listen to your very favorite performers and ask yourself what it is about them that you like.....chances are, it's style and projection and 'flavor'...not just technical perfection. I have heard singers with perfect enunciation who had no 'life' in their singing, and blazing fast banjo & guitar pickers who sounded like a piano roll. I'd rather hear Norman Blake play "Black Mountain Rag" than .....well, than a couple others, because he 'feels' what that melody is doing.

And Jeannie Robertson was right...some singers TELL the story..(did you ever watch some ballad singers close their eyes so they could move 'into' the song and not be distracted by the people listening?)

finally, record yourself and listen to it and critique it as if it were NOT you....
