The thing about playing guitar is that you're not much use unless you can sing. All of my years playing the piano and no one ever expected me to sing along with any of the songs I played. But as soon as I picked up my guitar I felt compelled to sing along with it. And who really wants to hear you play the same arrangement (on the guitar) over and over until the song is complete, unless they can hear the lyrics too?
So I have been struggling with this idea lately. Can I really sing for other people? Exposing your voice, especially if you never had been and probably never will be thought of as a singer, is extremely, extremely frightening. It is probably one of the most vulnerable feelings I have ever experienced. There I am, behind my guitar, trying to decided whether or not I should let my naked voice show.
It's really a hard thing to do.
