Is it possible to somehow strengthen ones voice? Or are you just born with a crappy voice and you have to live with it...? I just think my voice doesnt have enough power. I think I can sing well however.
are you kidding...... of course you can do vocal exercises to strengthen your voice...................... I don't know a serious vocalist who doesn't.....here is a link with some useful information
the best way i have found is ......use it..simple....sing all the time..by yerself...in the car...but do it loud like if you were singing into a mic...i know it sounds stupid..but its easy and it works...
