Okay, the song consists of a riff over the verses and then 
a simple chord progression for the chorus.  Here's the riff: 
 

    
        Abrir tablatura
        
    
    
------------------------------------------- 
------3---------3---------3-------3-------- 
----0---0-----0---0-----0---0-------------- 
--------------------------------0-------0-- 
--0-------0-2-------2-3-------3-----0h1---- 
-------------------------------------------
 
 
it's basically a C chord with a walking bass note. 
Play the riff over the verses. 
 
{verse} 
we sing the the nightingale song alive 
streets never border further than my sight 
we sing the nightingale song alive 
we might be different but our hearts won't lie 
 
{chorus} 
F 
And little ever changes 
Am 
If anything at all 
G                         C             G 
But the song sings loudly through these halls 
 
{verse} 
we sing the nightingale song alive 
we might be different but our hearts won't lie 
 
{chorus} 
F 
And little ever changes when you 
Am 
View it from the sky 
G 
The damage we encounter 
C 
The earth just passes by 
F 
And little ever changes 
Am 
If anything at all 
G                           C        G 
And we remind ourselves how small we are
