I'm glad you asked that Scorpio - I would like to know as well.

A couple of years ago it was suggested to me that I could improve my vocal ability if I got away from singing from my throat and moved the sound up to my face. I was given an exercise that involved placing my finger and thumb either side of my nose and feeling the vibration that came from saying 'nee nee nee nee'. After a few false starts I got the idea and found that there was a marked improvement in my singing voice - much louder and clearer.

In the past year or so, partially as a result of that change, I have been told, by a number of singers, that my singing voice has improved markedly.
