Analysis of 'My Unfinished Song'

I hope those I love, don't get this all wrong
I've written many stanzas to my unfinished song
But all of a sudden; everything turned around
My soul is still speaking, but I don't hear it's sound.

My guitar sits un-dusted, my notepads untouched
My keyboard's outdated, my voice turned to rust.
Another sun rises but not really for me..
I wish I had found that one perfect key...

To open my heart and my soul and my mind..
All flowing together, at the very same time.
Maybe there's still time to turn this around;
And the next time my soul speaks; I will hear its sound.
