I KNOW WHAT YOU NEED!!!!!!
YOU NEED TO START EXCERSIZING YOUR VOCAL CHORDS, YOUR DIAPHRAGM, AND YOUR LUNGS. THAT'S WHAT I DID WHEN I WAS IN CAROUSEL.
I'll tell you a little story, if your familiar with Carousel then you know the song You'll Never Walk Alone, which is a very hard song to sing. Well when I joined the cast I only took 2 small, non-singing roles, because I can't sing. Well, half way through our rehearsals I had to take on the role of the principal and he has to sing You'll Never Walk Alone with the rest of the cast at the Graduation scene at the end.
So, of course I was horrified. I can't sing and now I was being thrown into the hardest song, vocally. Well, we had a great musical director/vocal coach and after a couple of weeks of breath excersizes and vocal excersizes I hit that last note and held it for the 15 seconds with no problem.
So hears a couple tips:
1) Breathing Excersize: take as deep a breath as you can in 4 seconds then slowly release for 12 seconds, then go up to 16 seconds, then in for 2 seconds out for 16, then in 2 out 24, then in 2 out 32, in 2 out 48, and finally in 2 out 64. I know it seems impossible to blow out the same amount of air that it took 2 seconds to inhale for 64 seconds but it is possible you will just need to work your way up to it. Keep teeth clenched when releasing air it helps keep it in longer.
2)Practice your scales daily, you know the do-re-mi crap.
3)Sing from your diaphragm. place your hand at the bottom of your ribcage you should be able to feel it.
4)drink plenty of water
5)sing with your throat and back of your mouth open, like it is when you yawn.
6)DON'T SMOKE.
7) Yoga always helps.
Keep away from caffeine.
Well, I'm by far a professional but all these things help me, so I hope they can help you.
