I have sung as a performer many times..the only way I can do it is by being a character.
If the character has a pretty good voice, so do I (after far more practice and rehearsal than a naural singer needs).
I think singing is terrifying without a character.
I am so impressed that you are doing this, GE. Singing from your own voice...WOW. Please do post as much as possible on this.
Even metaphorically making sounds that may have echoes to the heart for others is such a worthy thing to do.
[[so I do not care what you sound like, in your own voice, to yourself. I care, insanely, that you just dare to do it. ANd I suspect that once you give yourself a break and DON'T listen to yourself for a while, you will be amazingly moving.
OK, so you have to sing on pitch, but if you can do that, GE, just from what I know of you, you will be so moving.]]
This applies to writing, and acting, too.
