DON"T LET SOME OF THE INFORMATION SHARED ABOUT VOCAL PROBLEMS SCARE YOU!! These things are talked about as information only for those who may be having problems. Chances are that many of you have no problems at all. Information is always good to have, but if you don't suffer from any problems just store the information at the back of your mind. This way if you should ever find yourself in vocal hell you will know what to do and/or where to go for solutions.
In the meantime, just keep moving on with your 'pearlies' and enjoy the HELL out of your singing voice, whichever style(s) you sing!!!!!
