Don’t hold back!
When you ever hold back on high notes, your voice can go off or break. Go to a place you are alone and then find out the real limits of your voice without hurting your throat. Make sure you take humming breaks to soothe the throat.
*Note from Your Personal Singing Guide: Tks Alana! I think what you’re trying to tell all readers is that we should not fear high notes, but to give it our best, and allow our voice to reach its fullest potential. Going to a more private place is a good idea, and this allows us to really work on our voice without disturbing our neighbours!
