The song comes from the heart and when you sing the feeling you have for the music is found in your voice. With some people its just straight ahead with no frills with others it swirls and floats. Neither way is wrong, neither right. They both fit the people who sing in that fashion just right. If the way you imagine the song comes out with embellishments that's right for you, if the way you envision the song is simple and sparse that's it. I sometimes sing with more grace notes when I sing unaccompanied. When I sing with the guitar I usually am more straightforward. The song's the imporatnt thing, let the words and music carry it, just go along for the ride. Dan
