Capo on 2nd:

[Intro]
Eb
Where did she go?
F
Where can she be?
Eb
When will she come again
F
Calling to me?
           Am
Calling to me...

Am      F     Am     F

[Verse 1]
Am
Somewhere there's a girl
Am                                          D
Who's like the shimmer of the wind upon the water
Am
somewhere there's a girl
Am                                            D
Who's like the glimmer of the sunlight on the sea
F
Somewhere there's a girl
             C/E              D
Who's like a swell of endless music
F
Somewhere she is singing
        C/E               Bb   G
And her song is meant for me

[Chorus]
        C
And her voice
                     F
It's sweet as angels sighing
        C
And her voice
                    Em  F  G
It's warm as summer sky
         C
And that sound, It haunts my dreams
    F
And spins me 'round
   C/E
Until it seems
    D          G
I'm flying...
    Am     F
Her voice!

[Verse 2]
Am
I can sense her laughter
Am                                     D
In the ripple of the waves against the shoreline
Am
I can see her smiling
Am                                    D
In the moonlight as it settles on the sand
F
I can feel her waiting
       C/E              D
Just beyond the pale horizon
F                        C/E           Bb     G
Singing out a melody too lovely to withstand

[Chorus]
        C
And her voice
                      F
It's there as dusk is falling
        C
And her voice
                          Em   F   G
It's there as dawn steals by
         C
Pure and bright, it's always near
    F
All day, all night
    C/E             D          G
And still I hear it calling...
    Am      G    F
Her voice

[Outro]
F
Strange as a dream...
G
Real as the sea...
F
If you can hear me now
G
Come set me free...
                       Am     F
Come set me free!

Am     F     G     C
