"The voice comprises the most complicated muscle group in the entire body, using more of the cerebral cortex than any other part of the body. Because it's so complex, in a lesson you can't just say, 'change this, change that.' What I do suggest is that in order to get the result you want—and we talk about what that might be—students should try different approaches with my guidance. I'll say, 'This way might be more effective,' rather than, 'What you're doing is wrong.' I believe that if you simply tell someone that what they're doing is wrong, it makes the body tense. A tense body has a harder time singing, and that's counterproductive.
