I have an audition in a month but am concerned because when I sing it seems that I can’t get my high notes anymore. I don’t know what it is . . . I used to get really high notes. I just came off a 2 week rest but my throat is still the same: it feels really dehydrated. Can you give me some advice please?
This sounds like you might have strained the voice — you might have a little burst blood vessel or some swelling. You will need to go to a laryngologist (ENT) immediately and have the cords looked at. If it is a small swelling you might be able to treat it with a round of steroids so that you can do the audition. However, I encourage you to work very carefully with a teacher if you choose to do this. If the voice has been stressed, you will need to work slowly, avoiding the extremes of the range, and for very short periods of time. Most importantly, you will need to stay focused and relaxed. Fear and anxiety cause tension and make matters worse. Your voice will heal and it will do so faster if you just stay calm and do the next right thing. I hope you are able to audition and I wish you the best!
