I think I (a soprano 1) am having a voice change- and I have auditions for multiple things on July 7th? HELP?!

I have been a soprano one my entire life (well, since I've been singing- since I was 11- I'm no almost 16) Within the past month I've been noticing that my voice has been sounding scratchier and more whiny when I hit the high notes... And there are a couple of notes I can't hit anymore. Isn't it wat late in my life to be going through a voice change? And it's not because I suck- (not to sound like a snob but I know I've got a decent voice.) How can I make this work with my audition (One for a musical theater class, another for an advanced vocal technique class- they are NOT looking for a certain range so I can audition as an alto, mezzo, soprano, w/e.) No- I don't have a voice teacher to help me with this :(



PLEASE HELP!!I think I (a soprano 1) am having a voice change- and I have auditions for multiple things on July 7th? HELP?!
I am a classically trained singer who is majoring in vocal performance. I can't hear what is going on but I can give you some general advice. Relax relax relax. Try not to belt for very long in a day...it puts lots of stress in the chords. If you need to belt for a musical theater piece, belt it once so you know how it will sound and then practice in your head voice. Try to get your jaw, lips, tongue and neck relaxed when you sing. Don't try to sing for more than an hour a day. Hydrate lots especially because it is summer and its hotter. And as for the high notes, use good support and breathing and try to pretend like you are approaching the note from above rather then below if that makes any sense. Good luck!
