It has become very clear that our voice holds power beyond our comprehension. Now that we have the understanding of the power of our voice, we must find techniques to help unlock the sustaining power in both the unconscious and conscious elements within the musical theatre style. Professor Henry Higgins offers Eliza Doolittle a wonderful word of advice, when she is discovering the power and flexibility of her own voice in the musical My Fair Lady.
“Think what you're dealing with. The majesty and grandeur of the English language, it's the greatest possession we have. The noblest thoughts that ever flowed through the hearts of men are contained in its extraordinary, imaginative, and musical mixtures of sounds. And that's what you've set yourself out to conquer. And conquer it you will.”
Eliza Doolittle was able to conquer her language barrier and you the singing actor will be able to use the techniques that follow to conquer the musical mixtures of sounds within musical theatre song!
I heartily agree with your statement "... our voice holds power beyond our comprehension." The way you relate voice to acting is very interesting. Good Job!
