I'm a 19 years old male and my (singing!) range is F2-B3, although my I can get down to D2 when I am relaxed.
My friends and I are singing sometimes and then I am mostly the deepest voice.
The weird thing is, that when my friends are singing for instance a C3 or a B2 it sounds very deep that I start to hit a F2 or G2, to sound as deep. But then I realize that I have to go up many notes - which was irritating at first, as my C3 or B2 sounds like a high note compared to the C3 or B2 of the guy next to me... I hope you know what I mean.
The guy next to me has just more volume, so more "in the chest"! When I am singing the same note, it sounds more straining, more "in the throat".
Does anybody of you know some advice how I can improve my volume? Is it about being relaxed?
