I have had singing lessons and started having my voice training at the age of 17. Yes, it is true that in order to produce the sound that you want, you do not sing from your throat. You sing the notes through breathing through your diaphragm. In order to do this the best thing to do, is to place each of your hands on either side of your diaphragm and concentrate on just breathing from here. Once you have got comfortable just breathing from here, you will find it much more easier to sing and project your voice without singing the note through your throat. You have to sing the notes and feel them at the top in your head so that get resonance in your voice. By that word resonance, I mean that the sound you sing will be deeper and fuller which ocurs from the amplification of your voice by the bones of your head and your upper chest (diaphragm) and by the air cavities of the nasal passages.If you place an index finger tip on each temple, it makes it easier to imagine the sound coming through the top of your head. I have tried to answer this question the best way that I can and hope that it has helped to clarify the subject of voice projection for you
Excellent advice and I know because my Mum cut records with Columbia and used to teach singing having been Bel Canto trained herself. she had a four and a half octave range when she was singing professionally.
I know there is a particular way to emphasize the use of specific muscles, to project a better tone from oneself, while singing. For more detail, I would suggest you search of a truly wise Songstress, whose professional career is almost at an end.
To bother these people while they are still on top of their game, would be like a flea annoying a dog, and those people will disregard you, as though you don't matter, because they are too involved in their own self.
But, I would definitely seek out someone else, instead of trying to get subjective opinions from others, when professionalism is actually required.
use your diaphragm and sing out. milk, sugar, caffiene etc coat your throat so avoid those well before you sing. and dont gutterly clear your throat! it damages your vocal chords. as well dont sing through your nose. it sounds funny.
