|

2) I prefer to play it using power chords- or you could use any other
   chords you can think of
   The riff just goes B- A- G- F# X2
E|-------------------|
B|-------------------|
G|-4-2------4-2------|
D|-4-2-3-2--4-2-3-2--|
A|-2-0-3-2--2-0-3-2--|
E|-----5-4------5-4--|

3) Or you can get away with just strumming the Em chord
Terry Jacks- Concrete Sea (1972)

[Intro or Refrain]

[Verse 1]
Em                       C
I heard some music being played today
D                      Em
I heard a song but the words were wrong
Em                     C
It didn't matter to me anyway
D                             
Some people really don't care what they say

[Verse 2]
Em                       C
I started looking to the sky today
D                              Em
'Cause it's so big and it's so far away
Em                       C
I've got too many things inside my head
D                          [Refrain]
I wish that I could be up there instead

[Chorus]
Em        G
No one is meant to be
Am               Em
Living here in a concrete sea
Em        G
Everyone, including me
Am                 [Refrain]
Wishes he could be set free

[Verse 3]
Em                         C
And then I looked into the ocean blue
D                               Em
'Cause it's so deep and it's so quiet too
Em                           C
There's just too many people everywhere
D                   [Refrain]
I wish that I was down there

[Chorus]
Em        G
No one is meant to be
Am               Em
Living here in a concrete sea
Em        G
Everyone, including me
Am                 [Refrain]
Wishes he could be set free

[Verse 4]
Em                    C
I heard a story being told today
D                         [Refrain]
About a man and just how he got away
Em                              C
You got to leave the things you grow up for
D                            [Refrain]
Turn your head and start to swim for shore

[Chorus]
Em        G
No one is meant to be
Am               Em
Living here in a concrete sea
Em        G
Everyone, including me
Am                 [Refrain]
Wishes he could be set free

Em        G
No one is meant to be
Am               Em
Living here in a concrete sea
Em        G
Everyone, including me
Am                 [Refrain]
Wishes he could be set free
