In order to unlock the full potential of your voice, you must open your consciousness to what singing really is. In order to get your mind on singing, you must come to understand the mystery behind pitch. Only then are you ready to begin the technical work on breathing and placement, and finally on acting, and connection to your lyric.
The mind is very stubborn, and responds in interesting ways to criticism during our formative years. Anyone who told you that you couldn't sing, would never be a belter, or that your talents were best suited somewhere other than musical theater, didn't quite know what they were implanting into your subconscious. Whether these criticisms came from an evaluative place or a cutting place is of little consequence. Together we will find all the weeds of self doubt that lead to feelings of unworthiness, and pull them out by the roots.
You can reclaim your full vocal potential.
