I remember my friends saying “Wow, you have the easiest job in the world, singing!” I would think to myself, you’ve got to be kidding. They had no idea the physical effort I was enduring to keep my voice balanced and controlled, and sounding the way it did ever minute of my performance.
Sure, singing isn’t rocket science, but singing well for long periods of time is a balancing act of coordination between body, air flow and the vocal cords. If one of these is out of sync, then something has to give. Usually it’s the throat!
