"You command your voice too much. Let it go! Be gentle!"
Wow, I really got that because I teach my students the same thing! When you're singing correctly, you don't have to 'do' anything with the voice. You don't have to push, force, or try to make the voice reach the notes. You just 'let it go', release it, let it be free to soar. That sounds simple, and it is. Singing should be simple. It should feel good, it should be easy.
So stop commanding your voice. Get out of the way and let your body do what it does naturally - produce a clear, rich, powerful voice that doesn't need you pushing or manipulating it. Really, stop thinking, stop trying. Just let the voice flow. When you develop that kind of trust you will develop a beautiful voice.
