Silent song

There's a song I wish to sing
But it's out of tune and out of reach
It belongs to no one, not even me
And yet I hope it gave me wings

But all this silence will make do
For the absence I've come to know
And that song will be my voice
For tomorrow or forever more

And should you ever hear me sing
Let me know or hold your peace
Join the chorus, if need be
And pour your love out to me
