As simply as I can put it, the essence of vocal technique is this: full commitment to musical and textual truth at every moment, while keeping available as many options as possible. In other words, engage but don’t lock. Concepts like legato, support, and resonance are activities that are faithfully employed, moment to moment.
The true artist does not fret the past, fear the future, or fail to connect with the present. Free and expressive singing is empowered by constant change–sensitively responding to ideas and subtle attitudes.
